Question

编写一个输入JSON文件的程序（格式就像 example1.json）并打印出标题字段的值。

import json

# TODO: Read your json file here and return the contents
def read_json(filename):
    dt = {}
    # read the file and store the contents in the variable 'dt'
    with open(filename,"r") as fh:
        dt = json.load(fh)

    ###fh = open(filename, "r")
    ###dt = json.load(fh)

    return dt


# TODO: Pass the json file here and print the value of title field. Remove the `pass` statement
def print_title(dt):
    print filename["title"]


# TODO: Input a file from the user
filename = raw_input("Enter the JSON file: ")


# The function calls are already done for you
r = read_json(filename)
print_title(r)

嗨，我是Python新手，我不确定我做错了什么。我一直收到以下消息： enter image description here

你几乎就在那里，你只是对参数名称感到困惑。

改变这个：

def print_title(dt):
    print filename["title"]

要：

def print_title(dt):
    print dt["title"]
