Question 97

A Python program is shown below:

reading = float(input("Enter pressure (bar): "))
if reading > 2.5:
    print("WARNING")
else:
    print("OK")

The program needs to be modified so that it repeats exactly eight times using definite (count-controlled) iteration. Select the option that accomplishes this correctly.

A
count = 0
while count < 8:
    reading = float(input("Enter pressure (bar): "))
    if reading > 2.5:
        print("WARNING")
    else:
        print("OK")
    count = count + 1
B
for count in range(0, 8):
    reading = float(input("Enter pressure (bar): "))
    if reading > 2.5:
        print("WARNING")
    else:
        print("OK")
C
for count in range(0, 9):
    reading = float(input("Enter pressure (bar): "))
    if reading > 2.5:
        print("WARNING")
    else:
        print("OK")
D
count = 1
while count <= 8:
    reading = float(input("Enter pressure (bar): "))
    if reading > 2.5:
        print("WARNING")
    else:
        print("OK")
    count = count + 1
