Re: [Help-bash] Using <<-'EOF' with python

[Peng Yu]

This is strange. After I change the TABs to spaces, main.sh indeed works.

But python should be able to accept TABs as shown the following
example. So why TABs can not be used in `python <<-EOF`?

~$ cat -T < main1.py
# vim: set noexpandtab tabstop=2 shiftwidth=2 softtabstop=-1 fileencoding=utf-8:

for i in xrange(3):
^Iprint i
~$ python < main1.py
0
1
2
