Using a returned for loop variable in main function

Question

I want to use the variable of a for loop in my main function.

This will throw an error saying x is undefined:

text = 'rough example'
def splitter(text):
    for x in sent_tokenize(text):
        print(x)
        return x

def main():
    x = splitter(text)

main()

Answer 1

try adding in the beginning of your code:

import nltk
nltk.download('punkt')

It worked for me... (printing "rough example", no error thrown)
