我正在制定此计划,根据客户购买的数量提供折扣。
方向如下: 某些在线商店根据购买总额给出折扣:
If the purchase total is over $50, a 5% discount is applied
If the purchase total is over $100, a 10% discount is applied
If the purchase total is over $500, a 15% discount is applied
在应用任何折扣后,使用if-elif-else链计算购买金额。对于您的演示,请购买$ 499.99。
这就是我到目前为止创建的内容,但它似乎没有正常运行,我想知道如何才能使我的代码更好,也许我正在使用if-elif-else代码。提前谢谢大家。
if total_cost>=10:
if give_shopper_5percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True
elif total_cost>100:
if give_shopper_10percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True
else total_cost>=500:
if give_shopper_15percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True

根据您的描述,第一个total_cost
限制是错误的。你不应该在total_cost >= 500
试试这个:
total_cost = int(input('Please enter a total_cost:'))
if total_cost>=500:
print"You have won a discount by 15 percent"
total_cost *= 0.85
elif total_cost>100:
print"You have won a discount by 10 percent"
total_cost *= 0.9
elif total_cost>=50:
print"You have won a discount by 5 percent"
total_cost *= 0.95
else:
print 'you total cost is not in the range of discount!'
print 'Now the total cost is ', total_cost

您必须先检查最大折扣,否则您可以按预期给予更多折扣; - )
if total_cost>=500:
...
elif total_cost>=100:
...
elif total_cost>=10:
...
else:
pass

你的缩进是不合时宜的。在python中很重要。 (试试这个?)
if give_shopper_5percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True
elif total_cost>100:
if give_shopper_10percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True
else total_cost>=500:
if give_shopper_15percent_discount():
print"You have won a discount"
total_cost -= discount
candidate_prime =True
也适用于折扣尝试倍增而不是减去。
