C:\Users\Terry>py -2 -m idlelib.idle -c "print True" >>> *** Error in script or command! Traceback (most recent call last): File "<pyshell#0>", line 1 print True ^ SyntaxError: invalid syntax https://stackoverflow.com/questions/30280525/python-idle-give-a-false-syntax-error In answer, phihag points out that PyShell.py has future import and compiles with code = compile(source, filename, "exec") The fix is to add dont_inherit=True.

New changeset cebd51686565 by Terry Jan Reedy in branch '2.7': Issue #24222: Fix regression introduced with idlelib/PyShell.py future print https://hg.python.org/cpython/rev/cebd51686565

I added "from __future__ import print_function" to 2.7 PyShell when I backported the bugfix of #22420. The use of print rather than write is part of the fix as print is more fault tolerant.

This trivial patch fixes a regression I introduced in 2.7.9. It would be nice if you could pull it into the .10 release. (I would not ask if it were not a recent regression.)
