Need help with List of Lists

[Larz60+]

Sure,just use a separate index:

list_a = [-1, 2, -2, 3, 41, 38, 22, 10, -1, 3]
list_b = [40, 30, 20, 10]
 
e_len = len(list_a) - len(list_b) + 1
 
for a_idx in range(e_len):
    elist = []
    b_idx = 0
    for bval in list_b:
        elist.append(list_a[a_idx + b_idx]*bval)
        b_idx += 1
    print(elist)
