This is a very strange exception raised from somewhere in our program.
I have no idea how this happen. And don't know how to reproduce. It
just occurs from time to time.
Can anyone give me some suggestion to fix this?
Thanks.

If it's raised from "somewhere in your program" the first this to do is
disable the except clause that is apparently stopping you from getting a
full traceback, then post that traceback with an appropriate code snippet.
People on this list are good at guessing, but it's better to give then
some hard information to work with.
Otherwise you are calling the shop (garage?) and saying "My car doesn't
work, can you tell me how to fix it, please?"

Maybe different `Decimal`\s? Here's how to reproduce such a traceback:
In [20]: from decimal import Decimal
In [21]: a = Decimal()
In [22]: class Decimal(object) :
....: pass
....:
In [23]: b = Decimal()
In [24]: a - b
<type 'exceptions.Typ eError' Traceback (most recent call last)
/home/bj/<ipython consolein <module>()
<type 'exceptions.Typ eError'>: unsupported operand type(s) for -: 'Decimal' and 'Decimal'
Ciao,

traceback:
<snip>
Or even just one Decimal type but not one which supports subtraction:
>>class Decimal(object) :
pass
>>a = Decimal()
b = Decimal()
a-b
Traceback (most recent call last):
File "<pyshell#4 >", line 1, in <module>
a-b
TypeError: unsupported operand type(s) for -: 'Decimal' and 'Decimal'
Another option of course is that Decimal() did support substraction but
someone deleted it:
>>from decimal import Decimal
del Decimal.__sub__
Decimal()-Decimal()
Traceback (most recent call last):
File "<pyshell#1 5>", line 1, in <module>
Decimal()-Decimal()
TypeError: unsupported operand type(s) for -: 'Decimal' and 'Decimal'
Thanks. I think I have some direction to do logging, to get more
information about this problem.
It seems that I don't get used to dynamic language yet.

Perhaps I don't understand what you are doing here, but on line 22 you
overload Decimal. If you just have
a = Decimal()
b = Decimal()
print a-b yields 0. decimal.Decimal () can be subtracted from
decimal.Decimal (). decimal.Decimal () can not be subtracted from class
Decimal(object) . I would assume that they are different types. Using
the original code, print type(a), type(b).

In the utter absence of any clues from the OP, Marc was demonstrating
one possible way that the puzzling [Can't subtract one Decimal
instance from another???] error message could have been caused.

Ah yes. Until this is no longer true, "In the utter absence of any
clues from the OP", we can do no more. My appologies to Marc for
misinterpretati on. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I am trying to undestand "Type Conversions" from K&R book.I am not
