11 conditional operations in python

 1. Using if, elif and else we can perform conditional operations

2. Using conditioanl operations we can execute a block of code based on condition


# Below are the python operators to perform conditional operations

    1. Arthmetic operators(+,-,*,%,/,//)

        1. Uesd to do addition and substraction operations

    2. Assignment operators(=,+=,-=,*=,%=,/+,//+)

        1. Used to assign value to variable

    3. Comparison operators(==,!=,>,>=,<,<=)

        1. These operators compare the values on either sides of them and decide the relation among them. 

            They are also called Relational operators.

    4. Logical operators(and,or,not)

        1. Using logical operations we can execute a block of code based on multiple condition.

    5. Membership operators(in,not in)

        1. Using member ship operations we can find a value in list and sub string in a string

    6. Identity operators(is,is not)

        1. Using identity operators we can check memory location of objects


1) simple if statement

#name = 78

#if name <= 78:

 #          name //= 10

  #         print(' Name is :', name)

    

if name = 99:

          name // = 10

          print(' Name is :', name)


# Give nuber is even or not

n = int(input("enter the number?"))  

if n%2 == 0:  

    print("Number is even")  



#Program to print the largest of the three numbers


a = int(input("Enter a? "));  

b = int(input("Enter b? "));  

c = int(input("Enter c? "));  

if a>b and a>c:  

    print("a is largest");  

if b>a and b>c:  

    print("b is largest");  

if c>a and c>b:  

    print("c is largest");  


2) if else statement

name = 'uma'


if name == 'mahesh':

    name += 'uma'

    print(' Name is :', name)

else:

    print(name)

sal = 2344

print(sal)



#Program to check whether a number is even or not.

n = int(input("enter the number?"))  

if n%2 == 0:  

    print("Number is even")  

else:  

    print("Number is odd")  



#to check whether a person is eligible to vote or not.

age = int (input("Enter your age? "))  

if age>=18:  

    print("You are eligible to vote !!");  

else:  

    print("Sorry! you have to wait !!");  


3) if else comparision


# number equal to 10,20 or 100

n = int(input("Enter the number?"))  

if n==10:  

    print("number is equals to 10")  

elif n==50:  

    print("number is equal to 20");  

elif n==100:  

    print("number is equal to 100");  

else:  

    print("number is not equal to 10, 20 or 100");  



# Identify grade of students

marks = int(input("Enter the marks? "))  

if marks > 60 and marks <= 100:  

   print("Congrats ! first class ...")  

elif marks > 50 and marks <= 60:  

   print("second class.")  

elif marks > 40 and marks <= 50:  

   print("Third class")  

elif (marks > 35 and marks <= 40):  

   print("pass")  

else:  

   print("Sorry you are fail ?")  



n = 54

if n == 20:

    print(' If block ')

elif n != 54:

 print(' First elif ')

elif n > 30:

       print('Second elif')

elif n >= 11:

    print('Third elif')

elif n < 2:

    print(' Forth elif')

else:

    print(' Else block')

4) logical operators
'''
  1. Using logical operations we can execute a block of code based on multiple condition.
'''

sal  = 4000
dname = 'IT'

#if sal >= 50000 and dname == 'IT' : print(sal + 2500)

#if sal >= 50000 or dname == 'IT' : print(sal + 2500)

if not sal != 4000: print('  NOT  ')

5) membership function
'''
1. Using member ship operations we can find a value in list and
 sub string in a string
2. We can't perform membership opertion on number data type.
'''

#name = 'umamahesh'
#if 'ma' in name: print('IN')
#if 'k' not in name: print('NOT IN')

names = ['pratap','ganesh','kumar','balu']
#t = ('sriram','ganesh','kumar','balu')
#s = {'sriram','ganesh','kumar','balu'}
if 'pratap' in names:  print(names)

#d = {'name':3, 'eid':56, 99:89, '55':33}
#if 99 in d: print(' Dictionary')


#n = 8976
#if 97 in n: print(n)

6) identity operator
'''
1. Using identity operators we can check memory location of objects.
'''

#a = 10
#b = 10
#c = a
#if a is c : print(' IS ')


l = [1,2,3]
l2 = l
print(' L id is  : ', id(l))
print(' L2 id is : ', id(l2))

if l is l2 : print(' OK ')

  Python Programming tutorial provides basic and advanced concepts of Python programming. This Python programming  tutorial is designed for beginners and professionals.  Python is a simple, general purpose, high level, and object-oriented programming language. In this we have different chapter and their concepts Python Programming : tokens, literals, identifiers, keywords, special symbols and operators; fundamental data types, expressions, type conversions, handling Input and output in Python. Selection Statements : if statement, if-else statement, if-elif-else statement, nested-if statement.  Iterative Statements : while loop, for loop, break statement, continue statement, pass and else statements used with loops. Sequences : Lists and operations - creating, inserting elements, updating elements, deleting elements, searching and sorting, list comprehensions, nested lists; tuples - creating, searching and sorting, nested tuples;  strings - Initializing a string and string opera

16 file handling in python

 1. Using file handling we can do file operations # How to open a file in python ? 1. We can open a file two ways in python      1. open()     2. With open() # OPEN 1. Using open we can open only one file at a time and we have to close a file explicity # WITH OPEN  1. Using with open we can open multiple files at a time and no need to close files explicity # File Open Modes In Python r    ==>     It opens a file for read only. w    ==>     It allows write-level access to a file. If the file already exists, then it’ll get overwritten. It’ll create a new file if the same doesn’t exist. a    ==>     It opens the file in append mode. a+   ==>     It opens a file FOR append AND read rb   ==>     It opens a binary file for read 1)  Read file fh = open('names.txt', 'r') ## To open a file from another path #fw = open(r'C:\Users\smellamput001\Desktop\BACKUP_EPRO\RRR.txt', 'r') ## Using read we can read entire file data and return in string format f

4 Tuple data types

 ''' 1. Tuple is used to store multiple values and  we can do operation on each value based on index. 2. Tuple is a read only object,  we can't do update,insert and delete operations. 3. Using parentheses "()" we can create a tuple 4. tuple is a immutable object 5. To store sensitive data we use tuple. ''' # To create a tuple names = ('umamahesh','kumar','balu','ram', 567, 99.9) # Tuple doesn't support for item deltion and update names[3] = 'ok' del names[3] # To print particular value based on index print(names[4]) print(names[-1]) # To delete a total tuple del names
