Version History: Version 1.1 corrects two bugs in version 1.0: First, it leaked memory: in Proc1(), NextRecord ends up having a pointer to itself. I have corrected this by zapping NextRecord.PtrComp at the end of Proc1(). Second, Proc3() used the operator != to compare a record ...
Python does this in constant time without having to scan through every item by using hash functions. When Python looks up a key foo in a dict, it first computes hash(foo) (which runs in constant-time). Since in Python it is required that objects that compare equal also have the same ...
The fact that None is a singleton allows you to compare for None using the is keyword, like you did when creating decorators with optional arguments: Python if _func is None: return decorator_name else: return decorator_name(_func) Using is returns True only for objects that are the ...
You can also cross compare the results with another version ofuncompyle6since there are sometimes regressions in decompiling specific bytecode as the overall quality improves. For Python 3.7 and 3.8, the code indecompyle3is generally better. ...
