I wanted to know how I could create a string of random numbers by entering the length that the string should have. For example, that the program generates a list between 1 and 9 and has a length of 3 characters. Thanks

python python-3.x

Correct syntax of document.getElementById [duplicate] Is there a way to create a list for each item in another list?

If I understood you correctly, it would be something like this:

import random

result = []

for x in range(0,3):
    result.append(random.randint(0,9))

print result

The result is the following (it could have been other numbers):

[0, 5, 8]

Each time you run the script it will give you a different result. Hope it has fit. Greetings !!

A very simple way, is to use random.choice() that gets a random value from a certain list:

import random

valores = [2,4]
size = 3

random.seed(5) # Esto solo para hacer reproducible el ejemplo

print("".join([str(random.choice(valores)) for i in range(size)]))
442

Details:

random.seed(5) you can delete it, it's just to set the initial seed, and make the example reproducible, so if you run the code the result will be the same as I get.
We define valores with the list of values from which we want to obtain each part of the chain and the size of the same in size
We use an understanding of lists to generate first a list of chains of size size : [str(random.choice(valores)) for _ in range(size)]
We use the join() method that each string has, to concatenate a list
