Hey @coral quail!

It looks like you're trying to paste code into this channel.

Discord has support for Markdown, which allows you to post code with full syntax highlighting. Please use these whenever you paste code, as this helps improve the legibility and makes it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

list index out of range error is coming

[deft monolith]

The issue is that your list has 13 entires and you're taking value upto 13 in random.randint()

List indexing starts from 0

So it should be random.randint(0,12)

[coral quail]

13 is not excluded ?

[deft monolith]

No, random.randint() dosen't exclude the last value
the range(0, 13) does

Silly confusion I used to struggle with when I started

[coral quail]

ouuuuu

hnnn

fkkk

okok

thanks a lot !

[deft monolith]

nw

print(len(deck))

:white_check_mark: Your 3.12 eval job has completed with return code 0.

13

[coral quail]

yeshh

[uneven tinsel]

well its a list. It counts from 0, so you have to -1

[coral quail]

I got confused between range and randint

range does not use the last no.

T-T

[uneven tinsel]

Or you could just use choice instead

[deft monolith]

yes, using choice is way better

[uneven tinsel]

!d random.choice

[restive blaze]

random.choice

random.choice(seq)```
Return a random element from the non-empty sequence *seq*. If *seq* is empty, raises [`IndexError`](https://docs.python.org/3/library/exceptions.html#IndexError).

[uneven tinsel]

!e

import random
deck = [11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 10, 10, 10]
print(random.choice(deck))
print(random.choice(deck))
print(random.choice(deck))
print(random.choice(deck))
print(random.choice(deck))

001 | 3
002 | 4
003 | 3
004 | 5
005 | 11

[deft monolith]

list = ["rock", "paper", "scissor"]
print(random.choice(list))

like that

[coral quail]

okokkk

this is way better

thanks a lot guys !
