Question

好的，我有一个数据库程序。除了我的搜索功能之外，我现在已经实现了所有工作，它似乎打印出所有子数组而不是搜索到的数组。我无法确定问题所以我希望你们能以某种方式帮助我解决问题。感谢所有的帮助！

我的代码：

import json
import time

datastore = json.load(open("file.json"))
menuon = 1


def add_user():
    userdata = input("How many users do you wish to input?")
    print("\n")

    if (userdata == 0):
        print("Thank you, have a nice day!")

    else:
        loop = int(userdata)
        whileloop = loop+loop

        while loop < whileloop:
            appendnumber = json.load(open("fileappend.json"))
            loop = loop + 1
            datastore.append([])
            datastore[appendnumber].append(input("Enter Name: "))
            datastore[appendnumber].append(input("Enter Email: "))
            datastore[appendnumber].append(input("Enter DOB: "))
            appendnumber = appendnumber + 1
            json.dump(appendnumber, open("fileappend.json", "w"))


def print_resource(array):
    for entry in datastore:
        print("Name:  "+entry[0])
        print("Email:  "+entry[1])
        print("DOB:  "+entry[2])
        print("\n")


def search_function(value):
  for eachperson in datastore:
      if value in eachperson:
          print_resource(eachperson)


while menuon == 1:        
    print("Hello There. What would you like to do?")
    print("")
    print("Option 1: Add Users")
    print("Option 2: Search Users")
    print("Option 3: Replace Users")
    print("Option 4: End the program")
    menuChoice = input()

    if menuChoice == '1':
        add_user()

    if menuChoice == '2':
        searchflag = input("Do you wish to search the user data? y/n")
        if(searchflag == 'y'):
            criteria = input("Enter Search Term: ")
            search_function(criteria)

    if menuChoice == '3':
        break

    if menuChoice == '4':
        print("Ending in 3...")
        time.sleep(1)
        print("2")
        time.sleep(1)
        print("1")
        json.dump(datastore, open("file.json", "w"))
        menuon=0

file.json包含：

"[["Brandon Jones", "FluxDZ@hotmail.co.uk", "01/07/1999"],]"

fileappend.json包含： 1

问题不在于您的搜索功能，而是您的打印功能：

def print_resource(array):
    for entry in datastore:
        print("Name:  "+entry[0])
        print("Email:  "+entry[1])
        print("DOB:  "+entry[2])
        print("\n")

您传递了一个参数array，但它完全忽略了该参数，而是遍历整个数据存储区中的每个条目，并将它们全部打印出来。

试试这个：

def print_resource(entry):
    print("Name:  "+entry[0])
    print("Email:  "+entry[1])
    print("DOB:  "+entry[2])
    print("\n")

我的数组（子数组）的搜索功能似乎出现故障
