Python BeautifulSoup NameError: name 'src' is not?

Question

Python

Hello everyone, I am writing a parser for wildberries
Here is the whole code:

from bs4 import BeautifulSoup
import requests
from requests.api import head
import io
import random
import numpy


def get_html():
    '''Получение html кода'''
    headers = {
        "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36",
        "accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9"
    }

    url = 'https://www.wildberries.ru/catalog/muzhchinam/odezhda/vodolazki'
    html = requests.get(url,headers=headers)

    global src
    src = html.text


def get_pages():
    """получение количества страниц"""
    soup = BeautifulSoup(src , 'lxml')
    try:
        good_count = soup.find('h1').find_next('span').get_text(strip=True).replace("\xa0", '').split()[0]
        pages = int(good_count) // 100 + 1
    except:
            pages = 1
    print(f'''Количество страниц:{pages}''')

def get_price():
    '''получение цены товара'''
    soup = BeautifulSoup(src , 'lxml')
    h1 = soup.find_all(class_="lower-price")
    print(h1)

def main ():
   get_price()
    get_html()
    get_pages()

if __name__ == '__main__':
    main()

gives an error:
Traceback (most recent call last):
File "C:\Users\adaml\PycharmProjects\wildparser2\app.py", line 89, in

File "C:\Users\adaml\PycharmProjects\wildparser2\app .py", line 84, in main

soup = BeautifulSoup(src , 'lxml')
NameError: name 'src ' is not defined

Answer 1

1. the global variable itself is declared a level higher
2. but, you don’t need to use global, especially for a beginner
3. you must explicitly return the result from the function, just as explicitly (and not through global) pass this result to another function
PS the order of the function call, hints at a problem with logic.
