Use the random.choices() function to select multiple random items from a sequence with repetition. # Output random sample with replacement to including repetitions Sampled_list2 = random.sample(exampleList, 4) Let’s see the example which demonstrates the same. It chooses the repeated items from the specified list if the unique members are less than a sampling size. Important Note: If your list contains repeated or duplicate elements, then sample() can pick repeated items because each occurrence is a possible selection in the sample.
It raises a TypeError if you miss any of the required arguments.k must be less than the size of the specified list. k: It is the number of random items you want to select from the sequence.population: It can be any sequence such as a list, set, and string from which you want to select a k length number.The sample() function takes two arguments, and both are required. It returns a new list containing the randomly selected items. random.sample() function Error and exception.Get a sample array from a multidimensional array.
Random seed to get the same sample list every time.Generate the sampled list of random integers.random sample with replacement to including repetitions.Points to remember about random.sample().random sample() example to select multiple items from a list without repetition.Returns two key-value pairs from Python dictionary. Return the sampled list of unique random integers. Generate n samples from a sequence with the possibility of repetition. Here, A seq can be a list, set, string, tuple. Generate n unique samples (multiple items) from a sequence without repetition. You’ll learn the following ways to generate random samples in Python Operation Note: Use the random.choice() function if you want to choose only a single item from the list. In simple terms, for example, you have a list of 100 names, and you want to choose ten names randomly from it without repeating names, then you must use random.sample(). We call it random sampling without replacement. It returns a list of unique items chosen randomly from the list, sequence, or set. Python’s random module provides a sample() function for random sampling, randomly picking more than one element from the list without repeating elements.

We will also see how to generate a random sample array from a sizeable multidimensional array in Python. In this lesson, you will learn how to use the random.sample() function to choose sample/multiple items from a Python list, set, and dictionary.
