C API -- Two questions

Hi Everyone, I am writing a C extension and encountered two problems. 1) How can I include a description of the arguments? I can include a description string. No problem. But whenever I say help(my_func) it shows the arguments are "... ". However, if a function is defined in python, I will defini

Re: two questions about thread

The best way to do this is by using a flag or event that the child-threads monitor each loop (or multiple times per loop if it's a long loop). If the flag is set, they exit themselves. The parent thread only has to set the flag to cause the children to die. Kevin. "Bryan Olson" <[EMAIL PROTECT

two questions about thread

hi there, I'm new to python, and have two questions: a. how to exit the whole process in a thread? b. when thread doing a infinite loops, how to terminate the process?: it seems that the follow doesn't work, in my Windows XP: thread.start() thread.join(

Re: Two questions on PyDev for Eclipse

Hi, for 2: as far as I know, eclipse must have 'local', or at least 'emulated' local access, so, if you have samba access, it should do what you want. for 1... I use it a LOT without any problems for some really big projects ( with about 2.000 python modules -- not counting the python install

Two questions on PyDev for Eclipse

The first is general; what are users' experience with PyDev for Eclipse. It looks pretty good to me right now, but I've only started playing with it. Converting to Eclipse is a major effort, and if there are problems which would prevent pydev from being useful right now, I'd certainly appre

Two questions on lambda:

Hi, I cannot find the way to do generic lambda functions using the lambda syntax in python. I am probably missing a point. For example, the code # f = lambda : print "hello" # f() does not compile, although: # def f(): # print "hello" # f() does compile. Is there a particular syntax fo
