Exposing some Python classes without coupling to file structure -


my project consists of several python classes, split several files.

projname/     a.py # has classes a1 , a2     b.py # has classes b1 b2 b3     c.py # has class c test/ doc/ bin/

i'd able make (or all) of classes public, that, either bin dir, or python script, can like:

import projname ... myvar = projname.a1()

i can't figure out how that. best can far is:

import projname.a import projname.b import projname.c  myvar = projname.a.a1()

i don't 2 reasons:

  1. i don't want clients of code have know , care files used distribute classes. don't want break clients if change files
  2. i'd prefer expose classes outside project - not of them

put __init__.py projname/ following content:

from .a import a1, a2 .b import b1, b2, b3 .c import c

this turns projname package namespace contains whatever __init__.py contains, in case a1, a2, b1, b2, b3 , c.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...
