Challenge Task

Can anyone please tell me how I can return a character from "Treehouse" in which the index of the character is decided from:

random.randint from 0 to (1 - the length of treehouse)?

item.py 
# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random

def random_item(item):
    item = "Treehouse"
    rando = random.randint(0, len(item) - 1)

    while True:
        return item[rando]

Your code is very close to correct*. remove the line assigning item = "Treehouse". This overwrites the argument supplied by the challenge checker causing it to not get the expected response. The string "Treehouse" is only an example of the type of input the function can expect and not literally the exact input.

*I should have said "close to passing" instead of 'close to correct". See Tushar Mehta's response.

Any particular reason for using while True: ? You should return random character straight away.
