Unwanted decimal in Python

Question

I have written a code that will add up the values in a tuple and calculate the average:

def average(values):
    return sum(values[0:]) / len(values[0:])

However, I get an unwanted floating point, like 2.0 instead of 2. How do I eliminate this, but still manage to get the correct average should the average not be an integer?

You mean you want to convert the float to an integer [when it is a whole number](http://stackoverflow.com/questions/21583758/how-to-check-if-a-float-value-is-a-whole-number) or do you want to strip the decimal point and 0 when representing the number (say, when printing or writing it to a file)? — Martijn Pieters, Sep 10 '14 at 16:23
This needs a fix in the code you use to display the numbers, not in the code you use for computation. (Also, the slices are pointless.) — user2357112, Sep 10 '14 at 16:24
I wish to convert the float to an integer when it is a whole number — user4027736, Sep 10 '14 at 16:25
Note that the `[0:]` slices are entirely redundant here; they only serve to create copies of the lists which you then discard again. Your code would perform better if you left those out altogether. — Martijn Pieters, Sep 10 '14 at 16:25
@user4027736: why do you feel you need to have an integer value some of the time though? Is it because you don't want to see the `.0` when you output the number? What is the *reason* you think you need to do this? — Martijn Pieters, Sep 10 '14 at 16:26
To remove the decimal separator and zero, see [Most Pythonic way to print \*at most\* some number of decimal places](http://stackoverflow.com/q/14997799) — Martijn Pieters, Sep 10 '14 at 16:27
@user4027736: so you are doing this *when formatting the number for output*. — Martijn Pieters, Sep 10 '14 at 16:28
Are you saying that 2.1 or even 2.32674673673 is okay, but if its 2.0, you'd rather just have 2? — tdelaney, Sep 10 '14 at 16:34

You may try like this:

if (yournumber).is_integer():
        print int(n)
else 
       print (n)
