Capturing output of python code and exporting into a JSON

Question

I have a file named phone.py which give me output as(in terminal):

+911234567890
+910123321423

There can be more number of outputs.

Another file named email.py which produces(in terminal):

[email protected]
[email protected]

or more.

And I have a JSON File whose structure is as follows:

{"One":"Some data",
 "two":"Some more data",
 "three":"Even more data"}

There can be a many more sections like this.

Now I want the capture the terminal output and also load the existing JSON and finally, have an output as follows (as a JSON file):

{Phone:"+911234567890,+910123321423", "Email":"[email protected],[email protected]","Sections":"{"One":"Some data",
 "two":"Some more data",
 "three":Even more data"}"}

I tried to capture the output using subprocess module in python and now it is stored in a variable

subprocess.run(['python','email.py','filename.txt'], stdout= subprocess.PIPE)

output:

CompletedProcess(args=['python', 'email_txt.py', 'upload/filename.txt'], returncode=0, stdout=b'[email protected]\[email protected]\n')

I have a string in which data is stored not I want the desired output through these components. What can I do or refer to tackle this problem ?

Removing the `bash` tag as it is not an efficient way to construct the required `JSON` — Inian, Apr 06 '17 at 06:28
Producing `"email": ["[email protected]", "[email protected]"]` would seem like a better way to encode this in JSON. — tripleee, Apr 06 '17 at 10:12
Why would you run Python in a subprocess? `import` the script and call its main function from within your own script. This improves cohesion as well as performance. — tripleee, Apr 06 '17 at 10:14

You can obtain the stdout from subprocess.run simply by resp.stdout, where resp is the returned object.

Maybe also mention that the optional argument `universal_newlines=True` will also take care of decoding any output according to the default terminal encoding. – tripleee Apr 06 '17 at 10:12

As already mentioned by Rishav, you need to assign the output to a variable & then use it to get the related attributes.

Sample usage -

>>> import subprocess
>>> out = subprocess.run(["ls", "-l", "/dev/null"], stdout=subprocess.PIPE)
>>> out.stdout
b'crw-rw-rw- 1 root root 1, 3 Apr  6  2017 /dev/null\n'

This is returned as type "bytes", how do i get it as a string ? – anshaj Apr 06 '17 at 06:40
You could use `out.stdout.decode('utf-8')`, as mentioned in http://stackoverflow.com/a/606199/2689986 – shad0w_wa1k3r Apr 06 '17 at 06:42
