Python checker allows to check your Python code syntax (Python 3), and find Python errors. This Python code checker tool highlights and goes to line with a syntax error. To check your code, you must copy and paste, drag and drop a Python file or directly type in the Online Python ...

•Python定义了很多不同的错误或异常类型，表述不同类型的错误，如“除0错误(ZeroDivisionError)”、“文件未找到（FileNotFoundError）”、“导入错误（ImportError）”等。•所有内置的错误异常类型都是从一个最基本的异常类BaseException派生出来的。大多数异常类是从BaseException类的派生类Eexception派生出来的。Zer...
