Multiply list in list string items with list in list integers

Question

I have 2 lists: list1 and list2

list1 is a list in list and contains various strings list2 is also a list in list and consists of different integer values

the dimensions of both lists is the same

how do I multiply each string in list1 with each integer in list2 in order to achieve something like that:

list1 = [['ABC','DEF'],['GHI','JKL'],['MNO','PQR']]
list2 = [[2, 2], [3, 3], [4, 4]]


result = [['ABC', 'ABC', 'DEF', 'DEF'], ['GHI', 'GHI', 'GHI', 'JKL', 'JKL', 'JKL'], ...]

Thank you very much

I already tried the zip() function and worked with the * operator but nothing worked

Answer 1

Expecting that sublists in list2 can have varying values. I coded this:

list1 = [['ABC','DEF'],['GHI','JKL'],['MNO','PQR']]
list2 = [[2, 2], [3, 3], [4, 4], [1, 1]]

combined = []
for sublist1, sublist2 in zip(list1, list2):
    sublist = []
    for elem1, elem2 in zip(sublist1, sublist2):
        sublist.extend([elem1]* elem2)

    combined.append(sublist)

print(combined)

Result:

[['ABC', 'ABC', 'DEF', 'DEF'], ['GHI', 'GHI', 'GHI', 'JKL', 'JKL', 'JKL'], ['MNO', 'MNO', 'MNO', 'MNO', 'PQR', 'PQR', 'PQR', 'PQR']]
