Fredrik Carlsen Software Engineer at Yahoo! [email protected] Infinite Lists Python Published 06 Jul 2014 When you need to solve a problem and use lists of unknown size, you should use generators to not waste memory. You can easily make use of generators to create infinite lists in Python. def inf_list ( start = 0 ): x = start while True : x += 1 yield x #Never ending loop for x in inf_list (): print x "prints 0, 1, 2 ..." #More examples using custom operaotrs from operator import add , sub #Using add operator, increasing list def inf_list ( x = 0 , op = add ): while True : yield x x = op ( x , 1 ) #Never ending loop.. for x in inf_list (): print x "prints 0, 1, 2 ..." #Using sub operator, decreaseing list def inf_list ( x = 0 , op = sub ): while True : yield x x = op ( x , 1 ) #Never ending loop.. for x in inf_list (): print x "prints 0, -1, -2..." When and how to use this? Say you want the first 1000 numbers divisible by 3, but you don’t know how large the list needs to be. def |
