Traceback (most recent call last):
File …我试图从用户获取输入日期并以形式存储它
dt_start = dt.datetime(2006, 1, 1)
我目前正在这样做:
i = str(raw_input('date'))
dt_start = dt.datetime(i)
但它抛出一个错误:
Traceback (most recent call last):
File "C:/.../sim.py", line 18, in <module>
dt_start = dt.datetime(i)
TypeError: an integer is required
谢谢你的帮助!
