Get int-type from 'int' string

Question

In Python, given the string\'int\', how can I get the type int? Using getattr(current_module, \'int\') doesn\'t work.

With this sort of thing, if you're expecting a limited set of types, you should use a dictionary to map the names to the actual type.

type_dict = {
   'int': int,
   'str': str,
   'list': list
}

>>> type_dict['int']('5')
5
