I am trying to suppress warnings.

here is my esri python version

python -V

Python 2.7.16

I have tried this

python.exe -W ignore GET_ESRIGIS_WEB_TOKEN.py

but it gives this error

Invalid -W option ignored: invalid action: '"ignore'

what am I doing wrong?

ps: here is the help (see -W option below)

python.exe -h

-W arg : warning control; arg is action:message:category:module:lineno also PYTHONWARNINGS=arg

usage: python.exe [option] ... [-c cmd | -m mod | file | -] [arg] ...
Options and arguments (and corresponding environment variables):
-b     : issue warnings about comparing bytearray with unicode
         (-bb: issue errors)
-B     : don't write .py[co] files on import; also PYTHONDONTWRITEBYTECODE=x
-c cmd : program passed in as string (terminates option list)
-d     : debug output from parser; also PYTHONDEBUG=x
-E     : ignore PYTHON* environment variables (such as PYTHONPATH)
-h     : print this help message and exit (also --help)
-i     : inspect interactively after running script; forces a prompt even
         if stdin does not appear to be a terminal; also PYTHONINSPECT=x
-m mod : run library module as a script (terminates option list)
-O     : optimize generated bytecode slightly; also PYTHONOPTIMIZE=x
-OO    : remove doc-strings in addition to the -O optimizations
-R     : use a pseudo-random salt to make hash() values of various types be
         unpredictable between separate invocations of the interpreter, as
         a defense against denial-of-service attacks
-Q arg : division options: -Qold (default), -Qwarn, -Qwarnall, -Qnew
-s     : don't add user site directory to sys.path; also PYTHONNOUSERSITE

  • That's strange. `-W ignore` is the proper way to do it. It works on my python2 linux installation if that's any consolation! – tdelaney Jun 18 '20 at 16:34
  • Any chance you've got the wrong `warnings` module? Write a little script that imports and prints `warnings.__file__`. – tdelaney Jun 18 '20 at 16:36
  • Do you have a `PYTHONWARNINGS` environment variable? Perhaps that is misformatted. Maybe there is something odd about this "esri" python build... whatever that is. Its a coursework thing? Maybe they disable it in the their build? – tdelaney Jun 18 '20 at 16:41

Usually python -W ignore file.py should work.

However, you can try adding this to the code as well to suppress all warnings

import warnings
warnings.filterwarnings("ignore")

It is

-Wignore

without space. f.e.:

python -Wignore file.py
