Python 我怎样才能让一本词典生成两个键相同的词典

我有一本字典，什么

what = {'a': ['b'], 'c': ['d\n', 'e\n', 'f'], 'd': ['f', 'g']}

并且需要将带有“/n”的项目分开，不带“/n”（顺序很重要，需要对值进行排序。）：

这就是我所尝试的：

    def lst(profiles_file: TextIO):
        solve_lst = []
        new_lst = fix_files(profiles_file)
        for k, v in new_lst.items():
            for i in v:
                if i.find('\n') != -1:
                get_index = [v.index(i)]
                solve_lst.append(get_index)
     return solve_lst

我怎样才能在不做任何复杂的事情的情况下得到它呢？

这里有一个使用

    def lst(profiles_file: TextIO):
        solve_lst = []
        new_lst = fix_files(profiles_file)
        for k, v in new_lst.items():
            for i in v:
                if i.find('\n') != -1:
                get_index = [v.index(i)]
                solve_lst.append(get_index)
     return solve_lst

from collections import defaultdict

def lst(profiles_file: TextIO):
    initial_dict = fix_files(profiles_file)

    with_n = defaultdict(list)
    without_n = defaultdict(list)

    for k, v in initial_dict.items():
        for item in v:
            if '\n' in item:
                with_n[k].append(item)
            else:
                without_n[k].append(item)

    return [without_n, with_n]
