Getting my Python program to run Power Shell Script

Question

Hello please forgive me if my question duplicate, I've searched previous questions and nothing seems to be quite the same. I'm working on a program that will scan a specific folder and search for specific file types to create a menu for a user to select. Once the user select the menu option the the corresponding file which is a power shell script. Currently My program does everything but run even a simple power shell script. I've attempted several configuration and it's not working. It would be great if someone can see what I may be doing wrong or provide me with some pointers. Code below.

##Text Menu Dynamic test
##version 1
## Created By Dragonshadow
## Code produce in Notpad++ For python v3.4.4
import os
import subprocess
import time
import pathlib
import logging
import fnmatch
import re


## Directory Enumerator
fileFolderLocationFilter = fnmatch.filter(os.listdir('C:\\Users\\myfolder\\Documents\\Automation_Scripts\\ENScripts\\'),"*.ps1")
selectedFile=""


## Menu defined setting veriables
def ENOC_menu():
    files = fileFolderLocationFilter
    counter = 1
    print (20 * "=" , "Enoc Quick Menu" , 20 * "=")
    enumFiles = list(enumerate(files))
    for counter, value in enumFiles:
        str = repr(counter) + ") " + repr(value);
        print(str)
    str = repr(counter+1) + ") Exit";
    print(str)
    print (57 *    "_")
    str = "Enter your choice [1 - " + repr((counter+1)) + "]:"
    choice = int(input("Please Enter a Selection: "))
    selectedFiles = enumFiles[choice]
    return(selectedFiles[1])
    if choice > counter : 
        choice = -1
    elif choice != counter :
        print("Please selecte a valid choice")

    else:
        selectedFiles = enumFiles[choice]
        print(selectedFiles[1])
        ##selectedFiles = selectedFiles[1]
    return choice

def you_sure():
    opt = input("Are you sure Yes or No: ")
    if opt=="Yes":
        print("Continuing please wait this may take a moment...")

    elif opt=="No":
        print("returnig to Enoc Menu")


    else: ##Stays in loop
        print ("Please choose yes or no")

##count_down
def count_down ():
    count_down =  10
    while (count_down >= 0):
        print(count_down)
        count_down -= 1
        if count_down == 0:
            print("Task will continue")

            break



##initiating loop
loop = True
while loop:
    choice = ENOC_menu()
    print ("\n" +"You selected "+ choice +"\n")
    subprocess.call("C:\\WINDOWS\\system32\\WindowsPowerShell\\v1.0\\powershell.exe" + choice, shell=True)
    ##print ("---" +str(selectedFile))

Recently I see an increasing number of questions with code lines wrapped in arbitrary places. Is this a new fad or something? Please don't do that. Post your code *exactly* as it's in your script. — Ansgar Wiechers, Jan 18 '18 at 23:15

Ansgar, I'm not understanding are you saying that I've wrapped my code wrong. I've only asked a few questions and it seemed that I am follow the direction if not can you provide more details so that I can correct my error. — DragonShadow, Jan 19 '18 at 00:09
Does the code you posted look *exactly* like the code in your actual script (for instance lines 15 through 19)? If it doesn't (which is my guess): fix that. We can't help you when code you posted is different from the code that is actually causing the problem. — Ansgar Wiechers, Jan 19 '18 at 00:13
Ansgar - The code in all section is the same. I have a couple of methods that I have not called to in my loop for now as I was working on the ability to call a power shell script. I will admit i'm no where near the best coder but I've tried to provide every thing I'm doing to try and get an answer for what I may be doing wrong. — DragonShadow, Jan 23 '18 at 21:12

You have probably already figured this out, but I the problem is in the subprocess.call() line. You are concatenating the powershell.exe path and the target file name together. See here:

>>> scriptToRun = "c:\\users\\Username\\Documents\\WindowsPowerShell\\classtestscript.ps1"
>>> powershellExe = "c:\\windows\\system32\\windowspowershell\\v1.0\\powershell.exe"
>>> print(powershellExe + scriptToRun)
c:\windows\system32\windowspowershell\v1.0\powershell.exec:\users\Username\Documents\WindowsPowerShell\classtestscript.ps1

Above, the two strings are stuck together without a space between them. Windows can't make sense of what you're trying to execute.

Put a space between the two two and subprocess.call() will understand what you're trying to do:

>>> print(powershellExe + ' ' + scriptToRun)
c:\windows\system32\windowspowershell\v1.0\powershell.exe c:\users\Username\Documents\WindowsPowerShell\classtestscript.ps1
