【问题标题】：How to use loop when data type is dictionary数据类型为字典时如何使用循环
【发布时间】：2025-12-20 06:15:15
【问题描述】：

suspect = {'Height':6,'Colour':'Fair','Residency':'Pune'}
Name = input('Please enter your name')
Verification = int(input('Please enter Height ')

if Verification == suspect['Height']:
    print('Suspect is detected  for 1st level')
else:
    print('Suspect is not detected  for 1st level')**

请注意，我的情况是：如果使用{'Height': 3, 'Colour': 'Fair', 'resident': 'Pune'}-condition 检测到suspect，则应保存名称并继续运行代码。意思是'Please enter your name'和'Please Enter Height'应该继续问。

【问题讨论】：

如果没有检测到嫌疑人怎么办？它应该继续运行你的代码吗？

【解决方案1】：

您需要使用 while 循环。在每个循环中，程序都会询问您是否要继续。此外，列表允许存储嫌疑人的姓名

suspect = {'Height':6,'Colour':'Fair','Residency':'Pune'}


suspect_list = []
continu = "Y"
while(continu == "Y"):
    Name = input('Please enter your name: ')
    Verification = int(input('Please enter Height: '))
    if Verification == suspect['Height']:
        print('Suspect is detected  for 1st level')
        suspect_list.append(Name)
    else:
        print('Suspect is not detected  for 1st level')
    continu = str(input("Do you want continu (Y/N): "))

【解决方案2】：

这应该可以解决它：

使用list(dict) 获取所有键值。

代码

//#colour --> color
suspect = {"Name":"Obama","Height":6,'Color':'Black','Residency':'Pune'}

//#List on a dict gives all key strings
suspect_depictions =(list(suspect))

floor = 1
run = True
while run:
    //#Enter info
    Name = input('Please enter your name: ')
    Height = int(input('Please enter Height: '))
    Color = input('Please enter your color: ')
    Residency = input('Please enter your residency: ')
    Still_a_suspect = True

    //#Check all depictions
    for depiction in suspect_depictions:
        if depiction == "Name":
            if suspect[depiction] == Name:
                print("Name match")
            else:
                print("Name dose not match")
                Still_a_suspect = False

        if depiction == "Height":
            if suspect[depiction] == Height:
                print("Height match")
            else:
                print("Height dose not match")
                Still_a_suspect = False

        if depiction == "Color":
            if suspect[depiction] == Color:
                print("Color match")
            else:
                print("Color dose not match")
                Still_a_suspect = False

        if depiction == "Residency":
            if suspect[depiction] == Residency:
                print("Residency match")
            else:
                print("Residency dose not match")
                Still_a_suspect = False

    if Still_a_suspect:
        run = False
        print("The suspect lives on the " +str(floor) + "th floor!")
    else:
        floor += 1
        print("")
        print("------------------------")
        print("")
