global name 'inf' is not defined

Question

I have developed a function that was on its own in a script. I ran that script to place the function in my namespace. The line of code I have that was working fine is:

df.my_variable.replace([inf, -inf, nan, NaN], 0, inplace=True)

I have now moved this function into mymodule.py. I then try to run it:

import mymodule as mm
mm.myfun()

The line of code to replace inf, etc., now throws the following error:

global name 'inf' is not defined

I'm sure this is a legacy of developing interactively in IPython, but I'm stumped as to how I would define inf to make this work.

Answer 1

Try this:

from numpy import inf
