error:是代码错误,编译不通过,运行不起来。比如变量命名不规范,public类名和文件名不一致等。 exception:分为runtime exception和非runtime exception。 runtime exception:运行时异常,是程序内部的异常,如数组下标越界,空指针,类转换异常等。 非runtime exception:非运行时异常,一般是外界导致的异常,如IO e,class n...

Exception Handling Even when a programmer writes a syntactically correct program, the program may still error at runtime or execution. Consider the classic runtime error—division by zero. Because zero cannot divide a number, the Python interpreter displays a message informing the programmer of the...
runtime vs compile time numerical error python本身的小特性 注:这篇文章是读python github有感。 1. copy vs view 像普通的语言,都有明确区分引用(reference)和复制(copy),例如pascal的传参or传值,c++的&,但python并没有明确的定义。 定理:“python万物皆引用(object reference)” ...
