I'm trying to call a function inside another function in python, but can't find the right syntax. What I want to do is something like this:
def wrapper(func, args):
func(args)
def func1(x):
print(x)
def func2(x, y, z):
return x+y+z
wrapper(func1, [x])
wrapper(func2, [x, y, z])
In this case first call will work, and second won't. What I want to modify is the wrapper function and not the called functions.
To expand a little on the other answers:
In the line:
def wrapper(func, *args):
The * next to args
means "take the rest of the parameters given and put them in a list called args
".
In the line:
func(*args)
The * next to args
here means "take this list called args and 'unwrap' it into the rest of the parameters.
So you can do the following:
def wrapper1(func, *args): # with star
func(*args)
def wrapper2(func, args): # without star
func(*args)
def func2(x, y, z):
print x+y+z
wrapper1(func2, 1, 2, 3)
wrapper2(func2, [1, 2, 3])
In wrapper2
, the list is passed explicitly, but in both wrappers args
contains the list [1,2,3]
.
