给定一组字符串，编写一个Python函数来查找最常见的单词。

strings = "I love coding with Python because Python is easy to learn."
```
def most_common_word(strings):
    word_list = strings.split()
    word_count = {}
    for word in word_list:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1
    return max(word_count, key=word_count.get)

strings = "I love coding with Python because Python is easy to learn."
print(most_common_word(strings))
```
输出： Python
