Question

有没有办法用 \n 顺序分隔列表项？这是代码：

month_names = [
                ['January', 'February', 'March'],
                ['April', 'May', 'June'],
                ['July', 'August', 'September'],
                ['October', 'November', 'December'],
                ]   
print month_names

问题是当我尝试将 \n 或 '\n' 添加到列表或像这样打印时：

print month_names + '\n'

或

['January', 'February', 'March'], '\n',

出现语法或类型错误，有时会打印 \n。

期望的输出是：

'January', 'February', 'March'
'April', 'May', 'June'
'July', 'August', 'September'
'October', 'November', 'December'

我想将它保留为一个列表，这样我就可以像这样回忆第二个列表：

'April', 'May', 'June'

我相信你想要的是用换行符简单地连接各个月份

>>> print '\n'.join(map('\n'.join, month_names))
January
February
March
April
May
June
July
August
September
October
November
December

以防万一，您希望每一行都有四分之一，以下方法之一应该可行

>>> print '\n'.join(map(' '.join, month_names))
January February March
April May June
July August September
October November December

>>> print '\n'.join(map(str, month_names))
['January', 'February', 'March']
['April', 'May', 'June']
['July', 'August', 'September']
['October', 'November', 'December']
