How can I create a list of dates for months over several years?

Step-by-step guide

If we want to create a list of dates such as [19930601, 19930701, ..., 20160701, 20160801], where for each year we have the first day of the same months, the following code snippet will create such a list:

1. d1 = 1993-06-01
   d2 = 2016-08-01
   d = d1
   datelist = []
   while d <= d2 do
       datelist = datelist & [d]
       d = addmonths(d, 12)
   end while
   print(datelist)

   import metview as mv
   from datetime import datetime
   
   d1 = datetime(1993,6,1)
   d2 = datetime(2016,8,1)
   d = d1
   datelist = []
   while d <= d2:
       datelist.append(d)
       d = mv.addmonths(d, 1)
   
   print(datelist)
