如何从熊猫的字符串列中删除https链接

Question

我有以下数据框：

import pandas as pd
df = pd.DataFrame({'col':['text https://random.website1.com text', 'text https://random.website2.com']})

我想删除此列中的所有链接。

有什么想法吗？

Answer 1

将列表理解与拆分和测试URL结合使用，最后按空格连接值：

from urllib.parse import urlparse
#https://stackoverflow.com/a/52455972
def is_url(url):
  try:
    result = urlparse(url)
    return all([result.scheme, result.netloc])
  except ValueError:
    return False

df['new'] = [' '.join(y for y in x.split() if not is_url(y)) for x in df['col']]
print (df)
                                     col        new
0  text https://random.website1.com text  text text
1       text https://random.website2.com       text

Answer 2

使用正则表达式。

例如：

import pandas as pd
df = pd.DataFrame({'col':['text https://random.website1.com text', 'text https://random.website2.com']})
#Ref https://stackoverflow.com/questions/10475027/extracting-url-link-using-regular-expression-re-string-matching-python
df["col_new"] = df["col"].str.replace(r'https?://[^\s<>"]+|www\.[^\s<>"]+', "")
print(df)

                                     col     col_new
0  text https://random.website1.com text  text  text
1       text https://random.website2.com       text
