python - anyone know why this doesn't work? --> [cp_props[x]][1] -


this piece of code doesn't work, , "indexerror: list index out of range" error, not sure why, know why doesn't work? thanks.

 print([cp_props[x]][1])

it should name of item in list, name of anothert list , open 2nd element in list???

okay, works this:

 globals()[cp_props[x]][1]

but there other more simple way of doing it? thank you.

[cp_props[x]] one-element list. 1 , element cp_props[x], whatever is. element number 0. there no element number 1, that's why selection expression [1] fails.

expression globals()[cp_props[x]][1] has totally different meaning. reading left right:

  1. globals() list of global variables.
  2. globals()[cp_props[x]] selection list - is, global variable.
  3. globals()[cp_props[x]][1] second element of that global variable.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
