An overview for working with randomness in Python, using only functionality built into the standard library and CPython itself. Generating Random Floats Between 0.0 and 1.0 With the random.randrange() function you can exclude the right-hand side of the interval, meaning the generated number always lies within [x, y) and it will always be smaller than the right endpoint:

Every time the device is reset it displays a number between 1 and 6. You’re starting to get familiar with nesting, so it’s important to note that random.randint returns a whole number between the two arguments, inclusive (a whole number is also called an integer – hence the name of the method).
