Acquaintance python - Notes

Note the code division multi-line and single-line comments, with a single line comment #, the comment may be multi-line three pairs of double quotes“”” “””

Here for everyone to see the comment section of the standard code, ignore the meaning of the code

def subclass_exception(name, parents, module, attached_to=None):
"""
Create exception subclass. Used by ModelBase below.
If 'attached_to' is supplied, the exception will be created in a way that
allows it to be pickled, assuming the returned exception class will be added
as an attribute to the 'attached_to' class.
"""
class_dict = {'__module__': module}
if attached_to is not None:
def __reduce__(self):
# Exceptions are special - they've got state that isn't
# in self.__dict__. We assume it is all in self.args.
return (unpickle_inner_exception, (attached_to, name), self.args)

Code comments principles:

1. Not all the code to add comments, or just need to find it difficult to understand the important part to add a comment to their own
2. Comments can either Chinese or English, but never Pinyin oh
3. Not only to give their comments to see, but also to others, so please write carefully
