trying import in Python

[pegasis]

on windows 8.1:


my python folder is C:\Python27

python will not run from the command prompt.. it will only run once I have changed directories to C:\Python27

I have updated the path to include C:\Python27

why doesn't it run from the command prompt?



I can't seem to import anything in idle

I get this error: import nympy

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import nympy
ImportError: No module named nympy

I am trying to import nympy, matplotlib, and sklearnit

please help

You need to add the python directory to your path. See instructions: http://www.howtogeek.com/118594/how-to-edit-your-system-path-for-easy-command-line-access/

For the second part have you actually installed those modules?

I did add Python27 to my path

and No I have not installed those modules

import nympy
ImportError: No module named nympy

Also, I don't recognize the "nympy" module. But NumPy is a well-known advanced math module.

when you add it to the path, you need to restart the command prompt. change takes effect only on the newly created processes.

You will need to install those modules before you can import them.

You might want to try out pip. It's a package manager for python. ("pip install numpy", and so on.)
