Python functions are code blocks that can be called from some other place in the program.

Operators allow us to perform specific operations on variables. There are different types of operators in Python such as arithmetic, boolean, etc.

Datatypes define the type of data. Python is not a strictly typed language, which means we don’t have to specify the type of variable at the time of declaration.

Python statements are grouped together using indentation. So, it’s a good idea to learn about it because one small indentation mistake can cause your code to move into some different block causing unwanted effects.

Statements are instructions given to Python interpreter to execute some specific logic. Let’s learn everything about statements in this video.

Docstrings (Documentation Strings) in Python is text or string literal specified in source code as comment to document a specific part of the program.

Comments are used to leave important information about the program. We can have multi-line comments in Python too.

Variables are used to store values and then reference them in other parts of the program. Every variable has a scope based on the location of the definition.

Identifiers are name given to a Python program element such as variables, functions, class name, etc. There are certain rules and best practices to follow if you want to to write Python program in a true pythonic way.

Python keywords are a list of reserved words used by Python interpreter. So, we can’t use them in our program. We can’t create a variable or function name with the same name as these keywords.
