if语句与bs4输出中的String匹配

Question

Need some assistance. I have a function where I use the find_all function on my bs object to print some specific html. my goal here is to eventually match the productName and color together so I can go to the correct link but I am having some trouble picking out the correct word. Here is my code and I get no output when I run this.

def getPremeProduct() -> str:
session = requests.Session()
base = "http://www.supremenewyork.com"
r = session.get('http://www.supremenewyork.com/shop/all/accessories')
soup = BeautifulSoup(r.content, 'lxml')
keyword = input('Input your keyword: ')
color = str(input('input your color: '))
productColor = soup.findAll('p', text=re.compile(r'\bChecker\b'))
productName = soup.findAll('a', text=re.compile(r'\bTees\b'))

if "Checker" in productName:
    print(productName)

### Here are the outputs for productName
#<a class="name-link" href="/shop/accessories/s4o3fjcg0/eq35gubw7">Supreme®/Hanes® Checker Tagless Tees (2 Pack)</a>
#<a class="name-link" href="/shop/accessories/hz7wj2ui4/jx7qm1hsc">Supreme®/Hanes® Tagless Tees (3 Pack)</a>
#<a class="name-link" href="/shop/accessories/hz7wj2ui4/yks6zay73">Supreme®/Hanes® Tagless Tees (3 Pack)</a>

Anyone have any ideas why my if statement isn't printing out just the one result that has "Checker" included? Thanks

Answer 1

There are some problems with your code:

1. You should indent your code when defining a function. Ie code under def should be indented wrt. the def keyword.
2. why use input if you are not using it later?
3. pep 8 specifies a naming convention for variable names. It might be a good idea to follow that. To be more specific:

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

Variable names follow the same convention as function names.

Going back to your problem, the most straight forward way of doing what you want is:

import requests
from bs4 import BeautifulSoup
import re

def get_product():
    session = requests.Session()
    r = session.get('http://www.supremenewyork.com/shop/all/accessories')
    soup = BeautifulSoup(r.content, 'lxml')
    product_names = soup.findAll('a', text=re.compile(r'\bTees\b'))
    product_names = [link.get_text() for link in product_names]
    return product_names

products = get_product()
for item in products:
    if 'Checker' in item:
        print('yas gurl!')

Answer 2

soup.findAll finds mutiple elements. You therefore need to iterate them:

import requests
from bs4 import BeautifulSoup

def getPremeProduct() -> str:
    session = requests.Session()
    base = "http://www.supremenewyork.com"
    r = session.get('http://www.supremenewyork.com/shop/all/accessories')
    soup = BeautifulSoup(r.content, 'lxml')
    keyword = input('Input your keyword: ')
    color = str(input('input your color: '))
    productColor = soup.findAll('p', text=re.compile(r'\bChecker\b'))
    productNames = soup.findAll('a', text=re.compile(r'\bTees\b'))

for product_name in ProductNames:
    product_name = str(product_name)
    if "Checker" in product_name:
        print(product_name)
