In collections, you’ll find the ChainMap class, which allows you to create a dictionary-like object by combining multiple existing dictionaries. With ChainMap, you can iterate through several dictionaries as if they were a single one.In itertools, you’ll find a function called chain() that ...
Class (a.k.a. "type") A way to couple data and functionality. Classes store data within each instance of that class (within the attributes). You can make a new class instance by calling the class. The functionality of a class comes from its methods. The word "type" is a synonym for...
The iterator returned by zip() iterates over these tuples.The map() built-in function is another “iterator operator” that, in its simplest form, applies a single-parameter function to each element of an iterable one element at a time:...
>>> o1.method <bound method SomeClass.method of <__main__.SomeClass object at ...>>Accessing the attribute multiple times creates a method object every time! Therefore o1.method is o1.method is never truthy. Accessing functions as class attributes (as opposed to instance) does not ...
# Note that a tuple of length one has to have a comma after the last element but# tuples of other lengths, even zero, do not.type((1))# => <class 'int'>type((1,))# => <class 'tuple'>type(())# => <class 'tuple'> ...

This is a useful idiom: pass a generator to the list() function, and it will iterate through the entire generator (just like the for loop) and return a list of all the values. The for loop will automatically call the next() function to get values from the generator and assign them to...
In the is_chain_valid() method of the Blockchain class, iterate through all blocks in the blockchain and check if their hashes are valid and if they are linked together correctly (i.e., each block’s previous_hash attribute should equal the hash of the previous block). With these steps...
