formatting list -> comma separated

[Robert]

given d:

d = ["soep", "reeds", "ook"]

I want it to print like

soep, reeds, ook

I've come up with :

print ("%s"+", %s"*(len(d)-1)) % tuple(d)

but this fails for d = []

any (pythonic) options for this?

[Jerry Hill]

given d:
d = ["soep", "reeds", "ook"]

I want it to print like
soep, reeds, ook

use the join() method of strings, like this:

d = ["soep", "reeds", "ook"]
', '.join(d) 'soep, reeds, ook'
d = []
', '.join(d) ''

================================
the old fashion way would be:

d = ["soep", "reeds", "ook"]
if len(d) > 0:
print ("%s"+", %s"*(len(d)-1)) % tuple(d)

# if d= [] then print stmnt bypassed
