用函数统计一歌词(文章、小说)中单词出现的次数，替换标点符号为空格，用空格进行分词。

str = '''
I've been reading books of old
The legends and the myths
Achilles and his gold
Hercules and his gifts
Spiderman's control
And Batman with his fists
And clearly I don't see myself upon that list
She said where'd you wanna go
How much you wanna risk
I'm not looking for somebody
With some Superhuman gifts
Some Superhero
Some fairytale bliss
Just something I can turn to
Somebody I can kiss
I want something just like this
Doo doo doo doo doo doo'''
print(str.count("my"))
print(str.count("you"))
print(str.count("and"))
print(str.count("kiss"))
print(str.replace(","," "))
