Python Modules
A Module defines a bunch of code which provide special features to its users out of the box.
We’ll be learning how to create a module and access it.
Creating a Module
Specify file extension as .py. Here we’ll be naming our module as NewModule.py.
We’ll assign a method which multiplies the given numbers
fruits = [
"Orange",
"Apple",
"Strawberry"
]
def myfunc(a,b):
return a*b
To use the method in the module we must include the particular module inside of python file.
Use import followed by module name in our main.py file.
import NewModule
Accessing Method’s inside Module in main.py
import NewModule k=NewModule.myfunc(9,8) print(k) #PYTHON OUTPUT 72
Accessing variables inside module
print(NewModule.fruits) #PYTHON OUTPUT ['Orange', 'Apple', 'Strawberry']
Renaming module
This is required when the module name is too long insisted calling with that name we can assign an alias to that module
import NewModule as sn k = sn.myfunc(9, 8) print(k) print(sn.fruits) #PYTHON OUTPUT 72 ['Orange', 'Apple', 'Strawberry']
Accessing classes in modules
If you wish to use a particular class/method/variable in module this can be done by from keyword.
#in NewModule.py file
class Teacher:
def set_teacher(self,name,subject):
self.name=name
self.subject=subject
def show_teacher_details(self):
return [
self.name,self.subject
]
class Student:
def set_student(self,fname,lname,age):
self.fname=fname
self.lname=lname
self.age=age
def show_student_details(self):
return [
self.fname,
self.lname,
self.age,
]
#---------------------------------------
#-----------in main.py file--------------
#---------------------------------------
from NewModule import Student as st #this will only import Student class
new_st= st()
new_st.set_student("Kane","John",18)
print(new_st.show_student_details())
#PYTHON OUTPUT
['Kane', 'John', 18]
