Python Packages
In this blog, you will get to know what is meant by Python packages.
Packages are a platform that performs a big part of the role in our Python program.
Let’s get to know more then . . . . . . . .
Mostly what happens is that we organize our data in folders or sub-folders in file format. So that due to this we can easily gate our data while searching. SevenMentor is the best Python Classes in Pune, and offers industry-oriented Python Training in Pune
This is the same procedure followed by a package it means a package takes Python in a modular approach which is the next logical level in the programming world.

As we know that module contains functions, methods, algorithms, classes, objects. Etc. so a package contain relevant modules.

So let’s start to create a package : > > > > > > > > > > > >
Following are the steps to create a package: :
Step 1 :
Create a new folder in F : > myappln
Step 2 :
Inside that folder create a sub folder named as mypackge
Step 3 :
Inside that folder create a blank file named as __init__.py
Step 4 :
Now create modules like greet.py and fun.py with help of following code :
Greet.py
Def greeting ( name ) :
Print ( “ hello “, name )
Fun.py
Def sum (q , p ) :
Return q + p
Def average ( r, s ) :
return ( r + s ) / 2
Def power ( t , u ) :
Return t * * u

So now its time to check where we create the package by our own so its working successfully or not . . . . ?
For that what we need to do is go through conitue steps :
Step 5 : Go to command prompt and enter directory :
Step 6 : Change your directory like this :
C:> cd f:
F:> cd myappln
F : / myappln : > python
Step 7 : Now its time to import our package
> > > from mypackge import fun
> > > fun . power( 3 , 2 )

So this is the way to create your own package and implement in program . like this we can call our another functions also which are defined in program :
> > > fun . average ( 4 , 6 )
5
Next function is :
> > > fun . sum ( 5 , 9 )
11
The another way to write the program is like
> > from mypakge . fun import sum
> > > sum ( 3, 6 )
