Question

Write a Python program that uses while loops to perform the following steps and post the text code. Thanks

a. Prompt the user to input two positive integers (no zero or negative). variables: firstNum and secondNum (firstNum must be less than secondNum). Validate the user's input; prompt the user again if firstNum is not less than secondNum (use while loop).

b. Output all odd numbers between firstNum and secondNum. (use while loop).

c. Output the sum of all even numbers between firstNum and secondNum. (use while loop).

d. Output the sum of the square of the odd numbers between firstNum and secondNum. (use while loop)

Program layout for each step:

#A

while loop

#B

while loop

#C

while loop

#D

while loop

***Allow the user to repeat the program. (requires another while loop).

***Do NOT define any functions.

***Your program output must be exactly the same as the output in the OUTPUT section, except font style.

OUTPUT:

- The bold text is the user's input.

Enter two positive integer numbers.
First number must be less than the second number you enter
Enter numbers: 2 8

Odd integers between 2 and 8 are:
3 5 7

Sum of even integers between 2 and 8 = 20

Sum of the squares of odd integers between 2 and 8 = 83

Enter numbers: 1 9

Odd integers between 1 and 9 are:
1 3 5 7 9

Sum of even integers between 1 and 9 = 20

Sum of the squares of odd integers between 1 and 9 = 165

Note:-

Make your indentation correct before running the code.

Python code for given problem:-

#code starts here

while(1):
firstNum=0
secondNum=0
#A-option
while(1):
print("\n****************************************************************")
print("Enter two positive intiger numbers.")
print("First number must be less than the second number:")
print("Enter numbers:")
firstNum,secondNum=input().split(" ")

#cheack for the string is negative or postive digit or not
if firstNum.lstrip('+-').isdigit() and secondNum.lstrip('+-').isdigit():

#cheack for 1st number is less than 2nd or not
if(int(firstNum) < int(secondNum)):

#cheack for number is positive or not
if(int(firstNum)<0):
print("\nNo negative numbers!")
print("Please try again.")
else:
break
else:
print("\nFirst number must be less than the second number:")
print("Please try again.")
else:
print("\nIncorrect Input.")
print("Please try again.")
print("\nEnter two positive intiger numbers.")
print("First number must be less than the second number:")
print("Enter numbers:")
  
#B-option

#print all the odd digit using modulo operation
first=int(firstNum)
second=int(secondNum)
print("\nOdd integers between "+firstNum+" and "+secondNum+" are:")
while(first<=second):
if first%2 is 1:
print(first,end=" ")
first=first+1

#C-option

#sum all even numbers between given range
