Python - String列表Newline

Question

是否有一种方法可以将列表项与\n序列分开？下面是代码：

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'添加到列表或打印时，如下所示：

print month_names + '\n'

或

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

语法或类型错误引发，有时它会打印\n。

期望的输出是：

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

我想把它作为一个列表来保存，这样我就可以回忆起第二个列表，比如：

'April', 'May', 'June' 

Answer 1

我相信你想要的是一个简单的个别月和新线的连接。

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

如果您想要每行的25美分，下面的一个应该可以工作

>>> 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']
