call list of function using list comprehension

Question

can I call a list of functions and use list comprehension?

def func1():return 1
def func2():return 2
def func3():return 3

fl = [func1,func2,func3]

fl[0]()         


        

Answer 1

Yes, you can - the functions get called as intended.

Answer 2

>>> [f() for f in fl]
[1, 2, 3]

Absolutely :)

Answer 3

Of course you can as Fábio Diniz said :), However for the class method when used as a callable, an object must be given as an argument:

fobj= F()

for f in fobj.fl:
    f(fobj)

The object must be given as an argument to the callable because when you look at the definition of the method def funcX(self): the method needs one argument "self"

Answer 4

Yes, you can. The resultant list will hold the return values of your functions.
