I want to assign random label (0 or 1) to a data set. How can I create a list containing only 0 and 1?

E.g.

y = [1,0,1,1,0,0,1,0]

E.g.

y = [1,0,1,1,0,0,1,0]

You can use functions of the Python module "random" to create a list of 0 and 1 only.

- Using
**randint(a,b)**: You can provide a=0 and b=1 in this function to get only 0 or 1 in the list. - Using
**random()**: It generates a random float value between 0 and 1. You can apply round() to the float value to get 0 or 1. - Using
**uniform(a,b)**: It generates a random float value between a and b. You can provide a=0 and b=1 in this function and apply round() to the float value to get 0 or 1.

Here are examples using these functions:

>>> import random

>>> sample_size=10>>> labels = [random.randint(0,1) for _ in range(sample_size)]

>>> labels

[0, 0, 1, 1, 0, 1, 1, 1, 1, 1]>>> labels =[round(random.random()) for _ in range(sample_size)]

>>> labels

[0, 0, 0, 0, 0, 1, 1, 1, 1, 0]>>> labels =[round(random.uniform(0,1)) for _ in range(sample_size)]

>>> labels

[0, 0, 0, 1, 0, 0, 1, 1, 1, 0]
