python - Python嵌套列表删除括号

我创建了一个程序，该程序从与主题相关联的文本文档中导入的列表中选择随机项目。饮食中的食物包含比萨饼，面食和汉堡。但是，当打印出结果时，所选项目将带有括号，方括号和语音标记。我将如何删除它们？

things_to_do=[
("eat", [(foods[randint(0,20)])]),
("do", [(sports[randint(0,60)])]),
("drink a",[(coffees[randint(0,20)])])]



print "Whilst in town you decided to " + str(things_to_do[randint(0,2)])]

最佳答案

这些括号，引号等只是更复杂的数据结构（例如string representation或lists）的tuples的一部分。您需要正确准备/格式化数据以获得更好的输出：

things_to_do = [
  ("eat", foods[randint(0,20)]),  # less complex than the singleton lists in your code
  ("do", sports[randint(0,60)]),
  ("drink a", coffees[randint(0,20)])
]
verb, obj = things_to_do[randint(0,2)]
print "Whilst in town you decided to {v} {o}".format(v=verb, o=obj)

String formatting in the docs。
