Modules and Packages in Python in Hindi (Part -16)

Modules and Packages

Modules aur Packages sunne mai kafi fancy term lag raha hai, lekin is post ko padhne ke baad apko clear hojayega ki modules aur packages kya hai ?

let's suppose apne ek python program banaya aur usse save kr diya rishabh.py name se, aur fir apne ek dusra program banaya aur ussse save kr diya gupta.py name se , to basically rishabh.py ek module ho gya aur ussi tarah gupta.py bhi ek module ho gya aur har module ke andar kuch classes hongi kuch , kuch functions honge , aur ham in classes or function ka use kr skte hai dusre program mai import statement ki madad se jo ki hm aange dekhne wale hai , to basically module .py name se save koi bhi python program hogaya, to ab baat krte hai ki packages kya hote hai , to packages basically collection of modules and empty __init__.py file hote hai, to agar upar wala example le to agar hm rishabh.py , gupta.py aur empty __init__.py file ko ek folder mai rakhe to vo folder ek Package kahelayega.

module - rishabh.py, gupta.py etc.

package - rishabh.py + gupta.py +empty __init__.py file

Python mai abhi tak aprox 130k+ Packages hai.

Hm in packages aur modules ka use apne program mai kr skte hai by using import statement , aur ham khud ke modules aur package bna skte hai

Let's take an example

Hamne ek program banaya

---------------------------------------------------------------------------------

def func_in_mymodule():

print("I am a function inside of the mymodule.py file!")

--------------------------------------------------------------------------------

aur is program ko hmne mymodule.py file se save kr liya aur ham isksa use dusra program mai kai tarike se kr skte hai, jaise....

---------------------------------------------------------------------------------

#Tarika - 1

import mymodule

mymodule.func_in_mymodule()

----------------------------------------------------------------------------------

#Tarika - 2

import mymodule as mm

mm.func_in_mymodule()

----------------------------------------------------------------------------------

#Tarika - 3

from mymodule import func_in_mymodule

func_in_mymodule()

--------------------------------------------------------------------------------

#Tarika - 4 (worst tarika)

from mymodule import *

func_in_mymodule()

#Ye sbse kharab tarika hai, * ki madad hm saare classes aur functions ko import kr lete hai , ye basically code readabiliy ko kam kr deta hai, isliye ye sbse ghatiya tarika mana jata hai.
