How to disable Python warnings?
Look at the Temporarily Suppressing Warnings section of the Python docs:
If you are using code that you know will raise a warning, such as a deprecated function, but do not want to see the warning, then it is possible to suppress the warning using the
catch_warnings
context manager:
import warningsdef fxn(): warnings.warn("deprecated", DeprecationWarning)with warnings.catch_warnings(): warnings.simplefilter("ignore") fxn()
I don't condone it, but you could just suppress all warnings with this:
import warningswarnings.filterwarnings("ignore")
Ex:
>>> import warnings>>> def f():... print('before')... warnings.warn('you are warned!')... print('after')...>>> f()before<stdin>:3: UserWarning: you are warned!after>>> warnings.filterwarnings("ignore")>>> f()beforeafter
You can also define an environment variable (new feature in 2010 - i.e. python 2.7)
export PYTHONWARNINGS="ignore"
Test like this: Default
$ export PYTHONWARNINGS="default"$ python>>> import warnings>>> warnings.warn('my warning')__main__:1: UserWarning: my warning>>>
Ignore warnings
$ export PYTHONWARNINGS="ignore"$ python>>> import warnings>>> warnings.warn('my warning')>>>
For deprecation warnings have a look at how-to-ignore-deprecation-warnings-in-python

From documentation of the warnings
module:
#!/usr/bin/env python -W ignore::DeprecationWarning
If you're on Windows: pass -W ignore::DeprecationWarning
as an argument to Python. Better though to resolve the issue, by casting to int.
(Note that in Python 3.2, deprecation warnings are ignored by default.)
Or:
import warningswith warnings.catch_warnings(): warnings.filterwarnings("ignore", category=DeprecationWarning) import md5, shayourcode()
Now you still get all the other DeprecationWarning
s, but not the ones caused by:
import md5, sha
