Python Lesson 2

Lesson # 2 Hi All, Comments Comments are very useful and important in any programming language. In python we also use comments to make our code more readable and definable. But remember ‘Code never lies, but comments lies’ – So, make your comments as per code so it exactly defines why we write a comment and what we need to explain at that time. Because programmer works with different languages and on different projects. So, write your comment in that way if you read after 1 year you remember or understand what’s the logic behind and it helps you to figure out why I write this section of code etc. Syntax of comments è In python # symbol used for comment è For multiline you can use # symbol or “”” (three times double quotation) Example # single line comment “”” Comment 1 Comment 2 “”” So, between “”” and “”” is comments in python Variables As I told in lesson 1 that in python no need to put the data type for variables in pyt...

Lesson 5 - Conditional Statements

So, in above example you use conditions. Similarly in programs we use condition to sort out the results. Another example is finding the grade based on your percentage. If percentage is between 90 - 100 your grade is A+ and so on. Syntax: The keyword 'if' is used for condition with conditional operators Example a = 20 b = 10 if a > b:     print("a is greater than b") Now you observe in above example if a is greater than b than it prints "a is greater than b" but if not than it didn't print anything. To handle this use case we use else if a > b:     print("a is greater than b") else:     print("a is not greater than b") For some cases we have multiple conditions to check for example do some ta...
