How to change name of a list in python according to function arguments

Question

Suppose we have a function

def analyse(n):
      for c in cluster_{n}:
             do something

For example if we run analyse(1) I want it to run like

for c in cluster_1 :
         do something

where cluster_1 is a global list already declared.

How can I do that?

Just *pass the list as an argument*. Don't dynamically access global variables. — juanpa.arrivillaga, Apr 17 '22 at 08:28
but how can we do it if i want multiple lists without passing all those arguments — Shail Jadhavrao, Apr 17 '22 at 08:29
I'm not sure exactly what you mean, but top thinking in terms of *variables* think in terms of objects. What *object/data structure* do you need for your problem? — juanpa.arrivillaga, Apr 17 '22 at 08:32

As mentioned in comments, you can pass the list as argument directly.

Another way to do so is to create a dictionary and store all the global lists in it, like this;

obj = {"cluster_1": [1, 2, 3, 4, 5]}

def analyse(n):
      for c in obj[f'cluster_{n}']:
             print(c)


analyse(1)
