Can anyone explain this to me in very simple words?

Question

Certain restrictions apply in regard to the characters that may be used in Python variable names. The only characters that are allowed are letters, numbers, and underscores. Also, they can't start with numbers.
Not following these rules results in errors.

Answer 1

It means you can only use the 26 letters of the latin alphabet, 0-9 and this thing _ (underscore). Whatever you do, don't
1: copy another python word, like "print" or "input"
2: Don't start with a number.

Answer 2

Keywords are not allowed.Spaces are also not allowed.
We can use letters a-z A-Z and numbers 1-9 but don't use numbers in the starting
Special characters are not allowed except underscore(_)
We can use underscore instead of spaces to seperate words
Not following these rules results Syntax error

Python is a case sensitive programming language.It means there is a huge difference between capital letters and small letters
