python: extract integers from mixed list

Question

(python 2.7.8)

I\'m trying to make a function to extract integers from a mixed list. Mixed list can be anything but the e.g. I\'m going with is:

test         


        

Answer 1

Apparently bool is a subclass of int:

Python 2.7.3 (default, Feb 27 2014, 19:58:35) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> isinstance(42, int)
True
>>> isinstance(True, int)
True
>>> isinstance('42', int)
False
>>> isinstance(42, bool)
False
>>> 

Instead of isinstance(i, int), you can use type(i) is int or isinstance(i, int) and not isinstance(i, bool).
