python - How to print this pattern using Tuples? -


i new python tuples, , doing learning exercise on same. how should print following pattern when input string hi,hello,welcome.

(('hi', 'hello', 'welcome'),)  ((('hi', 'hello', 'welcome'),),)  (((('hi', 'hello', 'welcome'),),),)

my attempt

n = input() arr = tuple(raw_input().split()) arr1 = list() print arr while(n>0) :     print(tuple(arr,))     n -= 1

just define (or create) tuple @ start, nest on (reusing same variable):

n = 3 arr = ('hi','hello','welcome')  # or tuple(raw_input().split())  while(n>0):     arr = (arr,)  # that's enough create tuple inside tuple     print(arr)     n -= 1

result:

(('hi', 'hello', 'welcome'),) ((('hi', 'hello', 'welcome'),),) (((('hi', 'hello', 'welcome'),),),)

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...
