哦,孩子,你的代码离工作还很远

不能使用相同的名称定义函数和变量;距离和时间是函数,因为您稍后定义了它们

改为使用小写变量名,从函数返回结果并将结果存储在变量中

请注意,打印和返回不是一回事;将输出写入终端或控制台后,print始终返回None

您还使用了==相等测试,其中应该使用=赋值。平等测试是一种表达;它返回的结果为True或False,它不会影响与之进行比较的名称

您没有正确测试数字输入。有关如何正确处理用户响应(包括转换为其他类型)的信息,请参阅。表达式Distance==int==True永远不会为True,因为即使Distance包含用户输入,字符串值也永远不会等于int类型,int类型也永远不会等于True

次要的一点:您正在导入re,但从未使用过它。您可以安全地删除导入重新行

因此,这里有太多的问题;如果我把它们都修好,我会帮你做作业。我建议你把你的问题分解成更小的程序。一次做一件事。先把它做好。然后转到下一个。重新阅读以查看可能遗漏的内容。
