如何检查字符串中的任何单词是否与另一个字符串匹配

Question

我正在尝试在Python中找到一些函数，该函数可以帮助我找到两个不同字符串的某些单词匹配项。

例如，我们有2个字符串：

1. “我每天都在打篮球”
2. “篮球是有史以来最糟糕的比赛”

如果在两个字符串中都找到“篮球”，我希望此函数返回true。

Answer 1

您可以找到两个短语中的常用词：

common_words = set(phrase1.split()).intersection(phrase2.split())

您可以通过简单地检查单词是否在common_words集中（例如：if word in common_words: ...）来检查两个短语中是否都包含单词。

您还可以检查此集合有多少个元素。如果len(common_words) == 0则phrase1和phrase2不包含常用词。

Answer 2

l = ["I am playing basketball everyday", "basketball is the worst game ever"]

for x in l:
  print (x)
  if "basketball" in x.lower():
    print (True)

Answer 3

str1 = "I am playing basketball everyday"
str2 = "basketball is the worst game ever"

if "basketball" in str1 and "basketball" in str2:
    print "basketball is in both strings!"
