Question

我想分配

1->March 
2->April 
3->May 
11->January 
12->February 

我怎样才能做到这一点在Python？

Answer 1

>>> from datetime import datetime 
>>> {datetime(year=2015, month=x, day=1).strftime('%B'): 1 + (x - 3) % 12 for x in range(1, 13)} 
{'April': 2, 
'August': 6, 
'December': 10, 
'February': 12, 
'January': 11, 
'July': 5, 
'June': 4, 
'March': 1, 
'May': 3, 
'November': 9, 
'October': 8, 
'September': 7} 

Answer 2

import calendar 
{1 + (i - 3) % 12:calendar.month_name[i] for i in range(1, 13)} 

它的输出是

{1: 'March', 
2: 'April', 
3: 'May', 
4: 'June', 
5: 'July', 
6: 'August', 
7: 'September', 
8: 'October', 
9: 'November', 
10: 'December', 
11: 'January', 
12: 'February'}
