找出两个字符串中出现的单词数

Question

我想编写一个代码来比较两个文本并告诉我一些相同的字符（或一些相同的单词） 我怎样才能做到这一点？ 我不想用：

print(text1 == text2)

我除了：

a = "i from israel"
b = "hello i from london"

# *i* and *from* are in both strings = 2

c = "apple orange banana watermelon"
d = "apple is very healthy, also banana and orange"

# *apple* and *banana* and *orange* are in both strings = 3

我想与低加重度进行比较，我的意思是，计算两个字符串中的单词。 谢谢

Answer 1

您可以通过这样做获得相同的单词：list(set(a.split(' ')) & set(b.split(' ')))
