function_name 是函数的名称。按照 PEP 的要求,函数名称的命名方式与变量的命名方式和格式一样。 函数名称之后紧跟着 ([parameters]) ,函数名称和圆括号之间不能有空格,圆括号也不能省略。圆括号里面是这个函数的参数列表,如果此函数不需要参数,则可为空。。 圆括号后面是英文状态下的冒号,表示此逻辑行结束,下面...
defoverspeed_rate(current,max,min):ifcurrent>max:return(current-max)/max # 超过最大时速,结果为正 elif current<min:return(current-min)/min # 超过最小时速,结果为负else:return0# 不超速,结果为0 这个函数用来判断车辆在高速上行驶时超速的比例。它接受三个参数,current表示当前时速,max参数表示当前路段...
