使用 Python 点击​​读取 JSON 文件

Question

I am new to python and I am trying to read in a JSON file, that for now I can just write out to a new file without any changes. I have been attempting to use the python package Click to do this but keep running into errors.

I'm sure this is relatively basic but any help would be appreciated. The latest version of the code I've tried is below.

 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()

Something like this could give you an idea how to achieve that using click :

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()
