How to get a normal distribution within a range in numpy?

To generate a normal distribution within a specific range using NumPy, you can use the following steps:

  1. Import the necessary libraries.
  2. Define the mean and standard deviation of the desired normal distribution.
  3. Use NumPy's random.normal() function to generate random numbers from a normal distribution.
  4. Clip the generated numbers to the desired range.

Here's an example code snippet that demonstrates how to achieve this:

import numpy as np # Define the parameters of the normal distribution mean = 5.0 std_dev = 1.0 # Define the desired range min_range = 3.0 max_range = 7.0 # Generate random numbers from the normal distribution random_numbers = np.random.normal(mean, std_dev, 1000) # Generating 1000 random numbers # Clip the numbers to the desired range clipped_numbers = np.clip(random_numbers, min_range, max_range) # Print the first 10 clipped numbers print(clipped_numbers[:10])

In this example, np.random.normal() generates random numbers from a normal distribution with the specified mean and standard deviation. The np.clip() function is then used to clip these numbers to the desired range.

Adjust the mean, std_dev, min_range, and max_range values according to your requirements. The example generates 1000 random numbers, but you can change this number as needed.
