Untested, but it's a hack I've used in a few places. The if tells
Python to expect an indent, and nobody cares if your first indent is
two miles and the one after that is only another two spaces.

Thanks. Nice!

You can use bash here document feature, <<-, that strips heading tab
characters but not spaces.


#!/bin/bash

for i in 1 2 3 4; do
python /dev/stdin <<-EOF
for i in range($i):
print i # two tabs and four spaces
EOF
done

Or alternatively you can use a temporary file:


#!/bin/bash

TEMPFILE=$(mktemp)
trap 'rm -f $TEMPFILE' TERM INT

cat > $TEMPFILE <<EOF
import sys

for i in range(int(sys.argv[1])):
print i
EOF

for i in 1 2 3 4; do
python $TEMPFILE $i
done
