假设我们有一个列表或元组的引用序列:
reference = ['a', 'b', 'c', 'd']
我想检查参考序列中是否存在某些序列:
target1 = ['a', 'b', 'c'] # true
target2 = ['a', 'c', 'b'] # false
target3 = ['a', 'c', 'd'] # false
target4 = ['c', 'd', 'e'] # false
target5 = ['c', 'd'] # true
是否有内置函数来检查这种序列成员资格? 谢谢!

我找到了相关模块FACT: [a-zA-Z](([a-zA-Z0-9] | '.' | '_')*?[a-zA-Z0-9])?;

首先,您可以将列表或元组转换为字符串,并查找引用中是否存在子字符串。一个简单的代码片段来解释我的想法:
reference = ['a', 'b', 'c', 'd']
target1 = ['a', 'b', 'c'] # true
list2str = lambda ref: "".join(ref)
base = list2str(reference)
t1 = list2str(target1)
if t1 in base:
print 'found'
else:
print 'unfound'
