Modules:
========

group of functions, variables and classes into a file ==> a module.
==> .py file ==> a module
	{
		functions,
		variables,
		classes
		objects
	}

Module:
=======

x = 1234    # variable

def add(p,q):   # function-1
    s = p + q
    return s

def product(x,y):   # function-2
    m = x * y
    return m

class employee: # class
    def __init__(self,name,role,age,salary):
        self.name = name
        self.role = role
        self.age = age
        self.salary = salary

    def employeeData(self):
        print("The Details of the Employee:")
        print("Name = ",self.name)
        print("Disgnation = ",self.role)
        print("Age = ",self.age)
        print("Salary = ",self.salary)

==========================
practice file:
==============

import mod11

# Accessing the variable of mod11
# syntax: module-name.variable-name

print(mod11.x)

# checking of even or odd
if mod11.x % 2 == 0:
    print(mod11.x,"is an even number.")
else:
    print(mod11.x,"is an odd number.")

# accessing of the functions
# syntax: module-name.function-name(val1, val2, val3,..)

result1 = mod11.add(1234,3456)
result2 = mod11.product(26,27)

print("The Sum = ",result1)
print("The Product = ",result2)

# Accessing of the class
# creating the object

obj1 = mod11.employee("Sahithi","Software Engineer", 22, 600000)
obj1.employeeData()

============================================

Importing the module with different name:
=========================================

import mod11 as calculation

# accessing variable

print(calculation.x)

# access the functions

print(calculation.product(10,20))

# create the object for the class of mod11 using alias name

obj = calculation.employee("Kumar", "Sr. SOftware Engineer", 28, 1500000)

obj.employeeData()

===========================================

Importing of Selected member from the module
============================================

Syntax:
	from module-name import member-name, member-name1,...

to access the members:
Syntax:
	member-name

# importing the selected member from the class

from mod11 import employee,add

# syntax: member-name
# object-name = class-name()

emp = employee("Rahul","Software Developer", 29, 1600000)

emp.employeeData()

print("The Sum = ",add(100,200))

================================

Member Aliasing:
================
Syntax:
	from module-name import member-name1 as new-name1, member-name2 as new-name2,...

from mod11 import x as var, add as Addition, product as Multiplier, employee as Employee

print(var)

print("The Sum = ",Addition(123,345))
print("The Product = ",Multiplier(12,23))

emp = Employee("Ashwini","Sr. Software Developer", 28,1600000)

emp.employeeData()

==============================================
dir():
=====
is an inbuilt method which we can use to get all the member names from  the specified module.

Syntax:
	dir()

==========================================

Math Module:
============

from math import *

print(sqrt(97))
print(ceil(1.234))  # for the given float, the next highest integer value can be returned
print(floor(1.234)) # for the float, the before integer value (less than the given)
print(pow(9,7))
print(fabs(12))
print(fabs(-12))
print(log(10))
print(log2(10))
print(sin(23))

===========================================

Random Module:
==============
from random import *

# random() ==> generate a random number from 0 to 1

print(random())

# randint() ==> generate a random integer from the specified range

print(randint(10,100))

# uniform() ==> to generate a float value from the specified range

print(uniform(1,10))

# randrange() ==> can generate an integer randomly from the specified range with difference/step

print(randrange(1,100))
print(randrange(1,100,10))  # 1, 11, 21,31,41,51,61,71,81,91

# choice() ==> can define with collections
# to generate the element from the collection randomly.

list1 = ["Apple", "Banana", "Papaya", "Mango", "Kiwi", "Jack-Fruit", "pineapple"]

print(choice(list1))
