else-if-used / R5501

Message emitted:

Consider using "elif" instead of "else" then "if" to remove one indentation level

Description:

Used when an else statement is immediately followed by an if statement and does not contain statements that would be unrelated to it.

Problematic code:

if input():
    pass
else:
    if len(input()) >= 10:  # [else-if-used]
        pass
    else:
        pass

Correct code:

if input():
    pass
elif len(input()) >= 10:
    pass
else:
    pass
