Multi functions working in python

Question

Why these two aren't same
def mul(a,b,c):
return a*b*c
def add(b,a,c):
return a+b-c
def doub(lol,pol,a,b,c):
return (lol(a,b,c)) + (pol(a,b,c))
print(doub(mul,add,5,7,8))

def mul(a,b,c):
return a*b*c
def add(b,q,c):
return a+b-c
def doub(lol(a,b,c),pol(a,b,c):
return lol(a,b,c) + pol(a,b,c)
print(doub(mul(5,7,8),add(5,7,8)))

Answer 1

Because this syntax is wrong

doub(lol(a, b, c), pol(a, b, c)):

you can pass function as an argument but cannot pass with parameters

Answer 2

This means if you want to pass two functions in a single function they both must have same arguments?
