本文執行個體為大家分享了python爬取淘寶商品的具體代碼，供大家參考，具體内容如下

import requests as req

import re

def getHTMLText(url):

try:

r = req.get(url,timeout=30)

r.raise_for_status()

r.encoding = r.apparent_encoding

return r.text

except:

return ""

def parasePage(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("")

def printGoodsList(ilt):

tplt = "{:4}\t{:8}\t{:16}"

print(tplt.format("序列号","價格","商品名稱"))

count = 0

for j in ilt:

count = count + 1

print(tplt.format(count,j[0],j[1]))

def main():

goods = "python爬蟲"

depth = 3

start_url = 'https://s.taobao.com/search?q=' + goods
