Python-将列表中的项目连接到字符串

Question

有没有更简单的方法将列表中的字符串项连接为单个字符串？我可以使用该str.join()功能吗？

例如，这是输入['this','is','a','sentence']，这是所需的输出this-is-a-sentence

sentence = ['this','is','a','sentence']
sent_str = ""
for i in sentence:
    sent_str += str(i) + "-"
sent_str = sent_str[:-1]
print sent_str

Answer 1

用途join：

>>> sentence = ['this','is','a','sentence']
>>> '-'.join(sentence)
'this-is-a-sentence'
