random()#

Generates random numbers.

Examples#

example picture for random()

def setup():
    py5.random_seed(42)
    for i in range(100):
        s = py5.random()
        py5.stroke(255*s)
        r = py5.random(80)
        py5.line(20, i, 20+r, i)

def setup():
    for i in range(100):
        r = py5.random(-50, 50)
        py5.println(r)

Description#

Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. This function’s randomness can be influenced by random_seed().

If no parameters are passed to the function, it will return a float between zero and one.

If only one parameter is passed to the function, it will return a float between zero and the value of the high parameter. For example, random(5) returns values between 0 and 5 (starting at zero, and up to, but not including, 5).

If two parameters are specified, the function will return a float with a value between the two values. For example, random(-5, 10.2) returns values starting at -5 and up to (but not including) 10.2. To convert a floating-point random number to an integer, use the int() function, or alternatively, consider using random_int().

This function makes calls to numpy to generate the random values.

Signatures#

random() -> float

random(
    high: float,  # upper limit
    /,
) -> float

random(
    low: float,  # lower limit
    high: float,  # upper limit
    /,
) -> float
