Compatibility module for Python 2.7 and > 3.3¶
This module provides a set of utility types and functions for optimization and to aid in writing Python 2/3 compatibile code.
True if this version of python is 2.x.
clock() → float¶
A clock with the highest available resolution on your current Operating System.
A utility type for detecting string in a Python 2/3 friendly way. For example:
if isinstance(s, string_types): print("It's a string or unicode type") else: print("It's something else.")
isclose(a, b, *, rel_tol=1e-09, abs_tol=0.0) → bool¶
Determine whether two floating point numbers are close in value.
- maximum difference for being considered “close”, relative to the magnitude of the input values
- maximum difference for being considered “close”, regardless of the magnitude of the input values
Return True if a is close in value to b, and False otherwise.
For the values to be considered close, the difference between them must be smaller than at least one of the tolerances.
-inf, inf and NaN behave similarly to the IEEE 754 Standard. That is, NaN is not close to anything, even itself. inf and -inf are only close to themselves.
