I have this list (asList) It is read from a file and now i need do separate it by the colons and to create new list of lists

```
asList =  ['green:g----:g::g\n', '\n', 'green:gr---:r::gr\n', '\n', 'green:gree-:e::gre\n', '\n', 'green:green:n::gren\n', '\n']

```

after this for loop

```
for i in asList:
    print i.split(":")

```

the result is this:

```
['green', 'g----', 'g', '', 'g\n']
['green', 'gr---', 'r', '', 'gr\n']
['green', 'gree-', 'e', '', 'gre\n']
['green', 'green', 'n', '', 'gren\n']

```

and now i need to combine these 4 lists into one single list of lists with 4 elements (each list to be one element) but i don't have any idea of how to do it. Please can someone help me here? Thank you
