JQ 命令在 python 中不起作用

Question

So I have a jq command that converts my json array into a json object. The command works normally in the windows terminal, but when I try to implement it into my python program i get this: jq: error:

Could not open file >newfile.json: Invalid argument.

Here is my jq command which works and puts the transformed json into newfile.json:

jq ".[]" data.txt >newfile.json

Here is my subprocess call in my python program:

 subprocess.call('jq ".[]" data.txt >newfile.json', cwd=r'C:/Users/john/Desktop/swag', shell=True)

Answer 1

Open the output file yourself, and you won't need to rely on shell behavior (which is, obviously, not working in the present case) to do it for you.

subprocess.call(['jq', '.[]', 'data.txt'],
  cwd=r'C:/Users/john/Desktop/swag',
  stdout=open('C:/Users/john/Desktop/swag/newfile.json', 'w'))
