📄️ A
This code is a collection of four programs - one that performs mathematical operations, one that manipulates strings, one that manipulates lists, and one that manipulates dictionaries. The programs demonstrate various operations such as addition, subtraction, multiplication, division, printing, appending, popping, deleting, and modifying elements in a list and dictionary.
📄️ B
This code demonstrates a basic implementation of a stack data structure using Python. A stack follows the last-in, first-out (LIFO) principle, where elements are added and removed from the top of the stack.
