Study Notes
Boolean Data Types
- Boolean data types are used to represent True or False values.
- Boolean variables can store one of the two values: True or False.
- True and False are reserved words in Python and cannot be used as identifiers.
Comparison Operators
- There are six comparison operators (also known as relational operators) used to compare two values:
==(equal to)!=(not equal to)>(greater than)<(less than)>=(greater than or equal to)<=(less than or equal to)
- The result of a comparison is a Boolean value: True or False.
Conversion Between Boolean Values and Integers
int(True)returns 1.int(False)returns 0.
Conversion Between Numeric Values and Boolean Values
bool(0)returns False.bool(any other numeric value)returns True.
Generating Random Numbers
- The
randommodule provides functions for generating random numbers. - To generate a random integer between
aandb(inclusive), userandom.randint(a, b). - To generate a random float between 0 and 1, use
random.random().
