Generate random numbers between specific range in Python

This post will discuss how to generate n random numbers between the specified range in Python.

1. Using `random.randint()` function

The random.randint(x, y) function generates the random integer n such that x <= n <= y. You can use it as following to generate random numbers between a certain range:

import random

if __name__ == '__main__':

start = 2 # inclusive

end = 5 # inclusive

n = 10 # size

x = [random.randint(start, end) for _ in range(n)]

print(x)

2. Using `random.randrange()` function

If you need to generate a random number exclusive of the end argument (i.e., x <= n < y), consider using the random.randrange(x, y) function. In other words, random.randrange(x, y+1) is same as the random.randint(x, y).

import random

if __name__ == '__main__':

start = 2 # inclusive

end = 5 # exclusive

n = 10 # size

x = [random.randrange(start, end) for _ in range(n)]

print(x)

3. Using `random.choices()` function

Another plausible way to generate random numbers from a continuous sequence is using the random.choice() function.

import random

if __name__ == '__main__':

start = 2 # inclusive

end = 5 # exclusive

n = 10 # size

x = random.choices(range(start, end), k=n)

print(x)

4. Using Numpy

If you prefer Numpy, you can try numpy.random.randint() or numpy.random.uniform() function.

⮚ numpy.random.randint

import numpy as np

if __name__ == '__main__':

start = 2 # inclusive

end = 5 # exclusive

n = 10 # size

x = np.random.randint(low=start, high=end, size=(n))

print(x)

⮚ numpy.random.uniform

import numpy as np

if __name__ == '__main__':

start = 2 # inclusive

end = 5 # exclusive

n = 10

x = np.random.uniform(low=start, high=end, size=(n)).astype(int)

print(x)

That’s all about generating random numbers between specified ranges in Python.
