for elem in lol:
      print (\         


        

Answer 1

Use a list comprehension and str.join:

Convert the integers to string(using str()) before joining them

>>> lis = [[1,2],[3,4],[5,6],['five','six']]
>>> print ("\n".join([ ":".join(map(str,x))   for x in lis]))
1:2
3:4
5:6
five:six

or:

>>> print ("\n".join([ ":".join([str(y) for y in x])   for x in lis]))
1:2
3:4
5:6
five:six
