An (obvious) alternative is to construct the desired output as one string, 
then print it. If the desired output is
a,b,c,d,e,f,g,h,i, you could:

out = ''
for x in range(1,len(mystr)):
      out += "%s," % mystr[x]
print out

Since mystr is a sequence this simplifies to:

out = ''
for x in mystr:
      out += "%s," % x
print out

Even simpler:

print ','.join(mystr) + ','
