To disable Python warnings, we can call the warning.catch_warnings method.

For instance, we write

import warnings

def f():
    warnings.warn("deprecated", DeprecationWarning)

with warnings.catch_warnings():
    warnings.simplefilter("ignore")
    f()

to call warnings.catch_warnings to catch warnings.

In the f function, we raised a warning with warnings.warn.

In the with block, we call warnings.simplefilter with 'ignore' to temporarily ignore warnings in the block.
