This is my way: Years later, some timeits for choosing 40000 out of 10000^2 If that's not an issue, a faster solution would be to generate a sample s = np.random.randint (len (X)**2, size=n) and use s // len (X) and s % len (X) to provide the indices (since these simple operations are much faster than running the Mersenne Twister for the additional rounds, the speed-up being roughly a doubling).

The random module provides various methods to select elements randomly from a list, tuple, set, string or a dictionary without any repetition. The default value is np.int. It is used for random selection from a list of items without any replacement.Example 1: We can also use the sample() method on a sequence of numbers, however, the number of selections should be greater than the size of the sequence.Example 2: Using choices() method in the random library, The choices() method requires two arguments the list and k(number of selections) returns multiple random elements from the list with replacement. @ssp Then just get enough random numbers and reshape Another property of the resulting random sequence is that. Install numpy using a pip install numpy. This package was developed independently of NumPy and was integrated in version Note that the reason for the iterables to be mutable is that the shuffling operation involves item re-assignment, which is not supported by immutable objects. interval. @SvenMarnach - For most purposes, though, it's random enough.

We provide programming data of 20 most popular languages, hope to help you! You can use it when you want sample some elements from a list, and meanwhile you want the elements no repeat, then you can set the " replace=False ". The order of the selected integers is undefined. The code below loads NumPy and samples without replacement 12 times from a NumPy array containing unique numbers from 0 to 11 import numpy as np np.random.seed(3) # a parameter: generate a list of unique random numbers (from 0 to 11) # size parameter: how many samples we want (12) # replace = False: sample without replacement np.random.choice(a . Pythons built-in module in random module is used to work with random data. The endpoint keyword can be used to specify open or closed intervals. This is not possible, since the state of the random number generator needs to fit in the finite memory of a computer. Most random data generated with Python is not fully random in the scientific sense of the word. high is None (the default), then results are from [0, low). If an int, the random sample is generated as if a were np.arange (a) size : int or tuple of ints, optional.
