groups_per_user 函数接收一个字典,其中包含带有用户列表的组名。就像 Linux 系统中的组。用户可以属于多个组。填空以返回一个以用户为键、以用户组列表为值的字典。
基本上我试图将组分配给用户而不是用户分配给组
def groups_per_user(group_dictionary):
user_groups = {}
groups = []
# Go through group_dictionary
for group,users in group_dictionary.items():
# Now go through the users in the group
for user in users:
# Now add the group to the list of
# groups for this user, creating the entry
# in the dictionary if necessary
groups.append(group)
user_groups[user] = group
return(user_groups)
print(groups_per_user({"local": ["admin", "userA"],
"public": ["admin", "userB"],
"administrator": ["admin"] }))

如何遍历抛出列表,同时尽可能高效地将用户添加到组名中?
请原谅我的语法,这是我的第一个问题。谢谢
