Have an assignment of finding average and maximum rainfall in file \"BoulderWeatherData.csv\". Have found the average using this code:

    rain = open(\"BoulderW         


        

Answer 1

You're already accumulating total across loop iterations.

To keep track of a maxvalue, it's basically the same thing, except instead of adding you're maxing:

total = 0
maxvalue = 0

for line in data:
    r = line.split(",")
    value = float(r[4])
    total = total + value
    maxvalue = max(maxvalue, value)

print(total)
print(maxvalue)

Or, if you don't want to use the max function:

for line in data:
    r = line.split(",")
    value = float(r[4])
    total = total + value
    if value > maxvalue:
        maxvalue = value
