import re

data = {'text': ['Visit our website at www.example.com for more information.',

                 'Click here: http://www.example.com/contact']}
df = pd.DataFrame(data)

def remove_urls(text):
    # 定义URL的正则表达式模式
    url_pattern = re.compile(r'http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+')
    # 使用正则表达式模式查找并替换URL为空字符串
    return re.sub(url_pattern, '', text)

# 应用函数到数据帧的'text'列
df['text'] = df['text'].apply(remove_urls)

print(df)
