uniform() method in Python Random module

  • Difficulty Level : Basic
  • Last Updated : 15 Oct, 2020

uniform() is a method specified in the random library in Python 3.

Nowadays, in general, day-day tasks, there’s always the need to generate random numbers in a range. Normal programming constructs require a method more than just one word to achieve this particular task. In python, there’s an inbuilt method, “uniform()” which performs this task with ease and using just the one word. This method is defined in “random” module

Syntax : uniform(int x, int y)

Parameters :
x Specifies the lower limit of the random number required to generate.
y Specifies the upper limit of the random number required to generate.

Returns : Returns the generated floating point random number between lower limit and upper limit



 
Code #1 : Code to generate float random number.




# Python3 code to demonstrate
# the working of uniform()
  
# for using uniform()
import random
  
# initializing bounds 
a = 4
b = 9
  
# printing the random number
print("The random number generated between 4 and 9 is : ", end ="")
print(random.uniform(a, b))

Output:

The random number generated between 4 and 9 is : 7.494931618830411

Application :
There are many possible applications that can be thought of this function, some of the notable being generating random numbers in casino games, for lottery or custom games.
Below is the game that decided the winner on the basis of closeness to a certain value.

 
Code #2 : Application of uniform() – A Game




# Python3 code to demonstrate
# the application of uniform()
  
# for using uniform()
import random, math
  
# initializing player numbers
player1 = 4.50
player2 = 3.78
player3 = 6.54
  
# generating winner random number
winner = random.uniform(2, 9)
  
# finding closest 
diffa = math.fabs(winner - player1)
diffb = math.fabs(winner - player2)
diffc = math.fabs(winner - player3)
  
# printing winner
if(diffa < diffb and diffa < diffc):
    print("The winner of game is : ", end ="")
    print("Player1")
  
if(diffb < diffc and diffb < diffa):
    print("The winner of game is : ", end ="")
    print("Player2")
      
if(diffc < diffb and diffc < diffa):
    print("The winner of game is : ", end ="")
    print("Player3")

Output:

The winner of game is : Player2
