url = {"http://finance.com/quote.ashx?t=" + col[i].text}
print(url)

Answer 1

尝试创建一个新列：

data['urls'] = data['Symbol'].apply(lambda x: "http://finance.com/quote.ashx?t=" + x)

或者只获取包含所有 url 的列表：

urls = ["http://finance.com/quote.ashx?t=" + x  for x in data['Symbol'].tolist()]

完整代码：

import pandas as pd
data = pd.read_csv("fornews_list.csv")
urls = ["http://finance.com/quote.ashx?t=" + x  for x in data['Symbol'].tolist()]
print(urls)

连接 url + dtype: string

Concatenate url + dtype: string

python
