Unable to fetch product url using BeautifulSoup with Python3.6

[Larz60+]

please post enough code to run without work, it forces us to improvise, perhaps causing differnet results:

My attempt:

from bs4 import BeautifulSoup
import requests


def get_soup(url):
    soup = None
    try:
        response = requests.get(url, headers=headers, timeout=timeout)
        if response.status_code == 200:
            html = response.content
            soup = BeautifulSoup(html, "html.parser")
    except Exception as exc:
        print("error::", str(exc))
    finally:
        return soup
 
def get_category_urls(url):
    soup = get_soup(url)
    cat_urls = []
    try:
        categories = soup.find('div', attrs={'id': 'menu_oc'})
        if categories is not None:
            for c in categories.findAll('a'):
                if c['href'] is not None:
                    cat_urls.append(c['href'])
    except Exception as exc:
        print("error..", str(exc))
    finally:
        print("category urls::", cat_urls)
        return cat_urls

def main():
    url = 'http://www.infantree.net/shop/'
    soup = get_soup(url)

if __name__ == '__main__':
    main()

Error:
error:: name 'headers' is not defined
