Question

PLEASE DO BOTH OF THESE IN PYTHON!!! AND MAKE SURE THAT I CAN COPY THE CODE.

1.) Exercise #1: Design and implement a program (name it PrintSum) that prompts the user for an integer values between 1 and 100. The program then uses a while loop to determine and print out the sum of all values between 1 and the entered value. The program rejects invalid input values with proper message such “Invalid Input. Try again.” Document your code and properly label the input prompt and the outputs as shown below.

Sample run 1:

You entered:    10

Sum of values: 55

Sample run 2:

You entered:    120

Invalid input. Try again.

Sample run 3:

You entered:    20

Sum of values: 210

2.) Exercise #2: Design and implement a programming (name it EvenOdd) that uses a while loop to determine and print out all even numbers between 50 and 100 on a single line, separated by commas. Then another while loop in the same program to print out all odd numbers between 50 and 100 on a new line, separated by commas. Document your code and properly label the outputs as shown below.

Even numbers between 50 and 100: 50, 52, 54, 56, 58, 60, 62, 64, …

Odd numbers between 50 and 100: 51, 53, 55, 57, 59, 61, 63, 65, …

Answer 1

1) 
# Take input
value = int(input('You entered: '))
sum = 0

# Check if value is valid
# If yes, iterate a loop and add 1 to value to sum
# Print sum
# Else, print message
if 1 <= value <= 100:
    for i in range(1, value + 1):
        sum += i
    print('Sum of values:', sum)
else:
    print('Invalid input. Try again.')

2)

value = 50

print('Even numbers between 50 and 100: ', end="")
# Iterate loop till value is 100
# If value is divisible by 2, it's even
# If value is the last or second last number, we don't want to print comma after that
# end=", " separates values by a comma
# Increment value 1
while value <= 100:
    if value % 2 == 0:
        if value in [99, 100]:
            print(value)
        else:
            print(value, end=", ")
    value += 1

# Re-set value to 50
value = 50
print('Odd numbers between 50 and 100: ', end="")
# Same process for odd number
# Only when value is not divisible by2 , it's an odd number
while value <= 100:
    if value % 2 != 0:
        if value in [99, 100]:
            print(value)
        else:
            print(value, end=", ")
    value += 1
