Python How to print list of list

Question

I want to print list of list in python 3.x with below code, but it is giving an error.

lol=[[1,2],[3,4],[5,6],[\'five\',\'six\']]
for elem in lol:
      print (\         


        

Answer 1

I'd go for:

for items in your_list:
    print (*items, sep=':')

This takes advantage of print as a function and doesn't require joins or explicit string conversion.

Answer 2

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

Answer 3

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))
