Hi all
I have often read that the quickest way to concatenate a number of strings
is to place them in a list and 'join' them -
C:\Users\User>python -m timeit -s "x='a'*500; y='b'*500; z='c'*500"
''.join([x, y, z])
50 loops, best of 5: 307 nsec per loop

Try something like this:
```
import sys
def replace(lineno, replacement):
for i, line in enumerate(sys.stdin.readlines()):
if i == lineno:
line = replacement
print(line.strip())
replace(2, "REPLACEMENT")
```
