python - What does this code mean: "print >> sys.stderr"

Question

print >> sys.stderr, "Error in atexit._run_exitfuncs:"

Why print '>>' in front of sys.stderr?

Thanks.

Answer 1

This syntax means writes to a file object (sys.stderr in this case) instead of standard output. [Link]

In Python 3.0, print becomes a function instead of a statement: [Link]

print("Error in atexit._run_exitfuncs:", file=sys.stderr)
