# Generate Random Numbers in a Python List

Here are 2 ways to generate random numbers in a Python list:

(1) Generate random numbers that cannot be repeated:

`import randommy_list = random.sample(range(lowest number, highest number), number of items in the list)print(my_list)`

For example, let’s generate 15 random numbers, where the lowest number is 1 (inclusive), while the highest number is 30 (exclusive):

`import randommy_list = random.sample(range(1, 30), 15)print(my_list)`

As you can see, the number of items (i.e., random numbers in the list) is 15, which cannot be repeated:

``[6, 16, 3, 5, 22, 24, 1, 7, 11, 4, 29, 13, 17, 28, 25]``

(1) Generate random numbers that can be repeated:

`import numpy as npdata = np.random.randint(1, 30, size=15)my_list = data.tolist()print(my_list)`

As can be observed, a random number may appear more than once in the list (e.g., 18 and 10 below):

``[7, 2, 23, 18, 12, 6, 18, 20, 24, 10, 4, 9, 10, 17, 15]``

Note that:

• Numpy was used to generate 15 random numbers from 1 (inclusive) to 30 (exclusive)
• tolist() was used to convert the NumPy array to a list
