Disabling Python Warnings with Command

In case the contents of the code can’t be modified to integrate the previous method into it, warnings can be disabled from the outside. This is done by passing the ignore argument to the -W switch of the Python compiler. 

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

Hence, by integrating the -W “ignore” string in the command to execute the first code, the warnings in the code could be disabled. The code that is to be run from the command line would be:

py -W "ignore" test.py

The Python interpreter is instructed to disable the warnings before the execution of the test.py file (used in the first example). Similarly, using the following syntax:

py -W "ignore" "_filename_"

Warnings could be ignored during the execution of files containing Python code.

There are times when the compiler informs the user of a condition in the program while the code is being executed. When it is necessary to advise the user of a program condition that (usually) doesn’t require raising an exception or terminating the program, warning messages are typically sent. Mostly, these warnings are descriptive of some underlying fault at work. But sometimes, they may not be required. This article will make you understand how to disable Python warnings in a very simple manner.
