在Python中進行網(wǎng)絡爬蟲數(shù)據(jù)清洗的步驟如下:
pip install requests
pip install beautifulsoup4
pip install pandas
import requests
url = 'https://example.com'
response = requests.get(url)
html_content = response.text
from bs4 import BeautifulSoup
soup = BeautifulSoup(html_content, 'html.parser')
data = soup.find_all('div', class_='item') # 根據(jù)實際情況修改選擇器
import pandas as pd
# 將提取到的數(shù)據(jù)轉(zhuǎn)換為DataFrame
df = pd.DataFrame(data)
# 去除空值
df.dropna(inplace=True)
# 去除重復值
df.drop_duplicates(inplace=True)
# 轉(zhuǎn)換數(shù)據(jù)類型
df['price'] = df['price'].str.replace('¥', '').astype(float)
df.to_csv('cleaned_data.csv', index=False)
以上就是使用Python進行網(wǎng)絡爬蟲數(shù)據(jù)清洗的基本步驟。根據(jù)實際情況,你可能需要根據(jù)目標網(wǎng)站的結(jié)構(gòu)和需求對代碼進行調(diào)整。
