Question

Main.py

在我现在的代码中，它只是停留在第一个问题上而没有继续第二个问题。我想让它循环直到回答最后一个问题并且循环将 break/stop.

def main():
    Total = None

    with open("test.json", "r") as f:
        File = json.load(f)

    for i in File["data"].keys():
            Total = i # Total of the keys

    def do_game():
        num = 0
        num += 1

        if num > int(Total):
            print("No more questions are available.")
            return False # To break the loop but didn't work at all

        name = File["data"][str(num)]["type"]

        print("Enter type of filename (#{}) :".format(num))
        answer = input("Answer: ")

        if answer == name:
            print("Correct!")
        else:
            print("Incorrect!")

    while True:
        do_game() # I tried to loop this but didn't go well

main()

test.json

{
    "questions": {
        "1": {
            "question": "Video.mp4",
            "answer": "mp4"
        },
        "2": {
            "question": "cool.gif",
            "answer": "gif"
        },
        "3": {
            "question": "main.py",
            "answer": "python"
        }
    }
}

Answer 1

尝试将循环调整为：

while True:
    result = do_game()
    if result == False:
        break

Answer 2

你可以试试这个：

def main():
    Total = None

    with open("test.json", "r") as f:
        File = json.load(f)

    for i in File["data"].keys():
            Total = i # Total of the keys

    num = 1

    while num <= int(Total):

        name = File["data"][str(num)]["type"]

        print("Enter type of filename (#{}) :".format(num))
        answer = input("Answer: ")

        if answer == name:
            print("Correct!")
        else:
            print("Incorrect!")

        num += 1

main()

因为你的数据是从1开始计数所以我们设置num = 1.

您的代码根本就不是运行 question 1 和 2（这是您数据的前 2 项）。它不会对文件进行任何循环。

Answer 3

您需要修改代码。试试这个，

import json
def main():
    with open("test.json", "r") as f:
        File = json.load(f)
    total = len(File['questions'])
    for i in range(1,total+1):
        name = File["questions"][str(i)]["answer"]
        print("Enter type of filename (#{}) :".format(i))
        answer = input("Answer: ")
        print("Correct!" if answer==name else "Incorrect!")
    else:
        print("No more questions are available.")
        return False # To break the loop but didn't work at all

main()

输出：

Enter type of filename (#1) :
Answer: mp4
Correct!
Enter type of filename (#2) :
Answer: m
Incorrect!
Enter type of filename (#3) :
Answer: s
Incorrect!
No more questions are available.

Answer 4

您的代码中有许多小错误。
这是一个有一些改进的功能代码。它们在代码中写为注释。

import json 

def do_game(jsonFile): #You need to put this function outside the main

    for question in jsonFile["questions"]: # Use a for loop over the json list
        filename = question["question"]

        print(f"Enter type of filename '{filename}'") #Use F-String
        answer = input("Answer: ")

        print("Correct!" if answer==question["answer"] else "Incorrect!")


def main():
    Total = None

    with open("test.json", "r") as f:
        jsonFile = json.load(f)

    do_game(jsonFile) # Do all the game's code in a function

# It's a good practice to execute the main funciton only if this file is the main file
if __name__ == "__main__": 
    main()

由于您有问题列表，请在 json

中使用列表

{
    "questions": [
        {
            "question": "Video.mp4",
            "answer": "mp4"
        },
        {
            "question": "cool.gif",
            "answer": "gif"
        },
        {
            "question": "main.py",
            "answer": "python"
        }
    ]
}
