flake8: ignore F841 unused variable for variable name _ex

Question

I have the following code and expecting flake8 not to raise any error as the variable name _ex starts with a underscore. But flake8 still gives me F841 local variable '_ex' is assigned to but never used error. How can I get rid of the error?

try:
    1/0
except ZeroDivisionError as _ex:
    print("zero division error")

Answer 1

I just dropped the variable and it worked

try:
    1/0
except ZeroDivisionError:
    print("zero division error")
