Yes.  This could even be made a syntax error, as with other contextual

>>> continue
SyntaxError: 'continue' not properly in loop
>>> break
SyntaxError: 'break' outside loop
# these messages should be same

>>> return 0
SyntaxError: 'return' outside function

# so why not " 'global' outside function"

No.  This can serve as documentation and/or preparation/protection for
