How can I format a list to print each element on a separate line in python?

Question

How can I format a list to print each element on a separate line? For example I have:

mylist = ['10', '12', '14']

and I wish to format the list so it prints like this:

10
12
14

so the \n, brackets, commas and '' is removed and each element is printed on a separate line Thanks

Solution 1

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

Solution 2

Use str.join:

In [27]: mylist = ['10', '12', '14']

In [28]: print '\n'.join(mylist)
10
12
14

This would actually work better than str.join which expects each element to be a str.

As inspectorG4dget said, this require every element to be str. A simple workaround would be print '\n'.join(map(str, myList)).

@inspectorG4dget Thank to notice, see my comment below for a workaround using str.join even without all elements being str.

this should be accepted as correct answer, it is far better than doing a loop

@SergeyAntopolskiy I wonder if doing a loop is actually that bad. The loop just reads the values and outputs them. Whereas the join results in the creation of a new string in the memory containing all the values and then prints it out. That could result in a performance penalty for long lists IMO.

@JigarMehta you may have a point there. at least, this should be accepted as a correct answer, if not the correct answer
