However, the implementation has been changed. Dictionary, list, and set comprehensions no longer rely on functions in the background. Instead, all comprehensions are now compiled directly within the context of the current function. The comprehension’s bytecode is contained within an individual code ...
Output: >>> WTF() is WTF() I I D D False >>> id(WTF()) == id(WTF()) I D I D True As you may observe, the order in which the objects are destroyed is what made all the difference here.▶ Disorder within order *from collections import OrderedDict dictionary = dict() dictio...
Loops can iterate over a tuple in the same way as a list. my_tuple = (1, "apple", 3.14) for item in my_tuple: print(item) 4. Dictionaries: Dictionaries in Python are unordered collections of key-value pairs. Looping over a dictionary can be done in several ways - by iterating ...

Dictionary comprehensions: {k: v for k, v in stuff} means the same thing as dict(stuff) but is more flexible. (This is PEP 0274 vindicated. :-) Set literals, e.g. {1, 2}. Note that {} is an empty dictionary; use set() for an empty set. Set comprehensions are also supported...

Uniqueness of keys in a Python dictionary is by equivalence, not identity. So even though 5, 5.0, and 5 + 0j are distinct objects of different types, since they're equal, they can't both be in the same dict (or set). As soon as you insert any one of them, attempting to look ...
