If you want to put an argument in the closure function and execute it later

python


def outer(a, b):

    def inner():
        return a + b

    return inner#Returns an object instead of calling the inner function

f = outer(1,3)
print(f)
print(f())

Execution result


<function outer.<locals>.inner at 0x7**c3dfa*****>
4

in print (f) The information of the inner object is returned, a + b is not running.

If you do f (), inner will be executed.
