How to Convert a List to a String in Python
3 Answers 3
By using ''.join
list1 = ['1', '2', '3'] str1 = ''.join(list1) Or if the list is of integers, convert the elements before joining them.
list1 = [1, 2, 3] str1 = ''.join(str(e) for e in list1)

I'd recommend to use: >>> " ".join([str(x) for x in L])

Since it wasn't specific in the question... If you want to preserve single string quotes on your list items (for sending a query to SQL, for instance), you can do something like this.
x = [1,2,3]y = "'" + "','".join(map(str, x)) + "'"Mar 5 '15 at 16:29

Anyone who is trying to re-use the string after converting the list to string can you this method: list1 = [1, 2, 3] str1 = ''.join('hello world' + str(e) + 'hello world' for e in list1) Output =========== hello world 1 hello world hello world 2 hello world hello world 3 hello world

@SenthilKumaran If the resulting string requires separate items such as when passing a list of files to a process, then "" has to be changed to " " (notice the space between the quotes). Otherwise, you end up with a contiguous string ("123" instead of "1 2 3"). This is OK if that was the intention, but needs to be mentioned in the response.

Just gonna point out that the second form works fine on almost any (single-depth) list.

I was looking for this here and found it elsewhere: If you want to have a newline for every list element (might be useful for long-string lists):
print ("\n".join(['I', 'would', 'expect', 'multiple', 'lines']))Mar 3 '18 at 11:55
The question may be a duplicate but the answer here is better than there. :) Plus this pops up as the top result on google unlike the other. (which I've noticed a lot with dupes)

Agree with @Bogdan. This answer creates a string in which the list elements are joined together with no whitespace or comma in between. You can use
', '.join(list1)to join the elements of the list with comma and whitespace or' '.join(to)to join with only white spaceSep 28 '18 at 6:32
