Combine lists inside of lists python

Question

I am looking for a way to turn this:
[['a','b'],['c','d'],['e','f']]
Into this:
'ab\ncd\nef'
So that when it is printed out it will look like:

ab
cd
ef

"\n".join("".join(s) for s in [['a','b'],['c','d'],['e','f']]) — Dimitris Fasarakis Hilliard

Try:

list_ = [['a','b'],['c','d'],['e','f']]
'\n'.join([''.join(l) for l in list_])

Regarding your comment (which seems now deleted): If you want the elements in the sublist be seperated by comma, just replace ''.join(l) by ','.join(l)

Here you go for a harder way :

x = [['a','b'],['c','d'],['e','f']]
string = ''
for i in x:
    for e in i:
        string+=e
    string+="\n"

print string

however, "\n".join() also works
