Python loop help

Expand Post »

We are creating a loop in my CSET class and I am stuck. This is the original script I created:

python Syntax (Toggle Plain Text)
#This is a game character health simulator
health = int(input("What is your characters health?"))
if health <0:
    print("Dead")
elif health >=0 and health <100:
    print("Weak")
elif health >100 and health <=500:
    print("Healthy")
elif health >500:
    print("Strong!")
input("Press Enter")
#This is a game character health simulator
health = int(input("What is your characters health?"))
if health <0:
    print("Dead")
elif health >=0 and health <100:
    print("Weak")
elif health >100 and health <=500:
    print("Healthy")
elif health >500:
    print("Strong!")
input("Press Enter")

We are supposed to Use a while loop to let user repeat steps 2 . Use number -1 (negative 1) to stop the loop. This is what I have come up with but I can't get it to work.

python Syntax (Toggle Plain Text)
#This is a game character health simulator
health = int(input("What is your characters health?"))
while health != -1:
    if health <=0:
        print("Dead")
    elif health >=0 and health <100:
        print("Weak")
    elif health >100 and health <=500:
        print("Healthy")
    elif health >500:
        print("Strong!")
input("Press Enter")
#This is a game character health simulator
health = int(input("What is your characters health?"))
while health != -1:
    if health <=0:
        print("Dead")
    elif health >=0 and health <100:
        print("Weak")
    elif health >100 and health <=500:
        print("Healthy")
    elif health >500:
        print("Strong!")
input("Press Enter")

Any help is greatly apperciated.

Re: Python loop help

Maybe this will help you see what you have done wrong:

Python Syntax (Toggle Plain Text)
>>> myvar = 0
>>> while myvar != 8:
	myvar = int(input("input 8 to stop the loop: "))
 
 
input 8 to stop the loop: 4
input 8 to stop the loop: 23949
input 8 to stop the loop: 8
>>>
>>> myvar = 0
>>> while myvar != 8:
	myvar = int(input("input 8 to stop the loop: "))

	
input 8 to stop the loop: 4
input 8 to stop the loop: 23949
input 8 to stop the loop: 8
>>>

Re: Python loop help

Please use code tags when posting code

You will need to re-input the health inside the loop so that it will ask the user for the health again. I suspect the current version outputs the 'health status' waits for enter and then outputs the same status again.

Re: Python loop help

It is much simpler and more readable if you set up your while loop this way ...

python Syntax (Toggle Plain Text)
# This is a game character health simulator
# give the user instructions
print("Character health can be from 0 to 600+ (-1 exits the loop)")
while True:
    health = int(input("What is your characters health?"))
    if health == -1:
        break  # exits the while loop
    if health <= 0:
        print("Dead")
    elif health >= 0 and health < 100:
        print("Weak")
    elif health > 100 and health <= 500:
        print("Healthy")
    elif health > 500:
        print("Strong!")
 
input("Press Enter")
# This is a game character health simulator
# give the user instructions
print("Character health can be from 0 to 600+ (-1 exits the loop)")
while True:
    health = int(input("What is your characters health?"))
    if health == -1:
        break  # exits the while loop
    if health <= 0:
        print("Dead")
    elif health >= 0 and health < 100:
        print("Weak")
    elif health > 100 and health <= 500:
        print("Healthy")
    elif health > 500:
        print("Strong!")

input("Press Enter")

Simply an endless loop with an exit condition.

Note: This is Python3 code
