how to silence warnings

wxPython Users
1

hello, is there some way to silence deprecationwarnings in a wxpython app? for example those showing up in stdout from wx.lib.plot as

wx\lib\plot\utils.py:255: PendingDeprecationWarning: GetEnablePointLabel is pending deprecation. Please use self.enablePointLabel property instead.

but also originating by other libraries I use. I redirect stdout to a textctrl

I should silence warnings from python code, not from python.exe command line

I’ve found this on SO but doesn’t seem to work:

import warnings
warnings.filterwarnings("ignore")

I use win10, python 3.5-64, wxpython 4.0.1

thanks in advance for hints

Try this (“wrapping” the offending code part):

    # create your canvas
    panel = wxplot.PlotCanvas(self)
   
    import warnings
   
    with warnings.catch_warnings():
        warnings.filterwarnings('ignore', category=PendingDeprecationWarning)

        panel.GetEnablePointLabel()

``

You can “wrap” the whole app that way.

thank you, it works. I’ve changend

warnings.filterwarnings('ignore', category=PendingDeprecationWarning)

with

warnings.simplefilter('ignore')

to catch both deprecation warnings and pending deprecation warnings (and others)

I would like to wade in and point out that you should only turn off
deprecation, and other, warnings in release code, (not test or
development), and the real fix is to actually address the warnings.
Failure to address deprecation warnings will eventually result in a
sudden rush of errors (when the deprecated facility is removed) and
other warnings are normally a sign of something potentially going wrong.

In my experience suppressing warnings always bites you somewhere painful
sooner or later and usually at the worst moment in time. It certainly
has worked out that way for me.

I agree, this is my actual code

if main_is_frozen():
with warnings.catch_warnings():
warnings.simplefilter(‘ignore’)
run()
else:
run()
