Installing Python

Until now, you've written Python in the browser. Install Python 3 on your computer so you can run BookBot locally.

Assignment

Follow the instructions for your operating system.

You may already have Python 3 installed. Check by running:

python3 --version

If that worked, skip to the submission step.

If the command failed and you're using Ubuntu (including WSL 2's default distribution) or Debian, install Python 3 with apt:

Update the available package list and install Python 3:
```
sudo apt update
sudo apt install -y python3
```
Verify the installation:
```
python3 --version
```

If your Linux distribution doesn't use apt, install Python 3 with its package manager, then run python3 --version.

Submit the CLI tests. There's no penalty on failure for this lesson.

We'll use the Homebrew package manager to install Python 3.

If that command failed, install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Follow any post-installation shell instructions that Homebrew prints, then restart your shell.
Install Python 3:
```
brew install python
```
Verify the installation:
```
python3 --version
```

That command should print a Python 3.x version.
