Python Question

Assigning a function to a variable

Let's say I have a function

def x():
print(20)


Now I want to assign the function to a variable called
y
, so that if I use the
y
it calls the function
x
again. if i simply do the assignment
y = x()
, it returns
None
.

Answer

You simply don't call the function.

>>>def x():
>>>    print(20)
>>>y = x
>>>y()
20

The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y the value returned by x (which in this case is None).
