Data Analytics

Repository of the Data Analytics module at ZHAW

ℹ️ NOTICE: Please note that the weekly material will always be available shortly before the course starts.

Getting Started

GitHub Codespaces (our working environment for the course)

Create a new codespace on GitHub. Everything should be set up as needed.

Locally (use only, if you need a clone of the GitHub repository on your local computer)

Assuming you have

• Visual Studio Code
• git
• Python3
• Created a fork of this repository and set up an SSH key

You can clone this repository to your local computer using:

git clone <repository-url>

where <repository-url> is the url of your fork (click green button above, Local, SSH).

After that, run:

cd /workspaces/data_analytics    # go to your working directory
pip install -r requirements.txt  # installs the required Python libraries

Useful git commands

Before running these commands, make sure you're in your working directory.

If not, use this command:

cd /workspaces/data_analytics  # your working directory

Clear git cache

You can clear your git history (remove files and folders from the Git index) by using the following commands

git rm -r --cached .
git rm -r --cached ./foldername
git rm --cached <filename>

Push to remote repository

git remote -v                                 # verify remote url
git remote set-url origin <url_of_your_fork>  # set remote url
git push origin main                          # push to remote

Force Push and Pull to/from remote repository

git push --force
git pull --force

Rebase

Rebase local changes on top of changes from the remote repository.

git config pull.rebase true  # run this once for working directory
git pull --tags origin main  # updates codebase

Branching

Create and change branches

git branch                 # shows current branch
git checkout main          # returns to main branch
git checkout -b week_01    # creates and changes to the new branch 'week_01'
git checkout main          # returns to main branch
