Answer 1

One can't join int's only strings. You can Explicitly cast to str all your data try something like this

for elem in lol:
    print (":".join(map(str, elem)))

or with generator

for elem in lol:
    print (":".join(str(i) for i in elem))

or You can use format instead of casting to string (this allows You to use complex formatting)

for elem in lol:
    print (":".join("'{}'".format(i) for i in elem))
