Python Help: Convert Celsius to Fahrenheit

[TromboneNerd]

Im having trouble with a basic python assignment in one of my classes. Its supposed to ask the user for temperatures in Celsius and convert them to Fahrenheit, which it does fine. The problem is that its also supposed stop asking the user if he gives it 0, which means the end of the list of numbers. My program converts fine, but upon entering 0 it just gives me 32, which means something is wrong with my if statement and its just converting 0 like a normal number. Any help? here is my code.

count = 1
converted = False
while (converted == False):

Celsius = raw_input("Temperature number " + str(count) + " to be converted?: ")

if (Celsius.rstrip() == 0):
converted = True​

Celsius = int(Celsius.rstrip()) * 1.8 + 32
print (Celsius)
count = count + 1​

I also just realized this is in the wrong forum. If a mod would kindly delete it ill just re-post in the correct forum. #apologies

note that Celsius.rstrip() is a string
int(Celsius.rstrip()) is an integer

I took your code and put it in [ code ] tags.

count = 1
converted = [COLOR="DarkOrchid"]False[/COLOR]
[COLOR="Orange"]while[/COLOR](converted == [COLOR="DarkOrchid"]False[/COLOR]):
    Celsius = [COLOR="DarkOrchid"]raw_input[/COLOR]([COLOR="SeaGreen"]"Temperature number "[/COLOR] + [COLOR="DarkOrchid"]str[/COLOR](count) + [COLOR="SeaGreen"]" to be converted?: "[/COLOR])
    [COLOR="Orange"]if[/COLOR] (Celsius.rstrip() == 0):
        converted = [COLOR="DarkOrchid"]True[/COLOR]
    Celsius = [COLOR="DarkOrchid"]int[/COLOR](Celsius.rstrip()) * 1.8 + 32
    [COLOR="DarkOrchid"]print[/COLOR](Celsius)
    count = count + 1

You may want to refactor a bit, as there are some things you can do to make the code more "Pythonic". For your original question, try

[COLOR="Orange"]if[/COLOR] Celsius.rstrip() == "0":

as your test.

First, I would suggest using the built-in function input() instead of raw_input() as it will automatically convert the user's input to a number. Additionally, you should be using the integer 0 in your if statement instead of the string "0". This is because when you use the rstrip() function, it will remove any trailing whitespace, so the input of 0 will become an empty string, which will not equal 0. So your if statement should be if (Celsius == 0). This should solve the issue and properly stop the loop when the user enters 0.
