Python’s built-in hashing function,hash(), returns an integer value representing the input object. The code then uses the resulting hash value to determine the object’s location in the hash table. This hash table is a data structure that implements dictionaries and sets. The code below demo...
The URL scheme supports a new?exec=...parameter that allows creating URLs that contain encoded Python source code. It is also possible to create an “exec” URL directly from a script in the editor (“Wrench” -> Share -> Create Executable URL). ...
