使用Python读取JSON文件

Question

我对python很陌生，我正在尝试读取一个JSON文件，目前我只需将其写入一个新文件，而不需要进行任何更改。我一直试图使用python包Click来完成这个操作，但始终会遇到错误。

我相信这是比较基本的，但任何帮助都将不胜感激。下面是我尝试过的代码的最新版本。

 import json
 import os
 import click


 def dazprops():
     """Read Daz3D property File"""
     path = click.prompt('Please specify a location for the Daz3D Properties File')
     path = os.path.realpath(path)
     #dir_name = os.path.dirname(path)
     print(path)
     dazpropsf = open('path')
     print(dazpropsf)


 if __name__ == '__main__':
     dazprops()

像这样的东西可以让您知道如何使用click实现这一目标。

import click

def read_file(fin):
    content = None
    with open(fin, "r") as f_in:
        content = f_in.read()
    return content

def write_file(fout, content):
    try:
        print("Writing file...")
        with open(fout, "w") as f_out:
            f_out.write(content)
        print(f"File created: {fout}")
    except IOError as e:
        print(f"Couldn't write a file at {fout}. Error: {e}")

@click.command()
@click.argument('fin', type=click.Path(exists=True))
@click.argument('fout', type=click.Path())
def init(fin, fout):
    """
    FINT is an input filepath
    
    FOUT is an output filepath
    """
    content = read_file(fin)
    if content:
        write_file(fout, content)
                
if __name__ == "__main__":
    init()
