Thank Tim, Raymond, and all.
In my test, Tim's t1 was fastest and Raymond's triple3 is very near to Tim's
t1.
Anyway both of them took only 6~7% time of my original .extend() version.
I think that following n_ple() is a good generalized function that was 1~3%
slower than t1() and triple3() for "t

Hi, all.
I want to improve speed of following simple function.
Any suggestion?

def triple(inputlist):
results = []
for x in inputlist:
results.extend([x,x,x])
return results
