Plz give me concepts about identation in 'if' statement

Answer 1

It's just a syntax
for example
In other programming languages the block of code would be enclosed with { }
ex:
if(condition){
IF BLOCK STATEMENTS
}
else{
ELSE BLOCK STATEMENTS
}

Instead of this block of code differentiation
python uses, colon and intendation

ex

if(condition):
IF BLOCK STATEMENTS
else:
ELSE BLOCK STATEMENTS

as u see the curly braces replaced with colon and indentation (4 spaces by default)

It would be convenient for developers to remember the exact block of code they are dealing just by looking rather than counting the { }
Especially in complex nested if statements
Hope u got my point.

Answer 2

Definition of Indentation in English is a space before beginning of line or a paragraph.

In python 4 spaces are used for indentation in if function to differentiate from other line of codes.

Answer 3

Answer 4
