That is absolutely not a Python error message.

There are two sorts of Python error messages: tracebacks, and segmentation
faults. You should never see  segmentation fault (if you do, it is a bug or
corruption in the Python interpreter) but if you do, there may not even be
message aside from "Segmentation fault". So forget all about them.

The only sort of Python error message you are likely to see is a traceback,
which looks like this:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: not enough values to unpack (expected 2, got 1)


There may be more lines between the "Traceback" line and the last line,
which will be the actual error. It may not be ValueError, it could be
TypeError, AttributeError, IndexError, or many other things.

What happens if you *don't* run the program under PyScripter?

It looks to me that PyScripter is trying to be "helpful" by hiding the
actual error message from you, and perhaps showing you some random
diagnostic, or the line of code that failed.

Of course that's not helpful at all. See if you can run the script without
involving PyScripter. The easiest way is to enter the following at a
terminal or console:

python myscript.py

Replace the "myscript.py" with the actual name of your Python .py file.

Who told you this? I'm pretty sure they're wrong.

Unless they are going by more information than you've told us.
