OOPs in Python

Components of a class
1.    Data members
2.    Constructor
a.     __init__()
3.    Setter to update the value
4.    Getter to return the value
5.    General methods

Example
Create a class Customer having data members as cid, name and balance.
Create a constructor to initialize data in the data members.
Create required setter and getter
Create a method deposit() to deposit some amount
Create a method withdraw() to withdraw some amount
Solution 1: Fixed data
class Customer:
    def __init__(self,cid,name,opamount):
        self.cid=cid
        self.name=name
        self.balance=opamount
    def setName(self,name):
        self.name=name
    def getCid(self):
        return self.cid
    def getName(self):
        return self.name
    def getBalance(self):
        return self.balance
    def deposit(self,amount):
        self.balance=self.balance+amount
    def withdraw(self,amount):
        self.balance=self.balance-amount

c=Customer(134,"Rakesh Kumar",5000)
c.deposit(6000)
c.withdraw(2000)
print("Balance of",c.getName(),"is",c.getBalance())

Solution 2: User data
class Customer:
    def __init__(self,cid,name,opamount):
        self.cid=cid
        self.name=name
        self.balance=opamount
    def setName(self,name):
        self.name=name
    def getCid(self):
        return self.cid
    def getName(self):
        return self.name
    def getBalance(self):
        return self.balance
    def deposit(self,amount):
        self.balance=self.balance+amount
    def withdraw(self,amount):
        self.balance=self.balance-amount

cid=int(input('Customer ID'))
name=input('Customer Name')
balance=float(input('Opening Amount'))
c=Customer(cid,name,balance)
amount=float(input('Add amount'))
c.deposit(amount)
amount=float(input('Withdarw amount'))
c.withdraw(amount)

print("Balance of",c.getName(),"is",c.getBalance())

Using time module

The time module provides the current date and time using time() function The time.time() returns the number of second elapsed from 1/1/1970 12:00 am till current date and time called as ticks >>> import time >>> time.time() 1522211915.914467 We can also convert these ticks into actual date and time using function time.localtime() >>> time.localtime(time.time()) time.struct_time(tm_year=2018, tm_mon=3, tm_mday=28, tm_hour=10, tm_min=10, tm_sec=0, tm_wday=2, tm_yday=87, tm_isdst=0) It returns a structure having different fields for date and time which we can convert into date or time format >>> t=time.localtime(time.time()) >>> currentdate='%02d-%02d-%d' % (t.tm_mday,t.tm_mon,t.tm_year) >>> currentdate '28-03-2018' >>> currenttime='%02d-%02d-%02d' % (t.tm_hour,t.tm_min,t.tm_sec) >>> currenttime '10-12-05' We can also use this structure inside the functions and ...
