I was conducting Mean Coodinates process functions with weighted fields when I began faces ZeroDivision errors in some processes.

The Shapefile Data has been joined together with imported Spreadsheet data.

I have to run this simulation multiple times and about 70% of the times it has worked without errors while it is giving the following error with the combination of particular shapefiles with certain weighted means.

the error is:

Uncaught error while executing algorithm

Traceback (most recent call last):

cx = values[0] / values[2]

ZeroDivisionError: float division by zero

What is the issue and how can it be solved?

    The issues seems to be that you can't divide by 0 eg. 3.4/0. This link reference "exception ZeroDivisionError" indicates "Raised when the second argument of a division or modulo operation is zero". Somewhere in your values for "values[2]" you have zeros present.

  • Try to add a print (values[2]) ; assert values[2] != 0 at line 118. As some point, this assertion will probably fail.

  • Maybe there is no data in tour variable, check with a print or something else

if values[2] != 0:
    cx = values[0] / values[2]
else:
    cx = 0
