Python-Pandas DataFrame中的KeyError

Question

當我導入該數據集時：

dataset = pd.read_csv('lyrics.csv', delimiter = '\t', quoting = 2)

它像這樣打印：

                                 lyrics,classification

如果我print (dataset.columns) ，我得到：

Index([u'lyrics,classification'], dtype='object')

但是如果我嘗試打印歌詞，就像這樣：

for i in range(0, len(dataset)):
    lyrics=dataset['lyrics'][i]
    print lyrics

我收到以下錯誤：

KeyError: 'lyrics'

我在這里想念什么？

Answer 1

由於將定界符設置為制表符（\\ t），因此不會像您想象的那樣解析標頭。 “歌詞，分類”是一列名稱。 如果要將定界符保留為制表符，那么在歌詞和分類之間應該有一個制表符而不是逗號。
