Validate JSON file

[BellaMac]

Hi, I am new to the python language (well new to any programming language). From what I have been reding on-line, python has components to validate JSON files, which is what I need to do. In stalled Python 3.81 and found a script on-line that says it will validate a JSON file, however, It is not working for me as I think I am not using it correctly

Here is the code in the script

import json

def parse(text):
    try:
    with open("C:\python-script\file\assetLink_tr-TR.json") as f:
    return json.load(f)
    except ValueError as e:
        print('invalid json: %s' % e)
        return None # or: raise

Here is the error i get when i run the script on the CMD

File "C:\python-script\JSON_Validate.py", line 5
with open("C:\python-script\file\assetLink_tr-TR.json") as f:
^
IndentationError: expected an indented block

I appreciate any help

You need to indent the line starting "with"

try:
    with open("C:\python-script\file\assetLink_tr-TR.json") as f:
    return json.load(f)

Thanks for the reply, but now getting the error for the "return json.load(f)" line of code.

This is what i changed the code to

import json
 
def parse(text):
    try:
        with open("C:\python-script\file\assetLink_tr-TR.json") as f:
        return json.load(f)
    except ValueError as e:
        print('invalid json: %s' % e)
        return None # or: raise

This is the new error
File "C:\python-script\JSON_Validate.py", line 6
return json.load(f)
^
IndentationError: expected an indented block

if the indentation is still wrong, can you please indent the 9 lines so i see where i am going wrong.

Once again, thanks for your help

import json
  
def parse(text):
    try:
        with open("C:\python-script\file\assetLink_tr-TR.json") as f:
            return json.load(f)
    except ValueError as e:
        print('invalid json: %s' % e)
        return None

All statements with a colon at the end, introduce a block.
You've to indent the block.

def foo():
    ...

with open("file") as fd:
    ...


if False:
    ...
elif False:
    ...
else:
    ...


while True:
    ...


for i in range(10):
    ...


class:
    ...  # code block of class
    # one method in the code block
    def __init__(self):
        ...  # code block of method __init__

Thanks, for the help with the Indenting.

However, the validation does not work as expected. When i run the script, it does not throw up an exception regarding issues in the JSON file as i know there are issues in the file as i tested the file on an online JSON validation tool.

Do i need to add more to the code so to the script will list the issues.

Thanks

[BellaMac]

Can anyone help me with the code.

Much appreciated.

First you wanted to catch the Exception and now you don't want to catch it?
If a ValueError occurs, the function return None.
If no ValueError happens, then you get the result.

[BellaMac]

Hi, I do want to catch the exception (I apologise if I have confused you), I want the script to tell me what line has the issue as what occurs when validating online.

But when I run the script using the CMD line, nothing happens, nothing gets displayed.

Thanks

nothing happens, nothing gets displayed.

show your code in python tags. What DeaD_EyE show you is a function, but in his snippet the function is never called

[BellaMac]

This is the code in the script as what I posted previous

import json
   
def parse(text):
    try:
        with open("C:\python-script\file\assetLink_tr-TR.json") as f:
            return json.load(f)
    except ValueError as e:
        print('invalid json: %s' % e)
        return None

Thanks
