where exactly the numpy files are getting stored in path...
It get stored in
site-packages folder eg
C:\Python37\Lib\site-packages\numpy
Quote:how do we locate those files with help of python command??
Python locate it for you when using
import,you never need to go yourself to
site-packages folder.
C:\
λ python

>>> import numpy as np
>>>
>>> np.arange(15).reshape(3, 5)
array([[ 0, 1, 2, 3, 4],
[ 5, 6, 7, 8, 9],
[10, 11, 12, 13, 14]])How it work as looked upon from outside.
Windows find Python when it set in
Environment Variables Path,this get done automatically under install if mark on eg
Add Python 3.7 to PATH
Python finds files(module/package) by looking in
sys.path.
>>> import sys
>>>
>>> sys.path
# List get back here is where Python look

python command
