too-many-return-statements / R0911

Message emitted:

Too many return statements (%s/%s)

Description:

Used when a function or method has too many return statement, making it hard to follow.

Problematic code:

def to_string(x):  # [too-many-return-statements]
    # max of 6 by default, can be configured
    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 to_string(x):
    return f"This is {NUMBERS_TO_STRINGS.get(x)}."
