# What is numpy.random.shuffle and seed

In this blog, we would discuss What is numpy.random.shuffle and seed.The numpy.random.shuffle function is a great way to generate random numbers in Python. The numpy.random.shuffle() method allows us to randomly arrange various integer values within a NumPy array, or we may indicate that all the values in an array will be shuffled.

The numpy.random.seed() function allows you to generate random numbers based on a seed. Basically, you give it a number and it will generate a random number based on that. If you give it the same number, it will generate the same random number. This can be really useful if you need to generate random numbers for a simulation or something like that. You can just save the seed and then use it to generate the same numbers later.

## What is numpy.random.shuffle

If you’re looking to shuffle a array or list in Python, the best way to do it is with the numpy.random.shuffle function. This function takes in an array or list and shuffles it in place, meaning that it doesn’t return anything, it just shuffles the array or list that you pass in. To use this function, you first need to **import NumPy**. One thing to keep in mind is that numpy.random.shuffle is only guaranteed to work correctly if the array has more than one element. If you try to shuffle an array with only one element, the array will remain unchanged.

This is a great function to use if you need to generate random numbers for things like games or simulations. It’s also a good option if you need to randomly shuffle a list of data. For example, you could use this function to shuffle a list of names so that you can randomly select people for a prize drawing. To use this function, you just need to pass in the array that you want to shuffle.

The function will then shuffle the array in place, meaning that the original order of the elements will be lost. Keep in mind that this function is only meant to shuffle arrays of homogeneous data. If you try to shuffle an array with different data types, you’ll likely get an error. Overall, the numpy.random.shuffle function is a great way to generate random numbers in Python. It’s simple to use and can be a great addition to your toolkit when working with data.

## Implementation of numpy.random.shuffle

For example, if we have an array of integers called arr, we can shuffle it like this:

import numpy as np arr = np.array([1, 2, 3, 4, 5]) np.random.shuffle(arr) print(arr)

As you can see, the array is now in random order.

## What is numpy.random.seed()?

If you want to be able to generate the same random numbers, again and again, there’s a simple way to do this in Python using the numpy.random.seed() function. The seed is an integer that is used to initialize the random number generator. If you don’t specify a seed, the random number generator will use the current system time to generate a seed.

Once the random number generator has been seeded, it will generate the same sequence of random numbers every time. This can be useful if you want to reproduce results from a previous simulation. To seed the random number generator, you can use the numpy.random.seed() function.

## Implementation of numpy.random.seed()

First, you need to import the numpy module.

`import numpy as np.`

Next, you can use the np.random.seed() function to set the seed for the random number generator. For example, if you want to generate the same random numbers as me, you would use the following seed: np.random.seed(42) Now, whenever you call a function from the numpy.random module, it will generate the same results.

For example, let’s say we want to generate 10 random numbers between 0 and 1:

np.random.seed(42) np.random.rand(10)

Output:

And if we generate 10 more numbers, they will be the same as well:

np.random.rand(10)

Output:
