How to use the random.randrange() method in Python
Onyejiaku Theophilus ChidaluOverview
The random.randrange() method returns a randomly selected element from a given range. This method is similar to random.choice(), except random.randrange() does not build a range object.
Syntax
random.randrange(start,stop,step)
Parameters
start(optional): An integer that specifies the position where the elements to be returned should start from.stop(optional): An integer that specifies the position where the elements to be returned should end.step(optional): An integer that specifies the increment in step size.
Example code
Let’s use the random.randrange() method to return elements for a given range.
import random # using the stop parameter print(random.randrange(2)) # using both the start and stop parameters print(random.randrange(2,15)) # using the start, stop and step parameters print(random.randrange(2,15,3))
Code explanation
- Line 1: We import the random module.
- Line 4: We use the
random.randrange()method to return an integer, starting from 0 and ending at 2. - Line 6: We use the
random.randrange()method to return an integer, starting from 2 and ending at 15. - Line 8: we use the
random.randrange()method to return an integer, starting from 2 and ending at 15, and with a step size of 3.
