SyntaxError: multiple statements found while compiling a single statement

Any idea how to correct this error ? Looks fine to me ....

>>> rect_x = 50
 
# -------- Main Program Loop -----------
while not done:
    for event in pygame.event.get(): # User did something
        if event.type == pygame.QUIT: # If user clicked close
            done = True # Flag that we are done so we exit this loop
