python - Why does return not return my Variable? -


my problem quite easy think...

i need go through excel list , want print out fields (to begin first 10 rows (so low_run = 0, high_run=10, , run=10 too).

now wanna next 10 need:

def get_input(high_run, low_run, run):     pressed_key = input('')      if pressed_key == "n":  # next page         set_high_run_np(high_run, run)         set_low_run_np(low_run, run)  def set_high_run_np(high_run, run):     if high_run != len(ldata):         high_run = high_run + run      return high_run  def set_low_run_np(low_run, run):     if low_run != len(ldata) - run:         low_run = low_run + run      return low_run

the functions work , put out low_run = 10 , high_run = 20. won't return numbers can used... idea why?

thanks in advance , sorry grammar mistakes. no native speaker

cya!

i think miss return in first function

def get_input(high_run, low_run, run):     pressed_key = input('')      if pressed_key == "n":  # next page         return set_high_run_np(high_run, run), set_low_run_np(low_run, run)  def set_high_run_np(high_run, run):     if high_run != len(ldata):         high_run = high_run + run      return high_run  def set_low_run_np(low_run, run):     if low_run != len(ldata) - run:         low_run = low_run + run      return low_run

i added return. chose return tuple of values in python done comma. there lot of other ways can choose return values, need return them.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
