printing list

[compboy]

How do you print elements of the list in one line?

alist = [1, 2, 5, 10, 15]

so it will be like this:
1, 2, 5, 10, 15

because if I use this code

for i in alist:
print i

the result would be like this

1
2
5
10
15

Thanks.

Well, first, if you just print alist you'll get

[1, 2, 5, 10, 15]

which may be good enough. If that's not what you want then you can suppress the automatic RETURN that follows a print's output by adding a trailing comma to the print statement, like this

for i in alist:
print i,

1 2 5 10 15

There are a number of ways to do it but if you want a one-liner:

print repr(alist)[1:-1]

will meet your spec.

Or one of:

print ', '.join(str(x) for x in a)

print ', '.join(map(str, a))

both of which work if the list contains non-integer elements.
