What is PIP?
PIP is a package manager for Python packages, or modules if you like.
Note: If you have Python version 3.4 or later, PIP is included by default.
What is a Package?
A package contains all the files you need for a module.
Modules are Python code libraries you can include in your project.
Check if PIP is Installed
Navigate your command line to the location of Python’s script directory, and type the following:
Example
Check PIP version:
C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip –version
Install PIP
If you do not have PIP installed, you can download and install it from this page: https://pypi.org/project/pip/
Download a Package
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:
Example
Download a package named “camelcase”:
C:\Users\Your Name\AppData\Local\Programs\Python\Python36-32\Scripts>pip install camelcase
Now you have downloaded and installed your first package!
Using a Package
Once the package is installed, it is ready to use.
Import the “camelcase” package into your project.
Example
Import and use “camelcase”:import camelcase
c = camelcase.CamelCase()
txt = “hello world”
print(c.hump(txt))
Output:
C:\Users\My Name>python demo_camelcase.py
