Python passing parameters as part of the function code

Question

I have 2 functions as follows:

def test1(var):
 return var*2
def test2(var):
 return var*4

I want to pass a variable to form part of the code, something like below:

var='test2'
def new_test(var,4):
 return var(4)

And I expect the output to be 16 (i.e. output from test2)

In excel, it is achievable via the function of =indirect(...). Is there any way to achieve that in Python?

• user2357112: Is there some reason you can't do command=test2?
• user7786493: @user2357112 Hello user2357112, it is because my current problem has to do with creating a function that takes an argument which will form part of the script within the function. I just revised my codes above for further clarity.
• user7786493: In the above case, I have a new function that takes an argument (var) which will either be test1 or test2. And inside the function of new_test, it is written in a way that the argument (var) will either be test1 or test2.
• user2357112: I'm still not seeing anything here that requires you to use a string instead of the actual function object.
• user2357112: Yeah, pretty much.

Answer 1

Yes, instead of this:

var = 'test2'
def new_test(var, 4):
 return var(4)

You can do this directly:

var = test2
def new_test(var, 4):
 return var(4)

Functions are first class objects in Python.
