# 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
```
