Simple UI to run script2 + args

[iApeiron]

Can anybody point me in the right direction?
I'm hoping to find a basic template or example.

I need a script1.py to run "script2.py arg1 arg2 arg3"
I'm new to Pythonista, and not sure where to start.
Thank you!

Hi,

welcome to Python(ista)! You could use exec (see here) to do what you have described. But using exec is usally considered really bad style for a reason as it WILL open the doors to purgatory at some point. Is there any reason why you could not do what you want to do with a normal module?

[iApeiron]

Thank you. This is a start. But I also need some way to append user input as arguments for script2.
Essentially, a GUI wrapper for a pre-existing commandline .py

You could just modify sys.argv in the first script, then use runpy.run_path to run the second.

@omz Thank you. I think I have a start now, thanks to coming across this ex13-raw_input.py

[iApeiron]

@omz I've got this working based on the ex13 script

from sys import argv

script2 = argv

first_name = raw_input("What is your first name? ")

middle_name = raw_input("What is your middle name? ")

last_name = raw_input("What is your last name? ")

print "Your full name is %s %s %s." % (first_name, middle_name, last_name)

But I have not got runpy to cooperate.
And this doesn't use the 'raw_input' which I need.

Do you have a solution? Thank you for your help

    raw_input          # Python 2
except NameError:
    raw_input = input  # Python 3

script2 = sys.argv[1] if sys.argv[1:] else 'script2.py'
first_name = raw_input("What is your first name? ").strip() or 'Donald'
middle_name = raw_input("What is your middle name? ").strip() or 'J.'
last_name = raw_input("What is your last name? ").strip() or 'Trump'
fmt = "%s: Your full name is %s %s %s."
print(fmt % (sys.argv[0].split('/')[-1], first_name, middle_name, last_name))
runpy.run_path(script2, init_globals={'first_name': first_name,
                                      'middle_name': middle_name,
                                      'last_name': last_name})


"""script2.py
import sys
fmt = "{}: Your full name is {first_name} {middle_name} {last_name}."
print(fmt.format(sys.argv[0], **globals()))
"""

@ccc Thank you for the thoughtful answer!

I think this discussion has strayed away from my original intention.

To rephrase my original intention:
A have a command line Python script which would be used as follows "python main.py arg1 arg2 arg" and then proceeds to do and print some predefined functions.
Now, I want use a wrapper script to run main.py with the args input via a prompt, and print what main.py is doing.

Thank you for help!

with open(sys.argv[0]) as in_file:
    exec(in_file.read())  # exec() is a security hole a mile wide and 10 miles deep!!

"""script2.py

print("{}: Your full name is {} {} {}.".format(*sys.argv))

Python 3 fix also merged into upstream... https://github.com/mwarkentin/Learn-Python-The-Hard-Way/pull/2/files

Uh, I didn't know that python had a short hand syntax for conditional assignments evaluating forTrue. That is nice 👍🏻.

rich,
Are you aware that you long-press the play button for a script, it lets you define arguments? Just checking, not everyone realizes this.

another option would be to use a dialogs popup rather than raw_input

import dialogs
fields=[{'title':'First Name','type':'text'},
         {'title':'Last Name','type':'text'},
         {'title':'Age','type':'number'}]
response=dialogs.form_dialog('What is your info?',fields)

[iApeiron]

@JonB Thanks. I really like this dialogue box! If I can get the responses to act as args to control my second script, then I have it made!

Put that text at the end into a file called script2.py ;-). Then run the rest of the code in a separate file that I called script1.py.

[iApeiron]

@ccc Thanks. I still get the traceback error "AttributeError: 'tuple' object has no attribute 'remove'"

[ccc]

Try changing this line:

sys.argv = ['script2.py', first_name, middle_name, last_name]

To have square brackets [] instead of parentheses ().

@ccc Thank you! This works as expected!
The first two args are necessary, the third arg is supposed to be optional. In its current form, (with Trump removed of course,) leaving the third arg blank causes script2 error (citing an invalid arg).
Do you know how to leave an arg as optional?
