errors using python.exe

AmyKlug — Fri, 25 Apr 2014 20:15:46 GMT

If I run my python code using a text file via python.exe from windows desktop (open with) or task scheduler, is there a way to see if there were any errors? would a try/except work?

A try/except block would do this.
Maybe something along these lines.

import traceback

try:
    Your Code Here

except:
    outfile = open("error.txt","w")
    outfile.write(traceback.format_exc())
    outfile.close()

Thanks that worked!!!!!!

now.......

Do you know of a way to add the error as a message to the python.exe window the code is running and have the window stay open instead of closing? the same as if you run a tool that errors in arcmap and you do NOT check "close this dialog when completed successfully"?

Yep, just use "finally" as part of your try/except/finally block. The finally code executes no matter what after your code goes through the try/except.

import traceback  try:     Your Code Here  except:     traceback.print_exc()  finally:     raw_input("Press any key to close this window")

I just tested this on code with no errors. how can I get the python window only stay open when there are errors?

EDIT: I figured it out

Box stays open with and without errors:


except:
    traceback.print_exc()
    raw_input("ERRORS OCCURRED")

finally:
    raw_input("Update Successful")

Box closes if no errors:

except:
    traceback.print_exc()
    raw_input("ERRORS OCCURRED")
