Question

我正在尝试创建一个Python调度程序，我试图在某一天安排会议。

以下是代码：

timetable = [[""] * 24 for slots in range(7)]

WEEKDAYS = ('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday',     
'Saturday', 'Sunday')

timetable[0][15] = "meeting with Jane"

for day in timetable:
  for i, event in enumerate(day):
    if event:
      print("%s at %02d:00 -- %s" % (WEEKDAYS[day], i, event))

然而，当我运行上面的代码时，我收到一个错误;

Traceback (most recent call last):
  File "C:\Users\workspace\test\2D.py", line 18, in <module>
    print("%s at %02d:00 -- %s" % (WEEKDAYS[day], i, event))
TypeError: tuple indices must be integers, not list

我正打算安排会议安排的日子，例如：周一与简会面或周六与简会面。

我如何打印确切的一天？

好的，问题是在WEEKDAYS[day]中，day是24个事件的列表;您想再次使用enumerate()：

timetable = [[""] * 24 for slots in range(7)]

WEEKDAYS = ('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday',
'Saturday', 'Sunday')

timetable[0][15] = "meeting with Jane"

for j, day in enumerate(timetable):
    # day is a list of 24 entries
    for i, event in enumerate(day):
        if event:
            print("%s at %02d:00 -- %s" % (WEEKDAYS[j], i, event))
