How to generate a random number between 0 and 1 in Python ? (original) (raw)
Last Updated : 03 Jan, 2021
The use of randomness is an important part of the configuration and evaluation of modern algorithms.
Here, we will see the various approaches for generating random numbers between 0 ans 1.
Method 1:
Here, we will use uniform() method which returns the random number between the two specified numbers (both included).
Code:
Python3 `
import random
print(random.uniform(0, 1))
`
Output:
0.0023922878433915162
Method 2:
Here, we will use random() method which returns a random floating number between 0 and 1.
Code:
Python3 `
import random
print(random.random())
`
Output:
0.7769332461684861
Method 3:
Here, we will use the numpy to generate the array of the random numbers.
Code:
Python3 `
import numpy as np
x=np.random.random(1)[0] print(x)
`
Output:
0.03394418147881839
Method 4:
Here, we will see the custom approach for generating the random numbers.
randint() is the method which return the random integer between two specified values.
Code:
Python3 `
import random
print(random.randint(0, 105)/ 105)
`
Output:
0.59882
