Nested lists and saving into a text file

Question

I have a nested list containing strings and integers that I'm trying to save into a txt file but I'm having trouble with formatting.

array = [(string1, int1),(string2, int2),(string3, int3),...(string_n, int_n)]
with open("output.txt", "w") as f:
    f.write(repr(array))

and get the array saved as is.

How do I format the output so that the format is as below instead of the array as is?

string1 int1
string2 int2
.
.
.
string_n int_n

This is propably a very newbie question, but I couldn't find anything similar with search...

Use the following:

array = [('s1', 1),('s2', 2)]

with open('out.txt', 'w') as f:
    for item in array:
        f.write('{} {}\n'.format(*item))

Output:

s1 1
s2 2
