 No Module of this name found
#1
I entered the code for a spirograph printing program which was in the book "python playground" by Mahesh Venkitachalam only to find that it would not run.
The error:
Error:
Traceback (most recent call last): File "C:\Users\New\Andys Docs\Python\Scripts\spiro.py", line 5, in <module> import numpy as np ImportError: No module named 'numpy'
and, after commenting that line and rerunning, got:
Error:
Traceback (most recent call last): File "C:\Users\New\Andys Docs\Python\Scripts\spiro.py", line 9, in <module> from PIL import image ImportError: No module named 'PIL'
The modules not being available surprised me somewhat as I thought that 'numpy' at least was downloaded with Python as standard.
I am using Python 3.5.0 under Microsoft Windows 10. I have not tried anything else because, quite frankly, if the modules are not on my machine, then I don't know what to do next. Can someone please tell me how to resolve these problems?

The modules need to be installed before you can import and use them.
Running commands
pip install numpy
and
pip install pillow
in terminal should do. Make sure you have activated a virtual environment first, in case you are using one.

Many thanks. Numpy installed fine but I got loadsa and loads of (to me) gobbledygook when I tried to install Pilllow, which I have included in full below:

You are using pip version 7.1.2, however version 18.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

This seems to imply that something called 'zlib' cannot be found. This does not mean anything to me. I have read the installation notes and I'm afraid I could not make any sense of those either. Can you help further?
By the way, I thought PIP was a linux package manager. I didn't know that it could be used with Windows.

pip is Python installer for all OS.
You should upgrade,this is easier and better the troubleshoot that error on 3.5.
Python 3.6/3.7 and pip installation under Windows.
Test install pillow,Python 3.7 and pip 18.1.
C:\>pip -V
pip 18.1 from c:\python37\lib\site-packages\pip (python 3.7)

Thanks Snippsat. I updated pip as per the instructions at the end of the pillow installation - which seemed fine. I then reinstalled pillow (with a small 'p' as per your post). Both modules are now installed correctly on my computer.
