Question

This program is supposed to calculate the number of degrees below 60 on a given day then create a running sum of degrees. count equals the sum of degrees below 60. However, when I run it I get this error:

cool = 60 - temp

TypeError: unsupported operand type(s) for -: ‘int’ and ‘str’

Any ideas on why it’s doing this? Thanks!

def cold_days():

    temp = eval(input("What is the temperature? "))
    count = 0

    if temp < 60:
        while temp !="quit":

            temp = eval(input("What is the temperature? "))
            cool = 60 - temp
            count = count + heat
        print(count)
    else:
        print("you have no cold days")

You need to turn temp into an int:

...

try:
    temp = int(temp)
except TypeError:
    # Handle invalid integer
    print("%s is not a valid integer." % temp)
    sys.exit(1)

...
