Python for everybody assignment 3.3

Why wouldn't my for loop work? If I put in 0.85 for grade score it'd print out F and error message instead of B. Why is this?

• What makes you think you need a loop? You should try without it. –  quamrana Commented May 25, 2022 at 20:55
• agred, the range(0, 1) is probably redundant –  Wizard.Ritvik Commented May 25, 2022 at 20:56
• 3 It's not clear what for fg in range(0,1): is supposed to do; you're completely overwriting and replacing fg with the integer value 0 . It seems that you don't know or understand what range() does. –  Random Davis Commented May 25, 2022 at 20:57
• Add some prints, do some debug. Your loop runs once and sets fg to 0 so the else always runs –  Tomerikoo Commented May 25, 2022 at 20:57
• 3 @rv.kvetch what's the point of looping at all? It seems like only the if statement is needed –  Random Davis Commented May 25, 2022 at 20:57

You are misusing the range() function. range() is used to iterate over multiple values, not to validate if a number is in a range. You should instead check that fg greater than or equal to 0, or less than or equal to 1. Like this:

• 1 or maybe: if not 0 <= fg <= 1: –  Wizard.Ritvik Commented May 25, 2022 at 21:02
• " range() is used to iterate over multiple values, not to validate if a number is in a range" - depends what type of range. It wouldn't work in this case with floats, but you can totally do if value in range(2, 6) to check for natural numbers –  Tomerikoo Commented May 25, 2022 at 21:05

you are doing this for one time you dont need to use a loop you can do this

You do not need to use for operator neither range. The simplest solution is:

grade = input("Enter number:") try: grade = float(grade) except: grade = -1

I have written this code but in case of largest and smallest number it is showing done. How to fix this

Sorry, something went wrong.

newbie-Ds commented Jun 7, 2022 • edited Loading

I think it's because you put while True: number = input("Enter a Number: ") largest = number ------------------ if you enter 'done', here returns to 'done' smallest = number ------------------ if you enter 'done', here returns to 'done'

Let's try if this works.

kholoud24 commented Aug 5, 2022

maxum = False minum = False while True: input_value = input("enter number\n") if input_value == 'done': break try: input_value = int(input_value) if not maxum or maxum < input_value: maxum = input_value

print('max is ', maxum, 'min is', minum)

Minting-2022 commented Nov 9, 2022

When I enter a number,it just shows the'Invalid input',how can I fix it? count=0 total=0 largest=None smallest=None

while True: number=input("Enter a number: ") if number=='done': break try: fnum=float(number) if number=='done': break if largest<=fnum: largest=fnum if smallest>=fnum: smallest=fnum except: print("Invalid input") continue total=total+fnum count=count+1

print(total,count,largest,smallest)

gaurvimadan commented Nov 13, 2022 • edited Loading

I guess the problem is that you have used below mentioned if statement twice. It shouldn't be added in try statement. if number=='done': break

I tried solving the question in the below mentioned way, maybe it can help you.

I did mine like this, I hope it helps...
