How can I output integers only?

Question

Here is my code

list = [1,2,3]
for i in list:
    print(i)

This is the output

1
2
3

What I'm looking for

1, 2, 3

Answer 1

If python 3 print(i, end =", ")

If python 2 append a comma to the print to escape the newline print(i),

Answer 2

A mixture of generators and join

lst = [1,2,3]
print(','.join(str(i) for i in lst))
