Python MemoryError when appending a list -

i've small python (2.7.10) script, can see below.

def numbers_calc(max_num, num_step):     """returns every number 0 max_num num_step step."""     n = 0     l = []      while n < max_num + 1:         l.append(n)         n += n * num_step      return l  n_l = [] n_l.append(numbers_calc(25, 1))  print "here numbers." print n_l 

the function numbers_calc meant take given args, form list, , populate numbers (with num_step step when calculating) before reaches max_num + 1. script return it's local list named l.

however, every time run script, encounter memoryerror. here's python returned when ran script:

traceback (most recent call last): file "num.py", line 13, in <module>     n_l.append(numbers_calc(25, 1))   file "ex33.py", line 7, in numbers_calc     l.extend(i) memoryerror 

i tried looking up, saw nothing helpful. hope can me!

the issue in line -

n += n * num_step 

here, initialized n 0 , , multiplying n , num_step , result 0 , , adding n . n stays @ 0 . if try loop 0 max_num+1 every num_step, should use range() function, example -

def numbers_calc(max_num, num_step):     """returns every number 0 max_num num_step step."""     l = []      in range(0,max_num + 1,num_step):         l.append(i)      return l
