Python Programming

Illustration of Python exception handling: try block with code, except catching specific and generic exceptions, finally block cleanup, and logs showing visual error handling flow.

Tuples are immutable collections (parentheses), fixed-size and hashable for keys; lists are mutable sequences (brackets), variable-length for ordered, changeable elements. Use cases.

Diagram showing ways to iterate over a dictionary: for key in dict, for value in dict.values(), for key,value in dict.items(), enumerate(), dict comprehension and arrow code snippets.

Diagram of a Python dictionary: curly braces containing key:value pairs (e.g. 'name':'Alice', 'age':30), arrows linking keys to values showing mapping, mutability and fast lookup.

Digital checklist interface with a cursor removing items: checked entry dragged toward a trash icon while remaining list items reflow upward, indicating deletion and updated order.

Illustration showing a programmer appending items to a list: a list box receiving new elements via an arrow, with sample code 'my_list.append(item)' and step numbers for beginners

Illustration of a Python list: ordered, mutable sequence in brackets with comma-separated items, zero-based indexes, supports mixed types, slicing, append, insert and remove items.

Illustration showing command-line steps to create a Python virtual environment: terminal with 'python -m venv env', folder tree, activation command and isolated packages. Overview.

Graphic showing how to check Python version: open terminal or cmd, type python --version or python3 --version and press Enter to display the installed Python version and its path..
