python-3.x - 如何将字符串的每个单词与另一个字符串进行比较。Python

Question

我是 python 新手，我真的很努力解决这个问题。我想查找某个单词是否string1存在于string2. 我需要比较string1with的每个单词string2？

count  = len(string2.split())
print(count)
c=0
string1 = "I had a nice day. Infact, I had a great day! Yes sir."
string2 = "nice great sir day lol"

count  = len(string2.split())
print(count)
c=0

i =1
while i<=count:

  if string2[i].split(" ") in string1.split(" "):
    c+= 1
  i += 1

print(c)

没问题！

string1_words = set(string1.split())
string2_words = set(string2.split())
common_words = string1_words & string2_words
print(common_words)
