The trick to threads is to create a subclass of threading.Thread, define
the 'run' function and call the 'start()' method. I find threading quite
generally useful so I created this simple generic function for running
things in threads...
Great idea. Thanks for posting this.
def run_in_thread( func, func_args=[], callback=None, callback_args=[] ):
import threading
class MyThread ( threading.Thread ):
def run ( self ):
# Call function
if function_args:
result = function(*function_args)
else:
result = function()
The check is not necessary. by design, f(*[]) == f()
Names do not match param names ;=)
# Call callback
if callback:
if callback_args:
callback(result, *callback_args)
else:
callback(result)
Ditto. g(x,*[]) == g(x)
def run(self):
result = func(*func_args) # matching run_in_thread param names
callback(result, *callback_args)
MyThread().start()
This is one of the best uses I have seen for a nested class definition.
Suggestions from hardcore pythonistas on how to my make run_in_thread
function more elegant are quite welcome also :)
I shortened it, at least.
