Session in GAE separated in comma's

sample i have a list:

sample = [a, b, c, d]

Then I want to pass the sample to the session:

self.session['sample'] = None #declaring the session...
for item in sample:
   self.session['sample'] = str(self.session['sample']) + "," + str(item)

But the output is:

None, a, b, c, d

I want the value of my session['sample'] would be = a, b, c, d

You could do it in one line instead of a loop with join() and list comprehension:

self.session['sample'] = ", ".join(str(item) for item in sample)

If you're happy doing it in a loop, you need to make the first item "" instead of None:

self.session['sample'] = "" # Empty string
for item in sample:
   self.session['sample'] += "," + str(item) # Note I've used += here

a += 1 is just a tidy way to write a = a + 1
