The groups_per_user function receives a dictionary, which contains group names with the list of users.
Explanation:
The blanks to return a dictionary with the users as keys and a list of their groups as values is shown below :
def groups_per_user(group_dictionary):
user_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 the list of
# groups for this user, creating the entry
# in the dictionary if necessary
user_groups[user] = user_groups.get(user,[]) + [group]
return(user_groups)
print(groups_per_user({"local": ["admin", "userA"],
"public": ["admin", "userB"],
"administrator": ["admin"] }))
