How To Make Pip Install For Python 3

Python comes with several born modules, but the Python community has more to offer. It's the modules that makes python so powerful!

Third party modules add then much more functionality to Python. And so it'due south time to learn how to install these modules so that we can use those in our programs.

The simplest way is to apply pip

                pip install <module_name>              

If you have used npm, then you can think of information technology as npm of Python.

Side note: The difference is that with npm, npm install past default installs packages locally to a projection, whereas pip install by default installs globally.

To install modules locally, you demand to create and activate what is chosen a virtual environment, then pip install installs to the folder where that virtual surroundings is located, instead of globally (which may crave ambassador privileges).

Last fourth dimension, in import-statements wiki we used requests module as an example. Equally it is a third party module nosotros have to install information technology separately after installing python.

Installing information technology would be as simple every bit pip install requests . You tin even pass various arguments along with it. The 1 that you'll come across more often is --upgrade. You tin upgrade a python module by :

                pip install <module_name> --upgrade              

For case, to upgrade the requests module to its latest version would be as elementary equally pip install requests --upgrade.

Earlier using pip, you volition need to install it (it's quite simple). Yous can install it from here

Just click on the link. And save the file asget-pip.py Please don't forget the .py extension. And run information technology.

An alternative to using pip would be to try easy_install.

Using easy_install is besides uncomplicated. The syntax is:

                easy_install <module_name>              

However, pip is more pop than using easy_install.

Notation: On some systems where both Python 2 & Python three are installed, pip and pip3 will do different things. pip installs the Python 2 version of the bundle, and pip3 will install the Python 3 version of the packet.

For more information on the difference betwixt Python 2 & 3, see this guide. You tin can cheque the pip version by doing pip --version and/or pip3 --version:

                pip3 --version pip 18.0 from /usr/local/lib/python3.v/dist-packages/pip (python three.5)              

We tin can as well create a txt file containing a listing of modules which should be installed using pip. For example, we could create the file requirements.txt and its content:

                Kivy-Garden==0.1.4 macholib==1.5.1 idna==two.half dozen geoip2nation==0.i.2 docutils>=0.14 Cython              

In this file we could as well set a version for the installation. After this, by invoking pip with:

                                  pip install -r <FILE CONTAINING MODULES>             OR IN OUR Example    pip install -r requirements.txt                              

information technology should install all the modules listed on the file.
