TypeError：“ int”对象不是具有循环的Python迭代问题（入门）

Question

Ignoring any current issues with avsterr, I want to call the defined function avsterr to run x amount of times where x is length of my list(). barcodeCounter defines the max length of the list. I am not sure how to write the syntax and what type of loop I should use (for, while, if).

for _ in barcodeCounter: (av,st) = avsterr(topr[barcodeCounter],toprseq[barcodeCounter]) gives me "TypeError: 'int' object is not iterable"

def avsterr(x,z):
        ave = len(x)/len(z)
        ssq = 0.0
        for y in x:
                ssq += (y-ave)*(y-ave)
        var = ssq / (len(x)-1)        sdev = math.sqrt(var)
        stderr = sdev / math.sqrt(len(x))
        return (ave,stderr)

I hope this is enough info. I appreciate any explanations you can give to help me better understand python.

Answer 1

Use range() method. You can iterate an int in this way:

In [1]: for y in range(10):
   ...:     print y
   ...:     
0
1
2
3
4
