Python Float Formatting Weirdness?

I'm trying to debug two different python scripts that execute very similar code. These scripts set a, which is a simple float. For script 1: ipdb> print sys.version 2.7 (r

Solution 1:

The str representation of a float truncates to 12 digits on Python 2. This is unfortunate. You have to print repr(a) to make sure you see enough precision to uniquely identify the float. There's probably a tiny difference that only shows up after 12 digits.

On Python 3, str and repr produce the same output for floats, so you wouldn't have this problem.
