existuje moznost ako zapisovat kompletny output do jedneho textaku? Kedysi som to robil tak, ze namiesto print som pouzival "print2(text,out=True/False)". Ak to inak nepojde, tak prerobim vsetky hlasky, ale keby sa dal niekde presmerovat výstup namiesto na displej do súboru, bolo by to fajn.

neviem, na akom systeme si, ale linuxovy syscall dup2 by to mohol vediet.

a to nefunguje len v C/C++?
lebo podla popisu pythonsky dup2() robi nieco ine.

robim to v linuxe a v podstate mi nic nebrani davat output cez pipe do txt suboru, ale bol by som rad, keby to riesil sam program.

Re[3]: output

nepoznam presny zapis, tak len schematicky:



logf = openfile("log.txt")  # otvorit log

os.dup2(logf.fd(), 1)       # presmerovat stdout -> logf

print "hello world"
