Remove __pycache__ and .pyc files from your repo

Hey MSE,

your repo contains a lot of .pyc files and __pycache__ folders. These are not important for your python code.
There is no need for them to be pushed on GitHub. To make sure that doesn't happen again, add the following lines to your .gitignore file.
```
__pycache__/
*.py[cod]
```
