Bool
Definition
A bool is a data type in Python that represents one of two values: True or False. It is commonly used for making decisions and controlling the flow of a program.
5 Must Know Facts For Your Next Test
- The bool type in Python can take only two values: True and False.
- Bool values are often the result of comparison operators like ==, !=, >, <, >=, and <=.
- Logical operators such as 'and', 'or', and 'not' are used to combine or invert boolean values.
- In conditional statements like if-else, bool values determine which block of code will execute.
- Python treats certain values as equivalent to False (e.g., 0, '', [], {}, None) and others as True.
