### Tell us what’s happening:

def pin\_extractor(poems):  
for poem in poems:  
secret\_code = ‘’  
lines = poem.split(‘\n’)

```auto
    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'

```

Please **Tell us what’s happening** in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!
