# help random item challenge

item.py
```# EXAMPLE
# random_item("Treehouse")
# The randomly selected number is 4.
# The return value would be "h"
import random
def random_item(arg):
arg = random.randint(len(arg)) -1
return arg
```

Hiya! You are close but there are a couple issues with code, and this might help ya a bit:

```import random

def random_item(words):
num = random.randint(0, len(words)-1)
return words[num]
```

thanks ! it worked! but I don't understand what the ( ) after the random.randint, I do understand len(words)-1) but what is the 0 does? and why the -1 isn't outside the ( )?

thanks a ton!

Idan , if you look at docs for "random.randint()" module, "randint()" takes two arguments a and b. Where a is the starting point and b is the end. Hence, randint will randomly select an integer between "a" and "b". In case , if ya wont provide any arguments, "randint" will randomly select an integer between 0 and 1 for ya. So yeah to override the arguments a and b in randint, as per instructions given in the challenge, the range was given to randint was "0" and "len(words)-1". I hope it helped! (:
