Serhiy Storchaka added the comment:
The equivalent of used "tr" command is .upper(), not .swapcase().
Instead of the loop
for s in sys.stdin.read(): sys.stdout.write(s.upper())
you can write just
sys.stdout.write(sys.stdin.read().upper())
But actually the loop is needed for testing purpose.
while True:
b = sys.stdin.buffer.read(1)
if not b:
break
sys.stdout.buffer.write(b.upper())
And sys.executable should be escaped for the case of spaces or other special
symbols in the path.
All this complicates tests too much. I prefer to skip some tests on Android.
