NumPy provides the random module. This module contains the functions which are used for generating random numbers. The most frequently used functions of this module are listed below:
| Functions | Description |
|---|
| rand() |
Returns random values drawn from uniform distribution in a given shape. |
| randn() |
Returns random values drawn from standard normal distribution in a given shape. |
| randint() |
Returns random integers drawn from specified range in a given shape. |
| random_sample() |
Returns random floats in the half-open interval [0.0, 1.0) in a given shape. |
| random() |
Returns random floats in the half-open interval [0.0, 1.0) in a given shape. |
| ranf() |
Returns random floats in the half-open interval [0.0, 1.0) in a given shape. |
| sample() |
Returns random floats in the half-open interval [0.0, 1.0) in a given shape. |
| choice() |
Generates a random sample from a given 1-D array. |
| bytes() |
Return random bytes. |
| Functions | Description |
