44def all_exception_handler(error):45 return render_template('error.html')

Description
An unused argument can lead to confusions. It should be removed. If this variable is necessary, name the variable _ or start the name with unused or _unused.
Bad practice
def square(x, y=1):
return x * x
class MySubClass(MyClass):
def __init__(self, number):
self.value = 42 # argument `number` remains unused
Preferred:
def square(x):
return x * x
class MySubClass(MyClass):
def __init__(self, _):
self.value = 42
