How to obtain a Thread id in Python?
threading.get_ident() works, or threading.current_thread().ident (or threading.currentThread().ident for Python < 2.6).
Using the logging module you can automatically add the current thread identifier in each log entry.Just use one of these LogRecord mapping keys in your logger format string:
%(thread)d : Thread ID (if available).
%(threadName)s : Thread name (if available).
and set up your default handler with it:
logging.basicConfig(format="%(threadName)s:%(message)s")
The thread.get_ident() function returns a long integer on Linux. It's not really a thread id.
I use this method to really get the thread id on Linux:
import ctypeslibc = ctypes.cdll.LoadLibrary('libc.so.6')# System dependent, see e.g. /usr/include/x86_64-linux-gnu/asm/unistd_64.hSYS_gettid = 186def getThreadId(): """Returns OS thread id - Specific to Linux""" return libc.syscall(SYS_gettid)
