R0911 (too-many-return-statements)
Problematic code:
def foo(x):
if x == 1:
return 'This is one.'
if x == 2:
return 'This is two.'
if x == 3:
return 'This is three.'
if x == 4:
return 'This is four.'
if x == 5:
return 'This is five.'
if x == 6:
return 'This is six.'
if x == 7:
return 'This is seven.'
Correct code:
NUMBERS_TO_STRINGS = {
1: 'one',
2: 'two',
3: 'three',
4: 'four',
5: 'five',
6: 'six',
7: 'seven'
}
def foo(x):
return f'This is {NUMBERS_TO_STRINGS.get(x)}.'
Rationale:
Used when a function or method has too many return statement, making it hard to follow.
