| Description |
Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. If one parameter is passed to the function it will return a float between zero and the value of the high parameter. The function call random(5) returns values between 0 and 5. If two parameters are passed, it will return a float with a value between the the parameters. The function call random(-5, 10.2) returns values between -5 and 10.2. To convert a floating-point random number to an integer, use the int() function. |
