Example 3: python how to import module

#IGNORE STEP 1, 2 AND 3 IF YOU ALREADY HAVE PIP INSTALLED
#REFER TO THE SOURCES IF YOU HAVE AN ERROR WITH YOUR PIP FOR WINDOWS
Step 1) Go to your command terminal, (aka command prompt, MacOScommandline, Command line for linux)
Step 2) You will have to install something called pip. 

#Windows
py -m pip install --upgrade pip #I mainly use windows
#If an error for window says "no recognised as internal or external command"
#Please refer to the video in the sources.

#Linux
apt-get install python3-pip

#MacOs
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
sudo easy_install pip

step 3) #Great, now you do not need to re install, meaning do the last 2 steps
#Ever again until you delete pip. 

pip install [name of module]

step 4) #implementing it into python

#Method 1
from [name of module] import [package name] #Will derrive only the package from that module

#Method 2
import [name of module] # will incorporate the whole package

#How to change the name used for your packages

import [name of module] as [name of your choice]

from [name of module] import [package name] as [name of package of your choice]

#Good luck to all my future Software engineers.
