It is useful mainly for system monitoring , profiling , limiting process resources and the management of running processes. It implements many functionalities offered by UNIX command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. Supported Python versions are 2. PyPy is also known to work. While psutil is free software and will always be, the project would benefit immensely from some funding. Keeping up with bug reports and maintenance has become hardly sustainable for me alone in terms of time.

Make python code continue after exception - Stack Overflow
The module pdb defines an interactive source code debugger for Python programs. It supports setting conditional breakpoints and single stepping at the source line level, inspection of stack frames, source code listing, and evaluation of arbitrary Python code in the context of any stack frame. It also supports post-mortem debugging and can be called under program control. The debugger is extensible — it is actually defined as the class Pdb. This is currently undocumented but easily understood by reading the source. The extension interface uses the modules bdb and cmd. Typical usage to run a program under control of the debugger is:.

Syntax for exception handling varies between programming languages , partly to cover semantic differences but largely to fit into each language's overall syntactic structure. Some languages do not call the relevant concept " exception handling "; others may not have direct facilities for it, but can still provide means to implement it. Most commonly, error handling uses a try Most assembly languages will have a macro instruction or an interrupt address available for the particular system to intercept events such as illegal op codes, program check, data errors, overflow, divide by zero, and other such.
The multiprocessing package offers both local and remote concurrency, effectively side-stepping the Global Interpreter Lock by using subprocesses instead of threads. Due to this, the multiprocessing module allows the programmer to fully leverage multiple processors on a given machine. It runs on both Unix and Windows. The multiprocessing module also introduces APIs which do not have analogs in the threading module.
