如何使用Python高效地在另一个字符串列表中搜索字符串列表？

我有两个名称（字符串）列表，如下所示：

executives = ['Brian Olsavsky', 'Some Guy', 'Some Lady']

analysts = ['Justin Post', 'Some Dude', 'Some Chick']

我需要找到这些名称出现在如下所示的字符串列表中的位置：

str = ['Justin Post - Bank of America',
 "Great. Thank you for taking my question. I guess the big one is the deceleration in unit growth or online stores.", 
"I know it's a tough 3Q comp, but could you comment a little bit about that?",
 'Brian Olsavsky - Amazon.com',
 "Thank you, Justin. Yeah, let me just remind you a couple of things from last year.", 
"We had two reactions on our Super Saver Shipping threshold in the first half." ,
 "I'll just remind you that the units  those do not count",
 "In-stock is very strong, especially as we head into the holiday period.",
 'Dave Fildes - Amazon.com',
"And, Justin, this is Dave. Just to add on to that. You mentioned the online stores.

我需要这样做的原因是这样我可以将对话字符串连接在一起（由名称分隔）。我该如何有效地做到这一点？

我查看了一些类似的问题并尝试了无济于事的解决方案，例如：

if any(x in str for x in executives):
    print('yes')

和这个 ...

match = next((x for x in executives if x in str), False)
match

我不确定这是否是您正在寻找的：

executives = ['Brian Olsavsky', 'Some Guy', 'Some Lady']
text = ['Justin Post - Bank of America',
 "Great. Thank you for taking my question. I guess the big one is the deceleration in unit growth or online stores.", 
"I know it's a tough 3Q comp, but could you comment a little bit about that?",
 'Brian Olsavsky - Amazon.com',
 "Thank you, Justin. Yeah, let me just remind you a couple of things from last year.", 
"We had two reactions on our Super Saver Shipping threshold in the first half." ,
 "I'll just remind you that the units  those do not count",
 "In-stock is very strong, especially as we head into the holiday period.",
 'Dave Fildes - Amazon.com',
"And, Justin, this is Dave. Just to add on to that. You mentioned the online stores."]

result = [s for s in text if any(ex in s for ex in executives)]
print(result)

输出： [“布莱恩·奥尔萨夫斯基 - Amazon.com”]
