python - If、Elif 和 Else 在利润计算器应用程序中未显示正确的打印值

标签 python

我是 StackOverflow 的新人，但从 8 岁起我就一直在“摆弄”HTML 和 CSS。我最近选修了一门 Python 类(class)(25 岁时)，并决定使用编程作为扩展我的职业道路。我正在开发一个小程序，允许我和其他 Shopify 电子商务所有者(在我目前居住的巴西)使用用户输入(产品零售价、产品成本、每次转化费用)来计算单个产品的利润率。它还应该显示利润率，具体取决于商店/供应商为产品提供无息融资(包裹)的次数。存在某种问题，程序仅显示一次性付款的利润率。我已经研究了几个小时并尝试谷歌搜索，但似乎找不到与我的问题相关的具体问题。我的最后一招是在我完全发疯之前向你们寻求帮助。该程序以葡萄牙语显示，但所有变量均以英语分配。如果您需要任何帮助来理解代码，请告诉我!我已尽力使其尽可能易于理解。

最佳答案

类似的语句

elif parcelas == 15 or 18 or 17:

不会工作。您需要执行以下操作:

elif parcelas == 15 or parcelas == 18 or parcelas == 17:
