(PYL-W0102) Dangerous default argument #8

Open westonplatter opened 3 years ago

westonplatter commented 3 years ago

Description

Do not use a mutable like list or dictionary as a default value to an argument. Python’s default arguments are evaluated once when the function is defined. Using a mutable default argument and mutating it will mutate that object for all future calls to the function as well.
