Spyder Version: 2.2.5 Python Version: 2.7.5 Qt Version : 4.8.4, PyQt4 (API v2) 4.9.6 on Windows pyflakes >=0.5.0: 0.7.3 (OK) pep8 >=0.6 : 1.4.6 (OK) IPython >=0.13 : 1.1.0 (OK) rope >=0.9.2 : 0.9.4 (OK) sphinx >=0.6.6 : 1.2 (OK) matplotlib >=1.0: 1.3.1 (OK) sympy >=0.7.0 : None (NOK) pylint >=0.25 : 1.0.0 (OK)

What steps will reproduce the problem?

If you write a line in an editor:

Infinity = inf

the editor will complain and highlight the line and say "undefined variable inf".

What is the expected output? What do you see instead?

inf in python is a float type number, and you can assign variables to it without any problems. The highlight and warning should not be displayed

Please provide any additional information below

In both python2 and python3 I get:

inf Traceback (most recent call last): File "", line 1, in NameError: name 'inf' is not defined

However numpy.inf exists and is of type float. Did you forget "from numpy import *" or something ?

This problem was solved in version 2.3.0. Previous to that version, we imported the numpy library by default in our Python and IPython consoles and that's why it was defined there, as a float number.

Please update to avoid this and similar problems in the future. By the way, sorry for the confusion.
