How can I remove a string's parentheses so it can be used in functions?

Question

If I make a function call check('list') and in the function that I'm defining, which is called check, I want to use if isinstance(value, x): where x is the argument of check, currently 'list' but it may be any variable type, is there a simple way to use list instead of 'list'?

Answer 1

Same as this.

typemap = {
  'list': list
   ...
}

def check(x):
   ...
  if isinstance(value, typemap[x]):
     ...

But really you should just be passing list directly.
