Basic Structure of Python Program! (English)

#PythonProgramming #RemoteLearning #CodinginPython Basic Structure of a Python Program! -expressions -statements -comments -function -Blocks & indentation An expression is any legal combination of symbols that represents a value. An expression represents something which python evaluates and which produces a value. E.g. 10, x + 5 A statement is a programming instruction that does something i.e. some action takes place. A statement executes and may or may not results in a value. E.g. print(x + 2), y = x + 5, x = 10 Comments are the additional readable information to clarify the source code. Comments in Python are the non-executable statements which begin with a hash symbol (#) and generally ends with end of the line. E.g. #This is a sample python program A function is a code that has a name and it can be reused (executed again) by specifying its name in the program, where needed. A function begin with ‘def’ statement E.g. goinggood( ) A group of statements which are part of another statement or a function are called block or code-block or suite in python. Indentation is used to show blocks in python. Four spaces together mark the next indent-level.
