问题相关代码，请勿粘贴截图

import requests
import re

def getHtmlText(url):
    try:
        r = requests.get(url, timeout = 30)
        r.raise_for_status()
        r.encoding = r.apparent_encoding
        return r.text
    except:
        return ""
    
def parsePage(ilt,html):
    try:
        plt = re.findall(r'\"view_price"\:\"[\d\.]*\"', html)
        tlt = re.findall(r'\"raw_title"\:\".*?\"', html)
        for i in range(len(plt)):
            price = eval(plt[i].split(":")[1])
            title = eval(tlt[i].split(":")[1])
            ilt.append([price, title])
    except:
        print("666")

def printGoodsList(ilt):
    tplt = '{:4}\t{:8}\t{:16}'
    print(tplt.format("序号","价格","名称"))
    count = 0
    for j in ilt:
        count = count + 1
        print(tplt.format(count, j[0],j[1]))

def main():
    goods = '书包'
    depth = 2
    u = 'https://s.taobao.com/search?q=' + goods
    infolist = []
    for i in range(depth):
        try:
            url = u + '&s=' + str(44*i)
            html = getHtmlText(url)
            parsePage(infolist, html)
        except:
            continue
    printGoodsList(infolist)

main()
