Question

I have to write a program that accepts a sequence of average daily temperatures and put those temperatures into a list, but I can’t figure out how. What I tried below does not work. Instead of giving me a list it just gives me the last input.

def main():
    #create a list to store the temperatures.
    tempList = []
    while True:
        dailyTemp = raw_input(
            "Enter average daily temperature or -100 to quit: ")

        # assign dailyTemo to tempList list
        tempList = [dailyTemp]

        print tempList

        if dailyTemp == '-100':
           break

main()

Answer 1

To append to a list, you have to do templist.append('thingtoappend').

In your case, you’d want something like this:

tempList = []
while True:
    dailyTemp = raw_input("Enter average daily temperature or -100 to quit: ")
    tempList = tempList.append(dailyTemp)

What the code that you posted does instead is, it says that the temperature that the user entered, is the list – so each time they enter a new temperature, it replaces the last one they entered.
