Generates random integers. Each time the
random_int() function is called, it returns an unexpected integer 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 either 0 or 1. Recall that in a Python boolean expression, 0 evaluates to
False and 1 evaluates to
True. This is equivalent to a coin toss.
If only one parameter is passed to the function, it will return an integer between zero and the value of the
high parameter, inclusive. For example,
random(5) returns one of 0, 1, 2, 3, 4, or 5.
If two parameters are specified, the function will return an integer with a value between the two values, inclusive. For example,
random(2, 5) returns one of 2, 3, 4, or 5.
If you want to pick a random object from a list, recall that Python uses zero-indexing, so the first index value is 0 and the final index value is one less than the list length. Therefore, to pick a random index to use in the list
words, your code should be
random_int(len(words)-1). Omitting the
-1 will (occasionally) result in an index out of range error. Alternatively, you can also use random_choice() to pick a random object from a list.
This function makes calls to numpy to generate the random integers.
random_int() -> int random_int(high: int) -> int random_int(low: int, high: int) -> int
high: int - upper limit
low: int - lower limit
