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

Let it go

Let it go

Can't hold you back anymore

Let it go
Let it go
Turn my back and slam the door
.

The snow blows white on the mountain tonight
Not a footprint to be seen

A kingdom of isolation and it looks like I'm the Queen

The wind is howling like the swirling storm inside

Couldn't keep it in, heaven knows I tried

Don't let them in, don't let them see
Be the good girl
You always had to be
Conceal, don't feel
Don't let them know

Well, now they know
.
Let it go
Let it go

Can't hold you back anymore

Let it go
Let it go

Turn my back and slam the door

And here I stand, and here I'll stay
Let it go
Let it go

The cold never bothered me anyway
.
It's funny how some distance

Makes everything seem small

And the fears that once controlled me
Can't get to me at all

Up here in the cold thin air
I finally can breathe

I know i left a life behind but I'm to relieved to grieve
.
Let it go
Let it go

Can't hold you back anymore

Let it go
Let it go
Turn my back and slam the door

And here I stand

And here I'll stay

Let it go
Let it go

The cold never bothered me anyway
.
Standing frozen in the life I've chosen

You won't find me, the past is so behind me

Buried in the snow
.

Let it go
Let it go

Can't hold you back anymore

Let it go
Let it go

Turn my back and slam the door

And here I stand

And here I'll stay

Let it go
Let it go

The cold never bothered me anyway

na na na na na na
Let it go na na na

you go

Let it go
Let it go

Let it go

1 print(str.count("go"))
2 print(str.replace(","." "))
