python：檢查子字符串是否在字符串元組中

Question

檢查字符串元組中是否存在多個子字符串的最優雅方法是哪種？

tuple = ('first-second', 'second-third', 'third-first') 
substr1 = 'first' 
substr2 = 'second' 
substr3 = 'third'
#if substr1 in tuple and substr2 in tuple and substr3 in tuple:
#    should return True

Answer 1

any(substr in str_ for str_ in tuple_)

您可以從此開始，也可以查看all() 。

Answer 2

您需要遍歷每個子字符串的元組，因此使用any和all ：

all(any(substr in s for s in data) for substr in ['first', 'second', 'third'])
