changing directory whist running python code -

-

this question has answer here:

i have piece of code runs 4 other pieces of code. when codes run write out put writes directory run code in. wondering if there way run code changes directory after every time, here code:

loop=np.arange(187761,187854) ext in loop:  ext=str(ext)  s0=''   dcom=["rm *.txt"]  dcom=s0.join(dcom)  nes=os.system(dcom)   a=sys.argv[1]  com=['cd /cygdrive/e/desar2.cosmology.illinois.edu+7443/desfiles/desardata/ops/red/', a,'/red/decam_00',ext, '/']  com=s0.join(com)  print com  sres=os.system(com)   com=['python /home/pythoncodes/other4.py ', '00'+ext]  com=s0.join(com)  print com  sres=os.system(com)   com=['python /home/pythoncodes/correctedmo.py ', '00'+ext]  com=s0.join(com)  print com  sres=os.system(com)   com=['python /home/pythoncodes/graphs.py ', '00'+ext]  com=s0.join(com)  print com  sres=os.system(com)   com=['python /home/pythoncodes/whiskerother4.py ', '00'+ext]  com=s0.join(com)  print com  sres=os.system(com)

i hoping top part change directory every ext, doesn't. there way or should alter programs write different directories?

you can use os.chdir(path) change current directory.

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
