Copy-paste into Python interactive interpreter and indentation

Question

This piece of code, file test.py,

if 1:
   print \"foo\"
print \"bar\"

can be successfully executed with execfile(\"test.py\

Answer 1

Continuation lines are needed when entering a multi-line construct. --Interactive mode, The Python Tutorial (v2) (v3)

So you need to enter:

if 1:
   print "foo"

print "bar"

I've yet to find a suitable explanation as to why it's different to a non-interactive session, alas.
