Title: 检查两个字符串数组是否相等

class Solution:
    def arrayStringsAreEqual(self, word1: List[str], word2: List[str]) -> bool:
        str1 = ''.join(word1)
        str2 = ''.join(word2)

        return str1 == str2

拼接列表字符串

• 字符串=‘分隔符’.join(列表)

  • 如：

  words=['a','b','c']
  str1=' '.join(words)
  print(str1)
  # a b c
  

  words=['a','b','c']
  str1=''.join(words)
  print(str1)
  # abc
