在Python 3中,上述代码会引发SyntaxError: multiple exception types must be parenthesized错误。 修正此错误的方法 要修正这个错误,你需要将你想要捕获的异常类型放在括号中,并用逗号分隔。例如: python try: # 尝试执行的代码 pass except (ValueError, TypeError): # 正确的写法 # 处理这些异常 pass 示例:如何...

To investigate exception groups, you decide to adapt your earlier code to learn how you can deal with multiple exceptions. For this, you use the specialexcept*syntax: Python # catch_all.pyexceptions=[ZeroDivisionError(),FileNotFoundError(),NameError()]num_zd_errors=num_fnf_errors=num_name_er...
multiprocessing是一个支持使用类似于线程模块的API派生进程的包。该包同时提供本地和远程并发,通过使用子进程而不是线程,有效地避开了全局解释器锁。因此,multiprocessing模块允许程序员充分利用给定机器上的多个处理器。它同时在Unix和Windows上运行。 该模块还引入了在线程模块中没有类似程序的API。这方面的一个主要例子...
PEP 8: multiple imports on one line 解决方法:不要在一句 import 中引用多个库,举例:import socket,urllib.error最好写成:import socket import urllib.error PEP 8: blank line at end of line 解决方法:代码末尾行多了空格,删除空格即可 PEP 8: at least two spaces before inline comment ...

In this tutorial, you’ll focus on how exception groups can handle multiple unrelated exceptions at once and how this feature paves the way for task groups, which make concurrent programming in Python more convenient. You’ll also get a peek at some of the other, smaller features that’ll ...

使用通用的 except Exception as e 捕获其他未预见的异常,并输出错误信息。 四、多个 except 块 我们可以在一个 try 块中使用多个 except 块来捕获不同类型的异常。Python 会依次检查每个 except 块,直到找到匹配的异常类型。 示例代码 # example_multiple.py def safe_divide(a, b): try: return a / b ex...
