Which pip version?
Pip is a special program used to install Python packages to your system. Pip is sometimes included automatically when Python is installed to your system, and sometimes you have to install it yourself. These instructions will help you check if pip is on your system, and help you upgrade or install it if necessary.
First, check whether pip is installed on your system:
The output of pip --version tells you which version of pip is currently installed, and which version of Python it’s set up to install packages for. This is especially helpful if you have more than one version of Python installed on your system.
If you have only one version of Python installed on your system, you can use pip to install packages. You might want to try upgrading pip first though.
If you have more than one version of Python installed on your system, you should also try the command pip3:
Here pip3 is set up to install to the same version of Python, but often times pip will install to Python 2. pip3, if you have it set up, should always install packages to the version of Python 3 you have installed.

To install pip, go to https://bootstrap.pypa.io/get-pip.py. Save the file if you’re prompted to do so; if the code for get-pip.py appears in your browser, copy and paste the entire program into your text editor and save the file as get-pip.py.
Open a terminal and navigate to the folder containing get-pip.py, and run it with administrative privileges:
After the program runs, use the command pip --version (or pip3 --version) to make sure pip was installed correctly.

Once you have pip installed, it’s good to upgrade it from time to time. Usually pip will prompt you with instructions for how to upgrade it when necessary, but you can try to upgrade manually any time. For example, here’s sample output for upgrading an out-of-date version of pip:

Once you have pip installed, most Python packages can be installed in one line. For example, here’s how you can install Requests, which is used to make API calls from Python programs:
Here pip has downloaded the files needed to install Requests, and then managed the installation for us. The --user flag means pip has made Requests available to us, but not to other users. This keeps each user’s Python packages from conflicting with each other on systems with more than one user. It’s a good idea to use this flag unless you have a specific reason not to.
Now you can start a Python terminal session, and import requests:
Here we’ve used requests to retrieve Google’s home page, and the status code of 200 tells us that the request was successful.

If you ever want to uninstall a package, you can use requests to do so as well:
Pip lists all the files that will be removed, prompts you about whether to proceed, and then uninstalls the package.

First, check whether pip is installed on your system. Open a terminal window and issue the following command:
The output of pip --version tells you which version of pip is currently installed, and which version of Python it’s set up to install packages for. This is especially helpful if you have more than one version of Python installed on your system.
If you have only one version of Python installed on your system, you can use pip to install packages. You might want to try upgrading pip first though.

You can get the current PIP version on your system by opening a terminal and typing the command: pip -V. It will show the PIP version and the Python version that is installed on the computer (if any).
PIP is a package manager for Python packages, or modules if you like.
A package contains all the files you need for a module.
Modules are Python code libraries you can include in your project.
Navigate your command line to the location of Python's script directory, and type the following:
If you do not have PIP installed, you can download and install it from this page: https://pypi.org/project/pip/
Downloading a package is very easy.
Open the command line interface and tell PIP to download the package you want.
Navigate your command line to the location of Python's script directory, and type the following:
Now you have downloaded and installed your first package!
Once the package is installed, it is ready to use.
Import the "camelcase" package into your project.
Find more packages at https://pypi.org/.
Use the uninstall command to remove a package:
The PIP Package Manager will ask you to confirm that you want to remove the camelcase package:
Press y and the package will be removed.
Use the list command to list all the packages installed on your system:
