问题描述
这总是让我感到困惑.看来这样会更好:
This has always confused me. It seems like this would be nicer:
my_list = ["Hello", "world"] print my_list.join("-") # Produce: "Hello-world"胜过这个:
my_list = ["Hello", "world"] print "-".join(my_list) # Produce: "Hello-world"是否有特定原因?
推荐答案这是因为任何可迭代项都可以连接,不仅是列表,而且结果和"joiner"始终是字符串.
It's because any iterable can be joined, not just lists, but the result and the "joiner" are always strings.
E.G:
import urllib2 print '\n############\n'.join( urllib2.urlopen('data.stackexchange/users/7095'))更多推荐
