Module 3: Command Line and Terminal

The CLI is a tool that allows you to control your system by using text-based commands.

Accessing the Terminal: You can open the terminal by using the search option on your operating system.
Default Terminals: Windows users typically have the Command Prompt and Windows PowerShell available. Mac users can open the terminal directly by searching for it.
Anaconda Prompt: The video suggests downloading the Anaconda distribution, which provides the Anaconda Prompt, a separate tool for managing environments and packages. The presenter demonstrated downloading the 64-bit graphical installer for Windows.

The CLI requires specific commands to run. The video covers basic directory management:

Command	Purpose	Applicable Operating Systems
`mkdir [directory_name]`	Creates a new directory (e.g., `mkdir abcd`).	Universal
`cd [directory_name]`	Navigates into the specified directory (e.g., `cd abcd`).	Universal
`dir`	Lists all files in the current directory.	Windows users
`ls`	Lists all files in the current directory.	Mac or Linux users
`cd ..`	Navigates backwards to the parent directory.	Universal

Python packages are libraries that can be downloaded and used for free, allowing you to use their capabilities in your applications.

Installing Packages: Use the pip install command followed by the package name (e.g., pip install pandas) to download and install a library.
Listing Installed Packages: Use the command pip list to view all packages currently installed on your system.
Default Packages: Note that many default packages automatically download once Python is installed.
