Question

When I try to run this code, I get incorrect maximums and minimums. Could anyone tell me how I can fix it? I am not allowed to use ‘max’ and ‘min’.

UPDATE: I have updated the code and it still doesn’t work properly.
UPDATE 2: The code works now! Thank you so much guys!

minimum=float('inf')
maximum=None
count=0
total=0
number=input ("Please enter the amount of numbers you wish to categorize: ")
while True:

    num = input("Enter a number: ")
    count+=1
    total+=num

    if num is None or num < minimum:
        minimum = num

    if num is None or num > maximum:
        maximum = num
    if count == number:
        break           

print "The average of your numbers is ", round ((total / count),2),"."
print 'The largest number is:', maximum,"."
print 'The smallest number is:', minimum,"."

Answer 1

Your initial values and conditions for minimum and maximum are incorrect.

minimum = None
maximum = None
 ...
    if minimum is None or num < minimum:
        minimum = num

    if maximum is None or num > maximum:
        maximum = num
...

You could also fix this by checking if count equals 1 instead of identity to None.
