random.seed()

The `random.seed()` function is used to initialize the random number generator in Python. By setting a seed value, the sequence of random numbers generated will be the same every time the program is run with that same seed value.

For example, if you set the seed value to 42 using `random.seed(42)`, the first randomly generated number will always be the same (0.6394267984578837) every time the program is run with that same seed value.

This can be useful in situations where you want to reproduce a specific sequence of random numbers, such as in testing or research. However, it's important to note that using the same seed value can also lead to predictability and potential security risks in some applications.
