我在附加現(xiàn)有詞典的值時(shí)遇到問題。目標(biāo)是打開一個(gè) json 文件，分析現(xiàn)有的字典，查看是否存在任何服務(wù)，如果該服務(wù)存在，則附加新密碼。#!/usr/bin/env python3import jsonimport random#a set of characters to chose from for the passwordschar = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()\{\}[]-_=+/?.>,<|`~'services = []passlength = 0b = 0#this function takes your input on what services you want in your list of dictionariesdef service_add():    serviceques = input('what service is the password for? ')    service = (serviceques)    if service == 'done':        starter()    elif service == '':        print('you must enter a service name')        service_add()    elif service == ' ':        print('you must enter a service name')        service_add()    else:        if service in services:            print('service and key already exists')        else:            services.append(service)            #print(services)        service_add()#function to tell how long you want your password to bedef starter():    lengths = input('How long do you want the password to be? ')    global length    length = int(lengths)    makingPairs()#this function creates a password and puts the password in a dictionary with each #service in your list then appends the set of service and password to a json filedef makingPairs():      global b    global services    global length          a = 0    jsondics= []    for line in services:        a = a + 1    for x in range(a):        password = ''             for c in range(length):            password += random.choice(char)                jsonpairs = {            'Service' : services[b],            'Password' : password        }這是來自 json 文件的原始數(shù)據(jù)[{"Service": "spotify", "Password": "5QF50W,!UG"}, {"Service": "pandora", "Password": "E=b]|6]-HJ"}]當(dāng)我運(yùn)行代碼并嘗試刪除“潘多拉”時(shí)，它給了我這個(gè)例子[{'Service': 'spotify', 'Password': 'bMXa2FY%Rh'}, {'Password': '$m--c<CY2x'}]問題是，它沒有刪除整個(gè)字典，而是只刪除了名為“Pandora”的鍵。我試圖更改new_list變量，但它仍然只刪除鍵或值，而不是整個(gè)變量。
