Running a Python Script

I have a fully functional Python Script which basically collects big data from a website using its API Key and then saves them as CSV in a local folder. Now my task is to run the script with UiPath.

My
Python Scope properties are-
Input : path = where my .exe file is saved
target= x64
version= Python_36

Load Python Script:
File= where my .py script is saved
output= Load_out

Invoke Python Method
Input Parameters= I am confused about this value as I have multiple functions inside the python script
Instance= Load_out
Name= not sure again , assuming it is the function name that needs to be called ???
output = invoke_out

Get Python Object
Input= invoke_out
TypeArgument= DataTable , as i will have to save it as a CSV file
output= get_outDT

First of all I am getting an error about “Load Python Script: Error loading Python script” and the second problem is how do i give the input parameteres.

PS : the command that i used to run the script with command promt is:

python finance_outlook_main.py --mode hours --from 2020-08 --to 2020-09 --usearchived --outputpath C:\Users\TarifMohammad\Desktop\MocoExport\Export-Dev-Data

How do I integrate this two cases ?

Any suggestions, help would be highly appriciated ,

Thanks

If you just want to run the script, why don’t you use a Start Process activity instead?

Hello @Tarif_Mohammad,
your description looks very good :+1:

Here my Python script for an easy testing:

#-Begin-----------------------------------------------------------------

#-Includes--------------------------------------------------------------
import os

#-Function test---------------------------------------------------------
def test(scriptpath):
  text_file = open(scriptpath + "\\Output.txt", "w")
  text_file.write("Hello World")
  text_file.close()
  return "Hello World"

#-End-------------------------------------------------------------------

Here your description with a few additions:

  • Python Scope properties are-
    Input : path = where your python.exe file is saved
    target= x64
    version= Python_36
    image

  • Load Python Script:
    File= The file name of your .py script, with the full path. In my case I store the Python script in the same folder as the process.
    output= Load_out in your case, in my case PyScript_Load
    image

  • Invoke Python Method
    Input Parameters= The parameters of the function you want to call. In my case the directory where the Python script is stored.
    Instance= Load_out in your case, in my case PyScript_Load
    Name= The function name you want to call, in my case test
    output = invoke_out in your case, in my case PyScript_Output
    image

  • Get Python Object
    Input= invoke_out in your case, in my case PyScript_Output
    TypeArgument= DataTable in your case, in my case String
    output= get_outDT in your case, PyScript_OutputString in my case
    image

In my opinion your description looks very good. To your questions:

  • The Error loading Python script exception occurs in two cases, if the file can’t read or if something is wrong with the Python engine, e.g. wrong version. I tried the standard installation of both versions 3.8.6 x86 and x64 and my example works in both cases without any problems.

  • My example shows the transfer of one parameter, here an example with two parameters:

And here the code:

#-Begin-----------------------------------------------------------------

#-Includes--------------------------------------------------------------
import os

#-Function test---------------------------------------------------------
def test(scriptpath, anotherPar):
  text_file = open(scriptpath + "\\Output.txt", "w")
  text_file.write("Hello World from " + anotherPar)
  text_file.close()
  return "Hello World"

#-End-------------------------------------------------------------------

Hope this answers your questions.

Best regards
Stefan
