Anything can raise MemoryError.
Ok. But I don't think regular application code should catch these.
On converting an 8bit string to an int:
ValueError *only*
Ok.
On converting a Unicode string to an int:
ValueError
UnicodeError (or UnicodeEncodeError, which is a subclass of it)
u = makeUnicodeString() # your choice of function
int(u)
My point is that once you have a valid unicode object, I don't see how calling int(valid_unicode_object) will raise a UnicodeError.
If this is so, then the style should be:
value = expression_to_compute_value
try:
i = int(value)
except ValueError:
# take corrective action
rather than:
try:
i = int(expression_to_compute_value)
except: # Note: calling 'int()' can raise just about anything
# take corrective action
