Python - Check type of values

More than 5 years have passed since last update.

Ref:
[1] - Stackoverflow - What's the canonical way to check for type in python?

Exact type

if type(o) is str:
  print "this is a string"

Instance of type or instance of the subclass

if isinstance(o, str):
  print "this is a string or a instance of subclass of string"

There are more patterns in the reference to deal with more complex usecases.
