The temporary decorator raises the "Optional" NoneType "object is not a throwable" exception
I have a sync function and my main function. When I only use the main function it works fine, but when I use the sync function as a decorator an exception is thrown.
Sync function code:
def timing(function):
import time
t = time.time()
function()
t = time.time() - t
print('Program has been running for {} seconds.'.format(t))
I use it like this:
@timing
def main():
#some code

The decorator needs to return a decorated function:
def timing(function):
def wrapped():
import time
t = time.time()
function()
t = time.time() - t
print('Program has been running for {} seconds.'.format(t))
return wrapped
@timing
def main():
# some code
