这个不对？输入显示：IndentationError: expected an indented block？？ 还有如果不输入【list】这个括号就是错误而无序的吗
months = set(["Feb","Jau","Mar","Apr","May"]) x = "monday" if x in months: print "x: ok" else: print "x:error"
months = set(["Feb","Jau","Mar","Apr","May"]) x = "monday" if x in months: print "x: ok" else: print "x:error"
