How to create multiple arg variables from Run script python workflow?

[Bhishan]

I was wondering how to create multiple argument variable using python.

After hours of googling I found this link:

 https://www.deanishe.net/post/2018/10/workflow/environment-variables-in-alfred/

 

and I figured out myself.

 

# Create env variables

```python

 

import sys

s = "apple banana; car truck"
lst = s.split(';')

a = lst[0]
b = lst[1]

myjson = """
{"alfredworkflow": {
    "arg": "",
    "variables": {"a": "%s",
                  "b": "%s"
                 }
   }
}
""" % (a,b)

myjson = myjson.strip()

sys.stdout.write(myjson)

```

 

#  Use env variables

```python

import sys,os

arg1 = os.getenv('b')

changed = arg1 + ' called from another object'

sys.stdout.write(changed)

```

It's literally stickied at the top of this forum …

This is a really bad way to create JSON. It's almost impossible to be sure it will be valid. Use the built-in Python module:

import json
import sys

lst = ['some data', 'some more data']

data = {
    'alfredworkflow': {
        'arg': '',
        'variables': {
            'a': lst[0],
            'b': lst[1],
        },
    }
}

json.dump(data, sys.stdout)

Thanks for the suggestion of use of json. I appreciate it.

 

What I meant by spending hours is, I saw your solution, but tried to make it work in python alone and it took me hours.

 

There is much to absorb in the given tutorial (python, applescript and so many things) but not a single stand alone python workflow which is kind of complete.

So, I tried to implement the workflow in python borrowing all the ideas from that link. The link is helpful but its broad and takes some time to filter out.
