Hi,
I need to sum values in two different list of different lengths.
List 1 (0,0,0)
+
List 2 (0,1)
I would like this result (0,1,0).
I try with managing lacing but any result!
I post an image to explain!!

Bonus points for an example of a while loop for the hell of it @Draxl_Andreas:

def matadd(a, b):
ret = []
c = 0
while True:
if c > len(a)-1 and c > len(b)-1:
break
elif c > len(a)-1:
z = b[c]
elif c > len(b)-1:
z = a[c]
else:
z = a[c] + b[c]
ret.append(z)
c += 1
return ret
OUT = map(matadd, IN[0], IN[1])

but a better python version in my opinion:

def tryadd(alist, ind):
try: return alist[ind]
except IndexError: return 0
def matadd(a, b):
ret = []
for i in range(max([len(a),len(b)])):
s = tryadd(a,i)
s += tryadd(b,i)
ret.append(s)
return ret
OUT = map(matadd, IN[0], IN[1])
