Question

List_of_subject = ['add user', 'modify user', delete user'] and so on

I have a variable called subject. so depending upon the subject other function are called.
like add_user, modify_user, delete_user and so on.

So when my subject is ‘add_user’
I want to call add_user function. I can call it like a normal function call.
But my list_of_subject is keep growing.

Can I DO :

List_of_subject.index(subject)

I get the index. So I want something like when index is 1 call add_user function.
Basically I want to link my function to list_of_subject list.
or it is ok to do this:`

if subject in list_of_subject:
  if subject == 'add user' :
        user = add_user()
  else if subject == ' modify user' 
        user = modify_user()

thanks.

thanks.

In Python, functions are first-class objects, so you can put them into a dictionary:

fn = {'add user': add_user, 'modify user': modify_user}

To then call the relevant function, use:

user = fn[subject]()
