The opposite conversion is easy - datetime has a .date() method. Do I really have to manually call datetime(d.year, d.month, d.day) ? 回答1: You can use datetime.combine (date, time); for the time, you create a datetime.time object initialized to midnight. from datetime import date from datetime import datetime d = date.today() datetime.combine(d, datetime.min.time()) 回答2: There are several ways,

I want to get a list of lists or even every list there: [[1,2,3],[10,12,5]] 回答1: You should use literal_eval to get actual list object from string . >>> from ast import literal_eval >>> data = ['[1,2,3]','[10,12,5]'] >>> data = [literal_eval(each) for each in data] >>> data [[1, 2, 3], [10, 12, 5]] literal_eval safely evaluates each object. >>> help(literal_eval) Help on function literal_eval in module ast: literal_eval(node_or_string)
