Python Modules
Modules in python
Python module is a file in python that contains python code like methods or functions, statements and classes etc. That code can be reused in any other file of the python by importing the module file.
Example:
#this is the module file gmodule.py
def sum():
num1=100
num2=20
res=num1+num2
print("The sum is ",res)
#now defining the second method
def subtract(n1,n2):
res=n1-n2
return res
#defining other method
#following method is taking default arguments
def multiply(n1=10,n2=5):
res=n1*n2
return res
#This is the usemodule file of python
# will import gmodule file here
import gmodule as gm
gm.sum()
gm.subtract(100,20)
ans=gm.multiply(7,8)
print("The value of ans is ",ans)
ans=gm.multiply()#using default arguments
print("The value of ans is ",ans)
ans=gm.multiply(n2=9,n1=5)#keyword arguments
print("The value of ans is ",ans)
Output
The value of ans is 56
The value of ans is 50
Some built-in modules of python :
OS module
The OS module is given by python to provide you the methods to perform some jobs which can be performed by the operating system.We are using windows operating system so we shall use some windows commands through the OS module of python.
