Pi modules and %timeit

[Gribouillis]

There is nothing special with pi. It is just a constant data in a module. There should be no significant difference between assigning math.pi versus numpy.pi or any other constant such as sys.version for example

>>> from timeit import timeit
>>> timeit('x = math.pi', setup='import math', number=10_000_000)
0.32607505199848674
>>> timeit('x = numpy.pi', setup='import numpy', number=10_000_000)
0.4240568519962835
>>> timeit('x = sys.version', setup='import sys', number=10_000_000)
0.3458355639959336
>>> 

Once again

>>> timeit('x = math.pi', setup='import math', number=10_000_000)
0.32594562199665233
>>> timeit('x = numpy.pi', setup='import numpy', number=10_000_000)
0.29548215300019365
>>> timeit('x = sys.version', setup='import sys', number=10_000_000)
