Python比较文本

Question

我想编写一个代码，在两个文本之间进行比较，并告诉我一些相同的字符（或某些相同的单词）我怎样才能做到这一点？我不想使用：

print(text1 == text2)

i除了类似的东西：

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

我想比较低沉重度，我的意思是，计算两个字符串中的单词。谢谢

Answer 1

您可以通过执行以下操作获得相同的单词：list(set(a.split(' ')) & set(b.split(' ')))
