相信大家都有碰到過這種問題，以讀取檔案方式處理分析檔案
今天舉一個例子，大家都聽過兩隻老虎這首兒歌吧!

def modifySong(songStr) #將標點符號用空自元取代
    for ch in songStr:
        if ch in ".,?"
            songStr = songStr.replace(ch, '')
    return songStr

def wordCount(songCount):
    global mydict
    songList = songCount.split() #將歌曲轉成串列
    print("歌曲串列")
    print(songList)
    mydict = {wd:songList.count(wd) for wd in set(songList)}
    
fn = "song.txt"
with open(fn) as file_Obj:  #開檔
    data = file_Obj.read()  #讀檔
    print("所讀歌曲")
    print(data)

mydict = {} #空字典儲存單字計算結果
print("將字母改成小寫及把標點符號用空自元取代")
song = modifySong(data.lower())
print(song)

wordCount(song) #歌曲單字計算
print("result")
print(mydict)
