Using a for loop with .join

I am making a program to make 12 word long phrases using the bip39 wordlist.

However with the code I wrote I am getting an error I do not know how to fix.

Code:

import requests
import random
r = requests.get("https://raw.githubusercontent.com/bitcoin/bips/master/bip-0039/english.txt")

def make_seed():
    return "".join([random.choice(r.text.split("\n")) + " "] for i in range(12))

print(make_seed())

Output: TypeError: sequence item 0: expected str instance, list found

Expected output: 12 letter phrase from the wordlist.

I tried turing the random.choice(r.text.split("\n")) into a str but that doesn't seem to work.

The join method requires as its argument an iterable of str objects. Your iterable is of list objects. Try removing the brackets from that line. I.e.,

return "".join(random.choice(r.text.split("\n"))+" " for i in range(12))
