Python Deprecated Error
Contents |
This module never needs to be imported explicitly: the exceptions are provided in the built-in namespace python filenotfounderror as well as the exceptions module. For class exceptions, python custom exception in a try statement with an except clause that mentions a particular class, python exception message that clause also handles any exception classes derived from that class (but not exception classes from which it is derived). Two exception classes that are

not related via subclassing are never equivalent, even if they have the same name. The built-in exceptions listed below can be generated by the interpreter or built-in functions. Except where mentioned, they have an "associated value" indicating the detailed cause of the error. This may be a string or a tuple python exception class methods containing several items of information (e.g., an error code and a string explaining the code). The associated value is the second argument to the raise statement. If the exception class is derived from the standard root class BaseException, the associated value is present as the exception instance's args attribute. User code can raise built-in exceptions. This can be used to test an exception handler or to report an error condition "just like" the situation in which the interpreter raises the same exception; but beware that there is nothing to prevent user code from raising an inappropriate error. The built-in exception classes can be subclassed to define new exceptions; programmers are encouraged to derive new exceptions from the Exception class or one of its subclasses, and not from BaseException. More information on defining exceptions is available in the Python Tutorial under User-defined Exceptions. The follo

I can't not http://stackoverflow.com/questions/879173/how-to-ignore-deprecation-warnings-in-python use MySQLdb and I can't modify it either. –Edward Falk Dec 20 '10 at 17:43 7 @PaoloBergantino, your comment did make me laugh, but given that there are (or have been) actually things in the standard Python distribution that raise DeprecationWarning it's not a complete solution. –poolie Nov 7 '11 at 5:13 add a comment| 7 Answers 7 active oldest votes up vote 71 down vote accepted I Googled and found: #!/usr/bin/env python -W ignore::DeprecationWarning If you're on Windows: pass -W ignore::DeprecationWarning as an argument to Python. (But resolving the issue may be a better course of action... casting to int is not hard.) Edit: user shahensha pointed out that the link this answer original pointed to was broken. Changed the link to just point to the documentation. Note that as for version 2.7 and 3.2 deprecation warnings are ignored by default. share|improve this answer edited Mar 14 '15 at 9:27 answered May 18 '09 at 18:50 Stephan202 37.1k689119 casting works too .. but the flag was helpful ! –Mohammed May 18 '09 at 19:07 6 I wish I could make this work... I get a /usr/bin/env: python -W ignore::DeprecationWarning: No such file or directory error. It works if I run python with the -W ignore::DeprecationWarning option on the command-line, but /usr/bin/env doesn't deal with it. –weronika Oct 4 '11 at 18:34 2 Seems to be a windows-only solution. –Daniel Miles Dec 16 '11 a

Background In the newer versions of Python (from 2.6) we are supposed to inherit our custom exception classes from Exception which (starting from Python 2.5) inherits from BaseException. The background is described in detail in PEP352. class BaseException(object): """Superclass representing the base of the exception hierarchy. Provides an 'args' attribute that contains all arguments passed to the constructor. Suggested practice, though, is that only a single string argument be
