You can use str(x).zfill(2) instead of "0"+str(x).

Thank you!! That way is easy to read code My code is edited

Maybe an easier way could be:

from datetime import date month = sys.argv[1] my_date = date(date.today().year, month, 1)

while my_date.month == month: filename = my_date.strftime('%Y%m%d') print filename # write your file
my_date = date.fromordinal( my_date.toordinal() + 1 )

from datetime import date
month = sys.argv[1] 
my_date = date(date.today().year, month, 1)
while my_date.month == month:
    filename = my_date.strftime('%Y%m%d')
    print filename
    # write your file    
    my_date = date.fromordinal( my_date.toordinal() + 1 )
