你可以使用两个分割，一个在 - 处，另一个在 , 处
notes = 'sol,250-mi,250-mi,500-fa,250-re,250-re,500-do,250-re,250-mi,250-fa,250'
numbers = [temp.split(',')1 for temp in notes.split('-')]
英文:
You can use two splits, one at - and one at ,
notes = 'sol,250-mi,250-mi,500-fa,250-re,250-re,500-do,250-re,250-mi,250-fa,250'
numbers = [temp.split(',')[1] for temp in notes.split('-')]

你已经差不多完成了。在你的第一个split命令之后，duration是一个字符串列表。
然后，你遍历这些字符串，在每个字符串上调用split，但是用,代替-。
英文:
You're pretty much there already. After your first split command, duration is a list of strings.
Then you iterate over those strings and on each of those you call split again, but with , instead of -.
