I'm running the latest Kali Linux with Python 3.7 and am trying to use the requests module. As you can see, I install requests but still cannot import it. Could someone help me reconcile this strange problem?

Thanks ahead of time for the help!
Since it appears you have multiple versions of Python installed you'll need to set your environment to use Python 3.7 (currently it's set to 3.5.6, and requests doesn't appear to be installed).
In your .bash_profile you could probably do:
alias python3=/path/to/python3.7
which should use the 3.7 version when you enter python3 ...

I am trying to use python-twitter (https://python-twitter.readthedocs.io/en/latest/index.html), and I am not having much luck. The python-twitter module is invoked with import twitter, unfortunately when I attempt to do that via my script from the command line it isn't working.
What's boggling my mind, is that there is no similar error when executing from the python shell.
Everything is installed correctly, it would seem:
(venv) user#computer:~/Documents/projectdir$ pip3 install python-twitter
Requirement already satisfied: python-twitter in /home/user/.local/lib/python3.8/site-packages (3.5)
Requirement already satisfied: requests-oauthlib in /home/user/.local/lib/python3.8/site-packages (from python-twitter) (1.3.0)
Requirement already satisfied: requests in /usr/lib/python3/dist-packages (from python-twitter) (2.22.0)
Requirement already satisfied: future in /usr/lib/python3/dist-packages (from python-twitter) (0.18.2)
Requirement already satisfied: oauthlib>=3.0.0 in /usr/lib/python3/dist-packages (from requests-oauthlib->python-twitter) (3.1.0)
(venv) user#computer:~/Documents/projectdir$ pip3 install twitter
Requirement already satisfied: twitter in /home/user/.local/lib/python3.8/site-packages (1.18.0)
(venv) user#computer:~/Documents/projectdir$ pip3 freeze > requirements.txt
(venv) user#computer:~/Documents/projectdir$ echo "$(<requirements.txt)"
...
python-twitter==3.5
...
twitter==1.18.0
...
And yet my script throws an error:
(venv) user#computer:~/Documents/projectdir$ sudo python3 authentication_test.py
Traceback (most recent call last):
File "authentication_test.py", line 1, in <module>
import twitter
ModuleNotFoundError: No module named 'twitter'
Despite the twitter module being found by the python shell:
(venv) user#computer:~/Documents/projectdir$ python3

>>> import twitter
>>> twitter.Api()
<twitter.api.Api object at 0x7f11b0056a60>
>>>
What's going on here? I thought maybe there was something causing issues between twitter and python-twitter, but I did pip3 uninstall twitter and the issue persists.
I should note that although I broke them up with comments, the above code snippets were done consecutively.
Ideas?
As stated by Aaron (thank you), the answer was that sudo was taking me out of the virtualenv context, and thus the packages were not available.
I'm trying to import a package called populartimes: https://github.com/m-wrzr/populartimes
I keep getting this result:
Traceback (most recent call last):

import urllib.request

Does anyone know how to fix this issue?
When I run:
pip install requests
I get:

This error leaves me nowhere to go. I followed the docs here:
https://flask-bcrypt.readthedocs.io/en/latest/
Try using from flask_bcrypt import Bcrypt.
This is because the flask documentation on flask extensions implies that extensions in the form of Flask-Foo and are imported as: from flask_foo import Foo
http://flask.pocoo.org/docs/1.0/extensions/
In the recent flask's update, from flask.ext.xxx import xxx has been removed. You should import it directly from its package. And here is a related issue.
By the way, this package seems out of date(last updates two years ago).

I get requirement already satisfied during install and then I get import error during import. Why is that ?
If you don't also have a /usr/lib/python2.6/site-packages/jinja2, it's possible that a prior install got interrupted. If that's the case, in your position I'd try removing /usr/lib/python2.6/site-packages/Jinja2-2.6-py2.6.egg and doing the install of flask==0.12 again.
There's a significantly newer version of Flask available (and Python, for that matter). I assume you have reasons for wanting something older.
Any idea how this could be fixed?

The problem is that you are running pip with sudo from the virtualenv. This temporarily makes you root, resets all the environment variables that are set by virtualenvwrapper and thus installs the packages system-wide instead in the virtualenv.
This should work better:
workon cv2
pip install keras tensorflow
Is it possible when creating cv2 environment, you did not create it with --system-site-packages flag?
If not, you can always pip install keras inside the virtualenv.
