索引超出范围

Question

我不断收到错误消息IndexError：列表分配索引超出范围

schedule = []
for i in range(18):
  schedule.append( set() )

  schedule[1] = { ('LAR','CP'), ('KCC','JJ'), ('BR','MD') }

这为什么不起作用？

编辑：用于排定[1]，而非排定[18]

Answer 1

将最终分配移出循环。

schedule = []
for i in range(18):
  schedule.append( set() )

schedule[1] = { ('LAR','CP'), ('KCC','JJ'), ('BR','MD') }

做我想做的更简单的方法：

# Make the list of empty sets:
schedule = [set()] * 18
# or
schedule = [set() for _ in range(18)]

# Then you assign the value in the list at index 1 to the set you want:
schedule[1] = { ('LAR','CP'), ('KCC','JJ'), ('BR','MD') }
