python - Don't understand these ModuleNotFound errors

Question

I am a beginner and learning Python. I have setup the environment with SublimeText and Python3.x

I am fine in creating code on Sublime and building it locally through Ctrl+B and for input() function I installed SublimeREPL and it works find up till now.

The issue I am facing is on Python interpreter. I am facing below error while import any package:

import tweepy

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'tweepy'

I cannot even run a Python script from there. My Python path is below:

C:Userswaqas.FVCAppDataLocalProgramsPythonPython37-32

Demo.py and hello.py are the two scripts I wrote initially which I am trying to execute from Python Terminal, but it is showing below errors:

test.py

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'test' is not defined

Demo.py

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'Demo' is not defined

The initial Python download includes a number of libraries, but there are many, many more that must be downloaded and installed separately. Tweepy is among those libraries.

You can find, and download, tweepy from here:

https://pypi.org/project/tweepy/
