python-stack-push-pop

May 20, 2026 – Present

A simple Python program demonstrating Stack operations using lists. Includes Push operation to insert elements into the stack and Pop operation to remove elements following the LIFO (Last In First Out) principle. Useful for beginners learning data structures in Python.

python-machine-parts-filter

May 18, 2026 – Present

A Python program that stores machine parts with their costs and dimensions, then filters parts using “in” and “not in” operators based on conditions such as cost below a specified value and dimensions within a given range. Useful for learning lists and membership operators.

python-student-merit-list

May 17, 2026 – Present
