Best practices for when you are working on exercises

Shortcuts

Commenting out shortcut:

  • Select the lines you want to comment and press:
    • Windows: Ctrl + /
    • Mac: Command + /

Bash shortcuts

  • TAB - autocompletes commands, file names, or directory names for you​.

  • UP/DOWN Arrows - Scroll backward and forwards through previous commands you’ve typed in the current session. ​

  • CTRL + C - Abort the current line you’re typing or a command that is currently executing​.

When you start:

First, make sure you are using the Shell 🐚 (not the console).

While using the bash Shell, navigate the folders using the command-line and make sure you are in the same folder as the files you want to access. Ex: In order to access exercises_1.py, you have to be in intro-to-python/session_01.

Here are some CLI commands to help you out:

pwd # Prints to the console the path of your current working directory

ls # Lists the files in the directory you are in


cd <directory_name> # Gets in a given directory

cd .. # Gets out of the directory you are in

How do you run a python file?

  1. Make sure that you are using the Shell 🐚.
  2. Verify that you are in the folder containing the file you want to run. You can use pwd to check the current folder and ls to see the files in the current folder.
  3. Run python <file_name.py> (ex: python exercises_1.py).

Before you go:

When you are done for the day, don't forget to commit and push your work using the git commands:

git add . # Adds ALL changes to the staging area in preparation for committing them to the repository.​

git commit -m "<Short description of what you have worked on.>" #  Saves changes to the local repository, along with your commit message, usually describing the changes.

git push origin main # Uploads local changes to your remote repository, on the main branch.
