Can't get sys.stdin.readlines() to work

[tin...@isbd.co.uk]

I'm trying to read some data from standard input, what I'm actually
trying to do is process some date pasted in using the mouse cut and
paste on a Linux box (xubuntu 9.10) in a terminal window.

First attempts failed so I'm now trying the trivial:-

import sys
data = sys.stdin.readlines()
print "Counted", len(data), "lines."

When I run this and try to paste something into the terminal window I
get the following errors:-

/home/chris/bin/m2r.py: line 2: syntax error near unexpected token `('
/home/chris/bin/m2r.py: line 2: `data = sys.stdin.readlines()'

It does exactly the same if I try:-

cat | m2r.py

and then paste something into the window.

So - what on earth am I doing wrong?

You haven't put a shebang line at the top.

#!/usr/bin/env python

import sys
data = sys.stdin.readlines()

...

Trying to run Python scripts with /bin/sh, probably.

First of all, does you PATH include the current directory (.)? It looks
like it does, because your computer seems to be trying to execute the
m2r.py script. However, because that script does not start with a
"shebang" line - the one you need is probably either

#!/usr/bin/python

or

#!/usr/bin/env python

the shell is trying to run the script using the wrong interpreter.

Yup. I can't count the number of times I've run ImageMagick's
"import" program unintentionally...
