小编Lel*_*say的帖子

这是我的代码:

today = datetime.date.today()

if len(sys.argv) > 1:
    arg_month = sys.argv[1]
    arg_year = sys.argv[2]
    print arg_month
    print arg_year
    lastMonth = datetime.date(day=1, month=arg_month, year=arg_year)
    first = lastMonth + datetime.timedelta(month=1)
    lastMonth = lastMonth.strftime("%Y%m")
    curMonth = first.strftime("%Y%m")   
else:
    first = datetime.date(day=1, month=today.month, year=today.year)
    lastMonth = first - datetime.timedelta(days=1)
    lastMonth = lastMonth.strftime("%Y%m")
    curMonth=(time.strftime("%Y%m"))

这就是我运行代码的方式:python lelan.py 01 2015

输出是:

01
2015
Traceback (most recent call last):
  File "lelan.py", line 22, in <module>
    lastMonth = datetime.date(day=1, month=arg_month, year=arg_year)
TypeError: an integer is required

如何解决这个问题？谢谢.
