# Python solved programs with output and explanation

Python is a general-purpose, high-level, simple but effective object-oriented programming approach based, and an interpreted programming language. It’s very easy to learn (due to emphasized code readability) and powerful programming language.

This is the best way to learn Python programming by practicing the **Python programs**. This section contains **Python solved programs** on various topics such as basic programs, conditional & control statement-based programs, arrays programs, matrices programs, string programs, lists programs, dictionaries, file handling, data structure programs, etc.
