Summary:
Noticed in the original, failed CI run of #4507 that this script ran in
Python 2, since its
print()caused an extra()to be printed (sincewe turned off
print_functionin #4503). This happens because itsshebang specifies the system’s default
pythonand the CI job thatinvokes it doesn’t set up a Python 3 virtualenv. The script still works,
since it’s effectively bicompatible, but for consistency we should still
make sure that everything runs on Python 3 only (else the tasks in #4488
are not necessarily sound).
Test Plan:
git grep bin/pythononly matches this line, and we have no uses of/usr/bin/env python, either.wchargin-branch: py3-whitespace-test
