I do not understand how that code works ?
Where and why and how should I use this.
def _ignore_warning(function):
@functools.wraps(function)
def __ignore_warning(*args, **kwargs):
# Execute the code while catching all warnings
with warnings.catch_warnings(record=True) as ws:
# Catch all the warnings of the given type
warnings.simplefilter('always', warning)
# Execute the function
result = function(*args, **kwargs)
# re-warn all warning beyond the expected count
if count is not None:
for w in ws[count:]:
warnings.warn(w.message)
return result
return __ignore_warning
return _ignore_warning
@ignore_warning(DeprecationWarning, count=1)
def spam():
warnings.warn('deprecation 1', DeprecationWarning)
warnings.warn('deprecation 2', DeprecationWarning)
with warnings.catch_warnings(record=True) as ws:
spam()
for i, w in enumerate(ws):
print(w.message)
