Description
This issue concerns that one or more nested classes/functions have been declared but are nowhere used in the function.
A class or function defined inside a function is only accessible inside its parent function scope. It is recommended either to remove the unused classes and functions as it is a dead code or refactor it to use them.
Note: DeepSource will remove all the unused nested definitions during Autofix.
Bad practice
def run():
def total_time():
return Something
class Runner:
def __init__(time):
pass
Preferred
def run():
def total_time():
return Something
class Runner:
def __init__(time):
...
t = total_time()
bill = Runner(t)
...
