Python: Random Numbers
Python's default random library can be very handy when you need to create random numbers.
randint for an integer between lower and upper limits:
import random x=random.randint(55, 555) print(x)
Output:
477
randrange(start, stop, steps), will also give a value in the range but you can also specify a step.
import random x=random.randrange(0, 50, 4) print(x)
Output:
24
random() will return a float value between 0 and 1. This can also be used as a random percentage.
You can explore other methods of the random library by using dir(random) and help(random)
import random x=random.random() print(x)
Output:
0.30172304827477603
