파이썬 복습 + json xml, yaml,

0830수업 중 실습

 

사전 key value 뒤집은 값도 저장

english_dict = dict()
english_dict['one']='하나'
english_dict['two']='둘'
english_dict['three']='셋'
korean_dict = {v:k for k,v in english_dict.items()}
word = input("단어를 입력하시오:")
if word in english_dict:
    print(english_dict[word])
elif word in korean_dict:
    print(korean_dict[word])
else:
    print('없음')

 

 

연락처 만들기 - dict의 key를 rename하는, choice4주목

friends = []
select = 0
while select != 9:
    print("----------")
    print("1. 친구 리스트 출력\n2. 친구추가\n3. 친구삭제\n4. 이름변경\n9. 종료")
    
    choice = int(input("메뉴를 선택하시오 : "))
    if choice == 1:
        print(friends)
    
    elif choice == 2:
        name = input("이름을 입력하시오 : ")
        friends.append(name)
   
    elif choice == 3:
        name = input("삭제할 이름을 입력하시오 : ")
        if name in friends:
            friends.remove(name)
        else: print("해당 이름은 없습니다.")
    
    elif choice == 4:
        name = input("변경하고 싶은 이름을 입력하시오 : ")
        if name in friends:
            new_name = input("새로운 이름을 입력하세요 : ")
            friends[friends.index(name)]= new_name  
        else: print("해당 이름은 없습니다.")

파이썬으로 json파일 생성 

import json 
car_group = dict()

k5 = dict()
k5["price"] = "5000"
k5["year"] = "2015"
car_group["K5"] = k5

avante = dict()
avante["price"] = "3000"
avante["year"] = "2014"
car_group["Avante"] = avante

#json 파일로 저장
with open('C://users/playdata/test2.json', 'w', encoding='utf-8') as make_file:
    json.dump(car_group, make_file, indent="\t")

# 저장한 파일 출력하기
with open('C://users/playdata/test2.json', 'r') as f:
    json_data = json.load(f)

print(json.dumps(json_data, indent="\t") )

json - dict 저장

 

import json
car_group = dict()


k5 = dict()
k5["price"] = "5000"
k5["year"] = "2015"
car_group["K5"] = k5


avante = dict()
avante["price"] = "3000"
avante["year"] = "2014"
car_group["Avante"] = avante



#json 파일로 저장
with open('C:\\test.json', 'w', encoding='utf-8') as make_file:
    json.dump(car_group, make_file, indent="\t")
	

# 저장한 파일 출력하기
with open('C:\\test.json', 'r') as f:
    json_data = json.load(f)
print(json.dumps(json_data, indent="\t") )

출력문 :
{
	"K5": {
		"price": "5000",
		"year": "2015"
	},

	"Avante": {
		"price": "3000",
		"year": "2014"
	}
}
