Program to check the authentication of username and password

by

In this python if else program, we will check authentication of username and password. The name and password of the user should be the same to be valid

Steps to solve the program
  1. Take Username and password as input through the user.
  2. If the username and password is equal then it is authenticate.
  3. Use if-else statement for this purpose.
  4. Print the output.
				
					# Take username and password as input through the user
name = input("Enter name: ")
password = input("Enter password: ")
# Authenticate username and password
if name == password:
# Print output
    print("It is valid")
else:
# Print output
    print("It is not valid")

Output :

				
					Enter name: sanket
Enter password: 1234
It is not valid

Check a number is part of the Fibonacci series

by

In this Python if-else program, we will check whether a given number is part of the Fibonacci series.

What is the Fibonacci series?
The Fibonacci sequence is a set of integers (the Fibonacci numbers) that starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers.

Steps to solve the program

  1. Take a list of all the numbers in a Fibonacci series from 0-10.
  2. Take a number as input through the user.
  3. Use if-else statement to check whether the given number is a part of the Fibonacci series or not.
  4. Print the output.
				
					# Fibonacci series
fib = [0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
# Take input through the user
num = int(input("Enter a number: "))
# Check for number in fibonacci series
if num in fib:
    # Print output
    print("It is a part of the series :", num)
else:
   # Print output
    print("It is not a part of the series :", num)

Output :

				
					Enter a number: 22
It is not a part of the series

by

In this Python if-else program, we will check whether the given number is odd or even.

Odd number:
Odd numbers are those numbers that cannot be divided into two equal parts.

Even number:
even numbers are those numbers that can be divided into two equal parts.

Steps to solve the program

  1. Take the number as input through the user.
  2. Using an if-else statement check whether the given number is odd or even.
  3. If the number is divisible by 2 then it is even else odd.
  4. Print respective output.
				
					# Take input through the user
num =  int(input("Enter a number: "))
# Check for odd and even number
if num%2 == 0:
# Print output
    print("It is an even number")
else:
#Print output
    print("It is an odd number")

Output :

				
					Enter a number: 23
It is an odd number

Program to check whether the number is a prime number.

by

In this python if else program, we will check whether an number is a prime number or not.

A prime number is a whole number greater than 1 that cannot be exactly divided by any whole number other than itself and 1.

Hint:
Use for loop with the range function and use if statement inside the loop

Steps to solve the program
  1. Take a number as input through the user and create a variable count and assign its value equal to 0.
  2. Use for loop with the range function to iterate over 2 to the given number.
  3. During the iteration check if any number divided the given number then add 1 to the count variable using if-else statement.
  4. If value of the count variable is greater then 0 then it is not a prime number.
  5. Print the respective output.
				
					# Take input through the user
num =  int(input("Enter a number: "))
# Create count variable
count = 0
# Iterate over numbers
for i in range(2,num):
# Check for division
    if num%i == 0:
    # Add 1 to the count variable
        count += 1
# Check for prime number        
if count > 0:
# Print output
    print("It is not a prime number")
else:
#Print output
    print("It is a prime number")

Output :

				
					Enter a number: 59
It is a prime number

Python program to print the square of the number

by

In this python if else program, we will print the square of the number if it is divided by a certain number ( 11 ). To find the square of a number we need to multiply that number by itself or we can use power operator to get square of the value. e.g. var1**2

Hint:
Use ** to get the square.

Steps to solve the program
  1. Take a number as input through the user.
  2. Use an if-else statement to check whether the given number is divisible by 11 or not.
  3. If yes then print its square.
  4. Else print False.
				
					# Take input through the user
num =  int(input("Enter a number: "))
# Check for division
if num%11 == 0:
    # Print output
    print(num**2)
else:
    # Print output
    print("Number is not divisible by 11")

Output :

				
					Enter a number: 22
484
				
			
				
					Enter a number: 31
Number is not divisible by 11

Hint:
Use AND(&) with if-else statement.

Steps to solve the program
  1. Take a number as input through the user.
  2. Use if-else statements to check whether the given number is divisible by 3 and 5 also.
  3. If yes then then print True, if not then print False.
				
					# Take input through the user

In this python if else program, we will assign grades to each student as per total marks scored.

Condition for grades:
Marks less than 40: Fail
Marks between 40-50: Grade C
Marks between 51-60: Grade B
Marks between 61-70: Grade A
Marks between 71-80: Grade A+
