Using list comprehension how to call list of function

0 votes

Can i use list comprehension and call list of function?

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

fl = [func1,func2,func3]

fl[0]()
fl[1]()
fl[2]()

I know I can do

for f in fl:
   f()

but can I do below ?

[f() for f in fl]

A additional question for those kind people, if my list of functions is in class, for example

class F:

    def __init__(self):
        self.a, self.b, self.c = 0,0,0

    def func1(self):
        self.a += 1

    def func2(self):
        self.b += 1

    def func3(self):
        self.c += 1

    fl = [func1,func2,func3]

fobj= F()

for f in fobj.fl:
    f()

does it work?

For the class method when used as a callable, an object must be given as an argument:

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"

fobj= F()

for f in fobj.fl:
    f(fobj)
