示例list的代码：
lst = ['b-3', 'a-2', 'c-4', 'd-2'] # result: # ['a-2', 'd-2', 'b-3', 'c-4']
1､使用enumerate()和reversed()实现排序
sorted(lst,key = lambda s : [x if i else int(x) for i,x in enumerate(reversed(s.split("-")))])2､使用zip()和reversed()实现排序
lst = ['b-3', 'a-2', 'c-4', 'd-2']
res = sorted(lst, key=lambda x: tuple(f(a) for f, a in zip((int, str), reversed(x.split('-')))))
# 或者
res = sorted(lst, key=lambda x: (lambda y: (int(y[1]), y[0]))(x.split('-')))
print(res)
['a-2', 'd-2', 'b-3', 'c-4']
3､使用toolz实现排序
from toolz import compose
res = sorted(lst, key=compose(lambda x: (int(x[1]), x[0]), lambda x: x.split('-')))

4､使用for实现排序
# 用list
>>> sorted(lst, key=lambda x: [(int(num), text) for text, num in [x.split('-')]])
['a-2', 'd-2', 'b-3', 'c-4']
# 使用next()
>>> sorted(lst, key=lambda x: next((int(num), text) for text, num in [x.split('-')]))
['a-2', 'd-2', 'b-3', 'c-4']
