Question

我有以下单元格数组：

from datetime import datetime
from datetime import timedelta

def next_month_generator(d):
   while True:
       if d.month == 12:
           # on Dec, need to change year
           d = d.replace(year=d.year+1, month=1)
       else:
           try:
               # get next month, same date
               d = d.replace(month=d.month+1)
           except ValueError:
               # get next month, last months date
               d = date(year=d.year, month=d.month+2, day=1) - timedelta(days=1)
       yield d

start_date=date(2017, 01, 31)
nm = next_month_generator(start_date)
for _ in range(13):
   print(nm.next())

 >> 2017-02-28
 >> 2017-03-28
 >> 2017-04-28
 >> 2017-05-28
 >> 2017-06-28
 >> 2017-07-28
 >> 2017-08-28
 >> 2017-09-28
 >> 2017-10-28
 >> 2017-11-28
 >> 2017-12-28
 >> 2018-01-28
 >> 2018-02-28

如何在特定位置插入另一个字符串？例如，我想将a = {'a', 'b', 'c', 'd'}字符串放在第3位，以获得：

'1'

Answer 1

它可以用与矩阵相同的方式完成：

a = {a{1:2}, '1', a{3:end}}

在Matlab中的单元格数组中的特定位置插入元素
