arraylist - Python: concatenate 2 list -

-

i have 2 lists in python:

list1 [1,1,0,0,1,1,0,0,1,1]  list2 [a,b,c,d,e,f,-,-,-,-]

i output follow:

output

[a,b,-,-,c,d,-,-,e,f]

i lost, tried multiple things without luck. have idea how it? here's try:

for e in range (0, len(stringas)):   if controllo[e] == "1":     memoria.append(stringas[e])   if controllo[e] == "0":     memoria.append("-")     blocco.append(e)     salva.append(stringas[e])  print (stringas) print (memoria)   f in salva:   print (blocco[c])   print (salva[c])   memoria.insert(blocco[c], salva[c])   c = c + 1

thank in advance.

try this:

output = [list2.pop(b-1) b in list1]
