This aptly demonstrates the use of the while statement. <br style="box-sizing: border-box;" />First, we check if the variable 'running' is True and then proceed to execute the corresponding while-block. After this block is executed, the condition is again checked, which in this case is the 'running' variable. If it is true, we execute the while-block again, else we continue to execute the optional else-block and then continue to the next statement. <br style="box-sizing: border-box;" />The else block is executed when the while loop condition becomes False. <br style="box-sizing: border-box;" />The True and False are called Boolean types and you can consider them to be equivalent to the value 1 and 0 respectively.</span></div> <h2 style="background-color: white; box-sizing: border-box; color: #333333; font-family: 'trebuchet ms'; font-size: 22px; font-weight: 500; line-height: 1.1; margin-bottom: 10px; margin-top: 20px;"> The for..in loop</h2> <div style="background-color: white; box-sizing: border-box; color: #333333; line-height: 16.8831px; margin-bottom: 10px; text-align: justify;"> <span style="font-family: Courier New, Courier, monospace; font-size: large;">This for..in statement is an another looping statement.It iterates over a sequence of objects.

In the above program range(1,6) gives the sequence [1,2,3,4,5]. By default range takes a step count of 1. If we supply third number then that becomes the step count.In the above code if we had written range(1,6,2) will give [1,3,5]. range() generates the sequence of numbers but will generate only one number at a time. Remember that range extends up to the second number i.e it does not include the second number.</span></div> <div> <br /></div> </div>

Good thing about a list is that items in a list need not all have the same type.</span></div> <div style="background-color: white; box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="font-family: "courier new" , "courier" , monospace; font-size: large;">Creating a list is as simple as putting different comma-separated values between square brackets. For example:</span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">list1 = ['physics', 'chemistry', 1997, 2000]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">list2 = [1, 2, 3, 4, 5 ]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">list3 = ["a", "b", "c", "d"]</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;">NOTE:Like string indices, list indices start at 0, and lists can be sliced, concatenated and so on.</span></span></div> <h3 style="background-color: white; box-sizing: border-box; font-family: 'trebuchet ms'; line-height: 1.1; margin-bottom: 10px; margin-top: 20px; text-align: left;"> <span style="background-color: yellow; color: #333333; font-weight: 500; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span><span style="color: #20124d; font-size: large;">Accessing values in Lists:</span></h3> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: white; line-height: 18.5714px;"><span style="font-family: "courier new" , "courier" , monospace; font-size: large;">To access values in lists, use the square brackets for slicing along with the index or indices to obtain value available at that index. Following is a simple example:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">list1 = ['physics', 'chemistry', 1997, 2000]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print (list1[1:3])</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: white; line-height: 18.5714px;"><span style="font-family: "arial" , "helvetica" , sans-serif; font-size: large;">OUTPUT:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan; font-family: "courier"; line-height: 20px; text-align: left;">['chemistry', 1997]</span></div> <h3 style="background-color: white; box-sizing: border-box; color: #333333; font-family: 'trebuchet ms'; font-size: 22px; line-height: 1.1; margin-bottom: 10px; margin-top: 20px; text-align: left;"> Updating List:</h3> <div> <span style="background-color: white; color: #333333; line-height: 18.5714px; text-align: justify;"><span style="font-family: "courier new" , "courier" , monospace; font-size: large;">You can update single or multiple elements of lists by giving the slice on the left-hand side of the assignment operator, and you can add to elements in a list with the append() method. Following is a simple example:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">list = ['physics', 'chemistry', 1997, 2000]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print ("Value available at index 2 : ")</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print list[2]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">list[2] = 2001</span></span><span style="background-color: cyan; font-family: "courier"; line-height: 20px; text-align: left;">Value available at index 2 :</span><br /> <span style="background-color: #f6f6f6; font-family: "courier"; line-height: 20px; text-align: left;">1997</span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: white; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;">OUTPUT:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">New value available at index 2 :</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">2001</span><span style="line-height: 18.5714px;"><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print ("New Value available at index 2 : ")</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print (list[2])</span></span></span></div> <h3 style="background-color: white; box-sizing: border-box; color: #333333; font-family: 'trebuchet ms'; font-size: 22px; line-height: 1.1; margin-bottom: 10px; margin-top: 20px; text-align: left;"> Delete List Elements:</h3> <div> <span style="background-color: white; color: #333333; line-height: 18.5714px; text-align: justify;"><span style="font-family: "courier new" , "courier" , monospace; font-size: large;">To remove a list element, you can use either the del statement if you know exactly which element(s) you are deleting or the remove() method if you do not know. Following is a simple example:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">list1 = ['physics', 'chemistry', 1997, 2000]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print (list1)</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">del list1[2]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print ("After deleting value at index 2 : ")</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">print (list1)</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: white; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;">OUTPUT:</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: cyan;"><span style="font-family: "courier"; line-height: 20px; text-align: left;">['physics', 'chemistry', 1997, 2000]</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">After deleting value at index 2 :</span><br style="box-sizing: border-box; font-family: Courier; line-height: 20px; text-align: left;" /><span style="font-family: "courier"; line-height: 20px; text-align: left;">['physics', 'chemistry', 2000]</span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div class="separator" style="clear: both; text-align: center;"> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4NcRPn7r19oriqzQaCZi4OVMIENxu389tqsXj4BmQ2GUdIFdcfkfWp0WQr3ZXX0ay5Vwmq4tN6MB7UIljvqm-kLNRmeoAOtVeC88omHxwiFkZbdNO7zdHOIVF0NhA2W-TvyE93S2dUPZM/s1600/keep-calm-and-code-python_BW.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4NcRPn7r19oriqzQaCZi4OVMIENxu389tqsXj4BmQ2GUdIFdcfkfWp0WQr3ZXX0ay5Vwmq4tN6MB7UIljvqm-kLNRmeoAOtVeC88omHxwiFkZbdNO7zdHOIVF0NhA2W-TvyE93S2dUPZM/s400/keep-calm-and-code-python_BW.png" width="342" /></a></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <span style="background-color: yellow; font-family: open-sans; line-height: 18.5714px;"><span style="font-size: large;"><br /></span></span></div> <div style="box-sizing: border-box; color: #333333; line-height: 18.5714px; margin-bottom: 10px; text-align: justify;"> <br /></div> </div>

This course uses versions of Python 3.3. The learning curve for python is not steep, its pretty simple but at the same time, very powerful. Its heavily used in Scientific research. This course is for amateurs who are taking their first shot at programming, and also for someone who already has some programming experience in some other languages and wants to learn something new!</span></span><br /> <span style="background-color: white;
