1.looping with keys
for each_key in dictionary:

bts_rm = { "실명" : "김남준", "가명" : "랩몬", "출생" : 1991 }

for each_key in bts_rm:
    print(f"{each_key}")

실명
가명
출생

2.looping with values
for each_value in dictionary.values():

bts_rm = { "실명" : "김남준", "가명" : "랩몬", "출생" : 1991 }

for each_value in bts_rm.values()
    print(f"{each_value}")

김남준
랩몬
1991

3.looping with keys and values
for each_key, each_value in dictionary.itmes() : returns each_key and each_value in a tuple format

bts_rm = { "실명" : "김남준", "가명" : "랩몬", "출생" : 1991 }

for each_key, each_value in bts_rm.items()
    print(f"{each_key}: {each_value}")

실명: 김남준
가명: 랩몬
출생: 1991

4.list of dictionaries and nested dictionaries are possible

my_list = [
    {1: "name",

    },
    {3: "who",
     4: "are",
     5: "you?"

my_dict = {
    {1: "name",
