Python Packages
In this blog you will get to know that what is meant by packages.
Packages are a platform which performs a big part of role in our python program.
Let’s get know more then . . . . . . . .
Mostly what happens 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, offers industry-oriented Python Training in Pune
This is the same procedure followed by package it means a package takes python in modular approach which is the next logical level in 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 )
