python - 如何将列表中的值输入到字符串中？

Question

我正在尝试将以下列表值输入到下面的 url 字符串中。 当我执行以下操作时:

tickers = ['AAPL','YHOO','TSLA','NVDA']
url = 'http://www.zacks.com/stock/quote/{}'.format(tickers)`

Python 返回

http://www.zacks.com/stock/quote/['AAPL', 'YHOO', 'TSLA', 'NVDA']`

我希望它做的是遍历列表并返回以下内容:

http://www.zacks.com/stock/quote/AAPL
http://www.zacks.com/stock/quote/YHOO
http://www.zacks.com/stock/quote/TSLA
http://www.zacks.com/stock/quote/NVDA

谢谢。

Answer 1

map 的绝妙技巧:

url = 'http://www.zacks.com/stock/quote/{}'
tickers = ['AAPL','YHOO','TSLA','NVDA']

list(map(url.format, tickers))

['http://www.zacks.com/stock/quote/AAPL',
 'http://www.zacks.com/stock/quote/YHOO',
 'http://www.zacks.com/stock/quote/TSLA',
 'http://www.zacks.com/stock/quote/NVDA']
