## Overview
The **``random.seed()`` method** is used to initialize the pseudo-random number generator. The random module uses the #key# seed value: provided as a parameter to the ``random.seed()`` method #key# as a base to which it will generate a random number in python. When random numbers are used for testing, this method comes in handy as it makes the optimization of codes very easy.

## Syntax 
```
random.seed(a, version)
```
## Parameter values
| Parameter| Description|
|:-|:---|
|`a`|This is optional. It is the seed value required to generate a random number. This value should always be an integer. The default value is none, and in this case, the generator uses the current system time.|
|`version`|This is an integer value. It is required to specify how to change the parameter (``a``) into an integer. The default value is 2.|
## Example 1: How to use the random.seed() method
Now, let us generate a random number setting the seed value as 4.


import random
random.seed(4)
print(random.random())

## Explanation
* Line 1: we imported the random module.
* Line 2: we used the ``random.seed()`` method by setting the seed value to 4.
* Line 3: we printed the output.

## Example 2: Using both the seed value and the version parameter
Now, let us generate a random number by passing a seed value (5) and a version (3).


import random
random.seed(5.3)
print(random.random())

## Example 3: Using the same seed value twice 
Now, let us see what happens when we use the same seed value twice.


import random

random.seed(5)
print(random.random())

random.seed(5)
print(random.random())

As can be seen from the program above, using the same seed value twice will return the same random number twice.

Parameter	Description
`a`	This is optional. It is the seed value required to generate a random number. This value should always be an integer. The default value is none, and in this case, the generator uses the current system time.
`version`	This is an integer value. It is required to specify how to change the parameter (`a`) into an integer. The default value is 2.
