path.exists() problem

[CAHinton]

I can't get Python to recognize a folder as existing from a batch file or command line. However it works fine within the debugger. Thanks in advance for help.

here's an example of the batch file failing. The folder is not a symbolic link or on a network drive.

Error:
C:\proj\python\Handle_Final_Test_Logs_V_0.0.3_23_July_2018>Handle_FTLogs_TestProcessor

C:\proj\python\Handle_Final_Test_Logs_V_0.0.3_23_July_2018>python "HFT_V_0.0.3.p
y"  -s "C:\proj\python\Handle_Final_Test_Logs\Test_Data\testSource"  -d "C:\proj
\python\Handle_Final_Test_Logs\Test_Data\testDest"
Source C:\proj\python\Handle_Final_Test_Logs\Test_Data\testSource is not a folde
r

here's the output from the script executing within the debugger:

process C:\proj\python\Handle_Final_Test_Logs_V_0.0.3_23_July_2018\Test_Data\testSource

H180456_2018_0718_162618_periodic_log.sorted.csv

here's the relevant portions of the script:

import os, sys, shutil, datetime, time, argparse, keyboard
from pathlib import Path
# globals
folders = []    # list of new folders
sourceFolder = ''
destFolder = ''

parser = argparse.ArgumentParser(description = 'Handle Final Test Logs')
parser.prog = 'Handle Final Test Logs, V0.0.2'
parser.add_argument('-s', '--src', help="source folder, default current")
parser.add_argument('-d', '--dest', help="dest folder, default current")
parser.add_argument('-w', '--watch', default = False, help="watch source, default process source")
args = parser.parse_args()
# other stuff omitted

# check source folder.
sourceFolder = args.src
if (sourceFolder == None): 
    sourceFolder = os.getcwd()
if os.path.exists(sourceFolder):
    if os.path.isdir(sourceFolder):
        pass
    else:
        print ('Source %s is not a folder' % sourceFolder)
        sys.exit(1)
else:
    print ('Source %s does not exist' % sourceFolder)
    sys.exit(1)

finally, here's the relevant portion of my json file:

        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "stopOnEntry": true,
            "args": [
                "-sC:\\proj\\python\\Handle_Final_Test_Logs_V_0.0.3_23_July_2018\\Test_Data\\testSource",
                "-dC:\\proj\\python\\Handle_Final_Test_Logs_V_0.0.3_23_July_2018\\Test_Data\\testDest",

            ]
        },

[woooee]

Use a forward slash in Python. A "\t" is translated as a tab, not as part of a directory string.

Thanks! I belatedly forgot to menton I was using 3.7 in vscode on Windows 7.

I resolved the issue by adding a space between the option and string in the command line arguments. :

works: python "HFT_V_0.0.3.py" -s "C:\proj\python\HFT_0.0.3\Test_Data\testSource"

doesn't: python "HFT_V_0.0.3.py" -s"C:\proj\python\HFT_0.0.3\Test_Data\testSource"
