运行 python 脚本时如何抑制警告？

Question

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

-      : program read from stdin (default; interactive mode if a tty)

Answer 1

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")

Answer 2

It is

-Wignore

without space. fe:

python -Wignore file.py
