How to add/use libraries in Python (3.5.1)

Question

I've recently been playing around with python and have now expanded into doing stuff like scraping through websites and other cool stuff and I need to import new libraries for these things like lxml, pandas, urllib2 and such. So I have Python 3.5.1 installed and is also using Wing IDE. I (think) also managed to install pip using this tutorial, but then got lost after the

Run python get-pip.py

part.

So how would I go about installing those libraries to try new projects? Thanks!

Answer 1

python 3.5 comes with pip already, to install something with it, open a cmd and do python -m pip install library to install your desire library and if you want the help on the command do python -m pip --help

Answer 2

if u have or you can create a file requirements.txt which contains the libraries that you want to install for ex:

numpy==1.14.2
Pillow==5.1.0

You gonna situate in your folder which contains that requirements.txt in my case the path to my project is

C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means

now just type

python -m pip install -r ./requirements.txt

and all the libararies that you want gonna install

C:\Users\LE\Desktop\Projet2_Sig_Exo3\exo 3\k-means>python -m pip install -r ./requirements.txt
