Convert list of lists of numbers into a list of lists with the numbers separated by commas

I have a list of lists like the following one:

list = [[226], [44], [8]]

I'd like to convert this list of lists into a list of lists where the numbers are separated by commas. Something like this:

[[2,2,6], [4,4], [8]]

I have been trying to do this using the split function. I didn't find a duplicate for this question.

You can do something like this. This will work even if you have multiple elements in each sublist like [[226,542], [44], [8]]

def list_of_list(list):
result = []
for l in list:
    for item in l:
        sub_list= []
        for c in str(item):
            sub_list.append(int(c))
        result.append(sub_list)
return result

print(list_of_list([[226], [44], [8]]))

Output:

[[2, 2, 6], [4, 4], [8]]

This will work:

foo = [[226], [44], [8]]
foo = [eval('[' + ','.join(str(i[0])) + ']') for i in foo]

Or this will work:

foo = [[226], [44], [8]]
foo = [[int(n) for n in str(i[0])] for i in foo]

You can create something simple like this:

foo = [ 'a', 'b', 'c' ] print ",".join(foo) a,b,c

Hope this helps
