A **random number** is a number that cannot be predicted logically. A random number does not necessarily mean a different number each time.

Note: Any random number generated through any generation algorithm is called a

pseudo-random number. This is because the algorithm can repeat the sequence, and the numbers are not entirely random.

Bearing that in mind, we can say that a program written to generate a random number is never truly random.

In this shot, we’ll take a look at how to generate pseudo-random numbers.

To generate a pseudo-random number in `NumPy`

, we will need the `random`

module offered by `NumPy`

.

In the code below, we will generate a pseudo-random integer between `0`

and `10`

:

# importing the random module from numpy from numpy import random # using the randit() method to generate random integers from 0 to 10 x = random.randint(10) # printing the random numbers print(x)

Printing a pseudo-random number

- Line 2: We import the
`random`

module from`NumPy`

. - Line 5: We generate a random integer number between
`0`

and`10`

using the`randit()`

function. - Line 8: We print the pseudo-random number.

Note: The

function is used to generate pseudo-random integers.`randint()`

Let’s take a look at another example.

In the code below, we want to use the `rand()`

function to generate a pseudo-random float number between `0`

and `1`

.

# importing the random module from numpy from numpy import random # using the rand() method to generate random integers from 0 to 10 x = random.rand(1) # printing the random float numbers print(x)

Printing pseudo-random float numbers

- Line 2: We import the
`random`

module from`NumPy`

. - Line 5: We generate a random float number between
`0`

and`1`

using the`rand()`

function. - Line 8: We print the pseudo-random float number.

Note: The

`rand()`

function is used to generate pseudo-random float numbers.
