This looks like a decorator function that optionally accepts arguments to change the behavior.
You can safely ignore the warning form PyCharm. the variable won't be shadowed it's included in the function signature of the inner function. A lot of times, the outside decorator will just use the *args or **kwargs parameters and check whether the first arg is callable or not and if any keywords have been passed in to decide which version of the wrapped function to return Here is an example: http://stackoverflow.com/questions/653368/how-to-create-a-python-decorator-that-can-be-used-either-with-or-without-paramet On Tue, Sep 13, 2016 at 9:40 AM, Chris Angelico <ros...@gmail.com> wrote: > On Wed, Sep 14, 2016 at 2:34 AM, Daiyue Weng <daiyuew...@gmail.com> wrote: > > Hi, I am using inner function like this, > > > > def timeit(func=None, loops=1, verbose=False): > > if func is not None: > > def inner(*args, **kwargs): > > > > # some code > > > > return inner > > else: > > def partial_inner(func): > > return timeit(func, loops, verbose) > > > > return partial_inner > > > > > > PyCharm warns about "Shadows name 'func' from outer scope" on > > > > def partial_inner(func): > > > > How to fix it? > > > > cheers > > Hmm.
