Print Delimited list

Question

Here is a Python code for printing a list of comma separated values:

for element in list:
    print element + ",",
 

What is the preferred method for printing such that a comma does not appear if element is the final element in the list.

For example

a = [1, 2, 3]
for element in a
  print str(element) +",",

output
1,2,3,
desired
1,2,3

Answer 1

You can try the following and see if it works :

>>> ','.join(map(str,a))
'1,2,3'
