Counter

I have been scouring the internet for about and hour trying to

find something about a input counter for python3. If thats a little

vague I am making a averaging calculator for my math class

and I need something that will count the amount of input so I

so I can later divide by that number. (its not finished yet)

#counter = 0

total = 0

number = 0

while number >= 0:
number = float(input (" \n \n \t enter here: "))

total += number

average = total/counter

print (average)

so yeah

You just need to increment your counter variable the same way you are updating your total variable. At least if I am understanding you correctly.

counter += 1
Right after your:
total += number

Wheeee....
python Code:
 Original - python Code
``` def avg_of_inputs():    counter = 0    total = 0    while 1:        number = input("\nInput a number (press enter when done): ")        try:            total += float(number)            counter += 1            print("Total so far: "+str(total))        except ValueError:            if number == "":                print("\n")                break            else:                print("That wasn't a number you dolt!\n")    return total/counter if __name__ == "__main__":    again = "y"             while again == "y":        print ("Your avg is: "+str(avg_of_inputs()))        while 1:            again = input("\nAgain? (y/n): ")            if again in ("y","n"):                break            else:                print("\nThat wasn't an option jackass.\n")
```

If Mekire's program works, and I didn't test it for cases that I thought might work, it requires python version 3.

Here I show a run in python2. Given bad input the program terminates with an exception.
And in python3, with no valid input the program again terminates with an exception.

Yes, otherwise I agree that you'd need to count the data either as Mekire did, or by appending the data to a list. Later you can use len(data), and you'll still have the data for other important statistical tests.

Code:
```\$ python /tmp/p.py

Input a number (press enter when done): x
Traceback (most recent call last):
File "/tmp/p.py", line 21, in <module>
print ("Your avg is: "+str(avg_of_inputs()))
File "/tmp/p.py", line 5, in avg_of_inputs
number = input("\nInput a number (press enter when done): ")
File "<string>", line 1, in <module>
NameError: name 'x' is not defined

\$ python3 /tmp/p.py

Input a number (press enter when done): x
That wasn't a number you dolt!

Input a number (press enter when done):

Traceback (most recent call last):
File "/tmp/p.py", line 21, in <module>
print ("Your avg is: "+str(avg_of_inputs()))
File "/tmp/p.py", line 16, in avg_of_inputs
ZeroDivisionError: division by zero```

He specified 3 within his post so I stuck with that. Changing the inputs to raw_inputs will solve the first incompatibility. Generally I write in 2.7 with aim to run under both. Admittedly I did over look the 'divide by zero' thing though but that is also bullet proofed against easily enough.

b49P23TIvg agrees: So he did. I now see the python3.
