Example: number = 100 print ( type (number)) # Output: <class 'int'>  ->Float: For decimal numbers (e.g., 3.14 ). Example: pi = 3.14 print ( type (pi)) # Output: <class 'float'>  ->Boolean: For true/false values ( True , False ). Example: is_active = True print(type(is_active))  # Output: <class 'bool'> 3.
