What is Python's PIP and how to use it

What is PIP?

PIP is a package manager for Python packages or modules.

Note: If you are using Python 3.4 or higher, PIP is included by default.

What is a package?

The package contains all the files required by the module.

Modules are libraries of Python code that you can include in your projects.

Check if PIP is installed

Navigate the command line to the location of the Python scripts directory and type the following:

Example

Check the PIP version:

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip --version

Install PIP

If PIP has not been installed, you can download and install it from the official website: Python official website

Download package

Downloading packages is very easy

Open the command line interface and tell PIP to download the packages you need

Navigate the command line to the location of the Python scripts directory and type the following:

Example

Download the package named "camelcase":

C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip install camelcase

Now, you have downloaded and installed the first package!

Use the package

After installing the package, you can use it.

Import the “camelcase” package into your project.

Delete package

Please use the uninstall command to delete the package:

Example

Uninstall the package named "camelcase":
