How to automatically install required packages from a python script as necessary?

Based on here

Let's assume that your Python script is example.py:

import os
import time
import sys
import fnmatch

If you want to make to be the same as master

git checkout development
git reset --hard master
git push -u origin <local-branch-name>

Force your forked repo to be the same as upstream. Forces master changes into fork and throws away all changes! if no upstream remote created: git remote add upstream https://[upstream guy's repo url]

git checkout master
git pull origin master
git merge test
git push origin master

Preferred workflow for this:

1. On branch master, git checkout -b user_story_1.
2. Make changes to user_story_1.
3. Open PR for user_story_1.
4. On branch user_story_1, git checkout -b user_story_2.
5. Make changes to user_story_2.
6. Once user_story_1 gets merged into master, switch to user_story_2 and do git rebase -i master.
7. This should show you a list of commits on user_story_2 that you want to include in the rebase. Delete the top few commits that came from user_story_1.
8. The rebase should complete cleanly unless master was updated with other changes. Now you have user_story_2 rebased on master and only having its commits.

Pushing to Multiple Git Repos

If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.

Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.

If in doubt about what git is doing when you run these commands, just
