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.

kivy.compat.PY2 = False

True if this version of python is 2.x.

kivy.compat.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")
    print("It's something else.")

alias of str

kivy.compat.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.
