[Leet Code] Check If Two String Arrays Are Equivalent

Leetcode: https://leetcode.com/problems/check-if-two-string-arrays-are-equivalent/

Problem:

Given two string arrays word1 and word2, return true if the two arrays represent the same string, and false otherwise.
A string is represented by an array if the array elements concatenated in order forms the string.

Example:

Input: word1 = ["ab", "c"], word2 = ["a", "bc"]
Output: true
Explanation:
word1 represents string "ab" + "c" -> "abc"
word2 represents string "a" + "bc" -> "abc"
The strings are the same, so return true.

Solution:

class Solution(object):
    def arrayStringsAreEqual(self, word1, word2):
        """
        :type word1: List[str]
        :type word2: List[str]
        :rtype: bool
        """
        word1full = ""
        word2full = ""
for i in range(len(word1)):
            word1full += "".join(word1[i])
        for i in range(len(word2)):
            word2full += "".join(word2[i])
if word1full == word2full:
            return True
        else:
            return False
