python：檢查子字符串是否在字符串元組中

Question

哪一種檢查字符串元組中是否存在多個子字符串的最優雅方法？

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

您需要遍歷元組的每個子，因此使用any和all：

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

Answer 2

any(substr in str_ for str_ in tuple_) 

您可以用開始和all()看爲好。
