我有一個名為lists的串列。
lists = [['Was the indus valley part of the maharashtra empire?',
'Is there such a thing as golden age of indian culture?',
'Is the vedic period the same as the golden age?']]
我想將所有這些句子轉換成不同的串列，如下所示。
new_list = [['Was the indus valley part of the maharashtra empire?'],
['Is there such a thing as golden age of indian culture?'],
['Is the vedic period the same as the golden age?']]
如何將一維串列轉換為二維串列？
uj5u.com熱心網友回復：
使用串列推導，您需要遍歷串列的每個子串列，并[sentence]在遍歷子串列時對每個句子執行操作。
result = [[sentence] for sublist in lists for sentence in sublist]

Numpy 還有一個reshape：
np.array(lists).reshape((-1, 1))
[['Was the indus valley part of the maharashtra empire?']
['Is there such a thing as golden age of indian culture?']
['Is the vedic period the same as the golden age?']]

如果您按照@sahasrara62回答的代碼進行操作。它會給你串列中每個字符的串列。

您可以簡單地為此使用串列推導。
result = [[sentence] for sentence in lists]
# output
[['Was the indus valley part of the maharashtra empire?'], ['Is there such a thing as golden age of indian culture?'], ['Is the vedic period the same as the golden age?']]
