一日一技：使用装饰器简化大量if判断（二）
"大量计算代码" discount = 0.1 return discount 如果要定义不等于逻辑，就在.register()中添加一个参数op： @get_discount.register ，所以可以看到get_discount(6)和get_discount(10)返回的都是1. discount @get_discount.register(10, op='gt') def parse_level_gt2(level): discount = 100 return <5') discount = 0.5 return discount 如果区间存在全包含、部分包含应该运行哪个函数？ 例如： @get_discount.register(ge=2, lt=00) ... @get_discount.register(ge=20, lt=50) ...
