Tell us what’s happening:

Your code so far

def pin_extractor(poem):
    secret_code = ''
    lines = poem.split('\n')
    for line_index, line in enumerate(lines):
        words = line.split()
        if len(words) > line_index:
            secret_code += str(len(words[line_index]))
        else:
            secret_code += '0'
    return secret_code

poem = """Stars and the moon
shine in the sky
white and
until the end of the night"""

The global keyword is used to reference a global variable in another function; so it can be modified. Without the global keyword all variables will be treated as local.

ok i wrote it like this global poem2

poem2 =the text

global poem3

poem3=the text

print(pin_extractor(poem))

what is the problem now

Hi @hassan12,

Please just follow the instructions. You only need to add two more poems.

Look at the poem variable in the starting code. There is no global keyword and there are no newline characters because the text is surrounded by triple quotes. Pattern your new poems like that one.

You also did not comment out the print as asked. In fact, you changed it.

Edit: About global scope. This is an excerpt from the reference provided: “Global variables are declared outside all functions and can be accessed anywhere in the program, including inside functions.” Global and Local Variables in Python - GeeksforGeeks

Happy coding!
