[New-bugs-announce] [issue24059] Minor speed and readability improvement to the random module

[Raymond Hettinger]

New submission from Raymond Hettinger:

Replace all the _sqrt(x) calls with x ** 0.5, improving the visual appearance and providing a modest speed improvement.

$ python3 -m timeit -s 'from math import sqrt' 'sqrt(3.14)'
10000000 loops, best of 3: 0.032 usec per loop
$ python3 -m timeit -s 'from math import sqrt' '3.14 ** 0.5'
100000000 loops, best of 3: 0.0101 usec per loop
