Get New List Based on Dictionary Key

[leoahum]

Here is my code. It gives me the wanted list, but the two "for" loops is a little redundant. I'm wondering if there is simpler way to code it out.

l = ['a','b','a','c','b']
D = {'a':[3,2],'b':[4,5],'c':[1]}


L = []

for i in range(len(l)):
    for k in D:
        if l[i] == k:
            L.append(D[k][0])
            D[k].remove(D[k][0])

Thanks!
