（（Python）Beautifull汤和编码（utf-8，cp1252，ascii ...）

Posted 2021-05-07

请帮助，我现在很放松。自从我开始学习Python以来，我遇到了这个问题。总是遇到相同的问题，任何人都无法在线给出任何有效答案

我的代码：

from bs4 import BeautifulSoup
import requests

page = requests.get(
    'https://forecast.weather.gov/MapClick.php?lat=34.05349000000007&lon=-118.24531999999999#.XswiwMCxWUk')
soup = BeautifulSoup(page.content, 'html.parser')
week = soup.find(id='seven-day-forecast-body')
items = week.find_all(class_='forecast-tombstone')

print(items[0].find(class_='period-name').get_text())
print(items[0].find(class_='short-desc').get_text())
print(items[0].find(class_='temp temp-high').get_text())

period_names = [item.find(class_='period-name').get_text() for item in items]
short_descp = [item.find(class_='short-desc').get_text() for item in items]
temp = [item.find(class_='temp temp-high').get_text() for item in items]
print(period_names)
print(short_descp)
print(temp)

输出：

[Running] python -u "c:UsersdukasuDocumentsPython	est.py"
ThisAfternoon
Partly Sunny
High: 76 �F
Traceback (most recent call last):
  File "c:UsersdukasuDocumentsPython	est.py", line 20, in <module>
    temp = [item.find(class_='temp temp-high').get_text() for item in items]
  File "c:UsersdukasuDocumentsPython	est.py", line 20, in <listcomp>
    temp = [item.find(class_='temp temp-high').get_text() for item in items]
AttributeError: 'NoneType' object has no attribute 'get_text'

[Done] exited with code=1 in 0.69 seconds

问题是由于utf-8编码（我的电脑在cp1252上），但是如何最终解决它（我认为问题是cos无法使用度数符号进行操作）。 Python 2中有一个简单的代码，但是如何在Python 3.xx中解决它。如何在代码开始时设置编码，而忽略此问题。anp请原谅我的英语，这不是我的母语。

答案

错误来自类名，仅使用class_='temp不使用class_='temp temp-high

示例

temp = [item.find(class_='temp').get_text() for item in items]
