|
|
|
* in Python 1.5.2, was contained in the exceptions.py module. The problem
|

|

|
* By moving the exceptions into C and statically linking, we can guarantee

"Python's standard exception class hierarchy.\n\
|
|
|
|
|
\n\
|
|
|
|
|
Before Python 1.5, the standard exceptions were all simple string objects.\n\
|
|
|
|
|
In Python 1.5, the standard exceptions were converted to classes organized\n\
|
|
|
|
|
into a relatively flat hierarchy. String-based standard exceptions were\n\
|
|
|
|
|
optional, or used as a fallback if some problem occurred while importing\n\
|
|
|
|
|
the exception module. With Python 1.6, optional string-based standard\n\
|
|
|
|
|
exceptions were removed (along with the -X command line flag).\n\
|
|
|
|
|
\n\
|
|
|
|
|
The class exceptions were implemented in such a way as to be almost\n\
|
|
|
|
|
completely backward compatible. Some tricky uses of IOError could\n\
|
|
|
|
|
potentially have broken, but by Python 1.6, all of these should have\n\
|
|
|
|
|
been fixed. As of Python 1.6, the class-based standard exceptions are\n\
|
|
|
|
|
now implemented in C, and are guaranteed to exist in the Python\n\
|
|
|
|
|
interpreter.\n\
|
|
|
|
|
\n\
|
|
|
|
|
Here is a rundown of the class hierarchy. The classes found here are\n\
|
|
|
|
|
inserted into both the exceptions module and the `built-in' module. It is\n\
|
|
|
|
|
recommended that user defined class based exceptions be derived from the\n\
|
2000-07-12 04:02:10 +00:00
|
|
|
|
`Exception' class, although this is currently not enforced.\n"
