The main advantages of package statement are

• We can resolve naming conflicts
• We can identify our components uniquely
• It improves modularity of the application Eg 1: D:\Python_classes> |-test.py |-pack1 |-module1.py |-__init__.py __init__.py: empty file module1.py:

def f1():
print("Hello this is from module1 present in pack1")

test.py (version-1):

import pack1.module1

pack1.module1.f1()

test.py (version-2):

from pack1.module1 import f1

f1()

Eg 2:

D:\Python_classes>

|-test.py

|-com

|-module1.py

|-__init__.py

|-durgasoft

|-module2.py

|-__init__.py

__init__.py:

empty file

module1.py:

def f1():
print("Hello this is from module1 present in com")

module2.py:

def f2():
print("Hello this is from module2 present in com.durgasoft")

test.py:

• from com.module1 import f1
• from com.durgasoft.module2 import f2
• f1()
• f2() 5.
• Output
• D:\Python_classes>py test.py
• Hello this is from module1 present in com
• Hello this is from module2 present in com.durgasoft Note: Summary diagram of library,packages,modules which contains functions,classes and variables.
