functional programming - Passing arguments through several functions in Python -

this question related best practice.

let's have following code:

def clean_text(text, idx):    title = sqlalchemy.query("select title page_titles id = %s" % idx)    return {title: text}  def scrape_webpage(idx):    """ stuff here"""    response = requests.get(link)    return clean_text(response.text, idx)  def main():    idx in range(10):       scrape_webpage(idx)  if __name__ == '__main__':    main() 

the main problem have code there statefulness required (namely idx) being passed through scrape_webpage. can imagine if have many functions before clean_text() invoked, idx has passed through of them without being used in of them.

is there better way clean_text can know state of loop without having passed argument (and incidentally, through of functions use it)? perhaps generators or callbacks? appreciate example.
