how to iterate through a nested list element by element to create a different string each time

Question

I’m doing some practice problems and I’m trying to figure out how to go through nested lists so that it does this:

example list: [['a','b','c'],['d','e','f'],['g','h','j']]
expected: ['a','ab','abc','b','bc','c']

and it does this for each list
what I’ve tried doing so far:

    idk = ""
    for i in range(len(example_list)):
        idk.join(example_list[i][i:i+1])

im confused on to go one by one when ive tried other ways i just get a huge string

Answer 1

words=[]    
for i in list:
    for j in range(len(i)):
        k=j;
        temp=""
        while k<len(i):
            temp+=i[k]
            words.append(temp)

I think this is what you are looking for
