Stella (previously) sends us a much elided snippet. The original code is several thousand lines contained in a single try block. But the WTF is pretty clear without seeing all of that:
try:
# the whole business logic without any exception handling
except:
print("Fudge")
They didn't really say fudge of course, but we mostly try to keep profanity off our main page. Mostly. In any case, when your operation fails someplace in the middle and you have no idea where, why, or how: "Oh, fudge!" is the appropriate expression.
