複数のリストから特定の行を抽出するインデックスエラー

Question

import urllib.request 
import bs4 as bs 
import requests 
import re 

url = " https://www.weather-forecast.com/locations/Kansas-City- 
1/forecasts/latest" 
request = requests.get(url) 
response = request.text 

soup = bs.BeautifulSoup(response,'lxml') 

for para in soup.find_all('p'): 

    a = para.text.split('/n') 

    print(a[1]) 

私は例えば印刷しています。リストから94.5Wまでの行だけですが、それは私に範囲外のエラーのインデックスを与えます。 これは私だけ行う場合、私が得る出力されます：

print(a) 
[''] 
['Kansas City is 232\u2009m above sea level and located at 39.05° N 94.50° 
W. Kansas City has a population of 475378. Local time in Kansas City is 
CST.'] 
['Kansas City 1 – 3 Day Weather Forecast Summary: Mostly dry. Freeze-thaw 
conditions (max 10°C on Wed afternoon, min -2°C on Thu night). Wind will be 
generally light.']

しかし、私は唯一のため、私はあなたがループ内a変数を宣言し、それを印刷している

Answer 1

をしたい特定の行を印刷したいですリストには1つの要素があり、毎回上書きされます。 a宣言とprint()をforループの外に移動すると、そのトリックを行う必要があります

import bs4 as bs 
import requests 
import re 

url = " https://www.weather-forecast.com/locations/Kansas-City-1/forecasts/latest" 
request = requests.get(url) 
response = request.text 

soup = bs.BeautifulSoup(response,'lxml') 

a=[] 
for para in soup.find_all('p'): 

    a.append(para.text.split('/n')) 

print(a[1])
