将列表吐入字符串

Question

我有一个字符串列表:

['TTGGGAGAA', 'TTGGGAGCA', 'TTGGGAGTA']

我想测试此列表中是否存在字符串:例如,测试我的列表中是否存在'GTA'(=子序列)

我试过了:

OK = subsequence in list 
if OK == True: 
    print (true)
else: pass

但它不起作用.有人能帮助我吗？

Answer 1

这是不正确的,因为它将比较列表的整个元素subsequence.相反,这样做,

for word in list:
    if subsequence in word:
        OK = True
        break

您可以使用该any()功能将其压缩为一行.这样做,使用,

OK = any(subsequence in word for word in list)
