reader =csv.reader(f) enrollments=[row for row in reader] print enrollments #返回的类型都是:list out: [['account_key', 'status', 'join_date', 'cancel_date', 'days_to_cancel', 'is_udacity', 'is_canceled'], ['448', 'canceled', '2014-11-10', '2015-01-14', '65', 'True'...
The exercise instructions provide a code snippet that we can cut and paste into our solution. It defines a variable named numbers, which is assigned a list of elements, and each element is a nested list of integers. Now I need to open a file for…
