This is called hexversion since it only really looks meaningful when viewed as the result of passing it to the built-in hex() function.

However, I added the calls to join because I expect that you will need, at some point in the future, to know how to wait for a thread to complete its weblink I don't know the implications of this as I have only just started using flask. sys.gettrace()¶ Get the trace function as set by settrace(). Unhandled Exceptions¶ Many applications are structured with a main loop that wraps execution in a global exception handler to trap errors not handled at a lower level.
Setting it to a value <= 0 checks every virtual instruction, maximizing responsiveness as well as overhead. The return value of exc_info() is a three member tuple containing the exception class, an exception instance, and a traceback. Basically, while Python is shutting itself down, it attempts to close stdout, but that fails because there is still buffered output waiting to be read. navigate here Its behavior is part of the implementation platform, rather than part of the language definition, and thus may not be available in all Python implementations. sys.settscdump(on_flag)¶ Activate dumping of VM
The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. When set to 0 or less, all traceback information is suppressed and only the exception type and value are printed. L.

- The function is thread-specific, but there is no way for the profiler to know about context switches between threads, so it does not make sense to use this in the presence
Do not extract version information out of it, rather, use version_info and the functions provided by the platform module.
