Python 'in' operator

The 'in' operator in Python is used to check if a specific value or element is present within a sequence (like strings, lists, or tuples) or a dictionary.

Python '#' symbol

The '#' symbol in Python acts as a comment marker. Anything written after '#' on a line is ignored by the Python interpreter, making it useful for adding explanatory notes to your code.

Python '**' operator

The double asterisk operator () in Python is used for exponentiation, which means raising a number to a certain power. For example, 23 calculates 2 raised to the power of 3, resulting in 8 (2 * 2 * 2).

Duplicate Keys in Python Dictionaries

In Python dictionaries, duplicate keys are not allowed. If you assign a value to an existing key, the latest assignment overwrites the previous one. The dictionary will only hold the last assignment, so in the example provided, the final value assigned to the key is the one retained.
