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 except (ZeroDivisionError, TypeError) as e: print(f"An error occurred: {e}") # 测试 print...
numbers=[1,2,3]try:result=numbers[5]/0except(ZeroDivisionError,IndexError):print("发生了ZeroDivisionError或IndexError异常!") Python Copy 在上面的代码中,我们首先定义了一个列表numbers,然后尝试将numbers[5]除以0。由于索引超出范围和零除错误,这段代码可能引发ZeroDivisionError和IndexError异常。在我们的except...
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...

类似if-elif-else语句，try-except也可以多分支。此外，异常语句还可以与else和finally配合使用。如果try中没有异常，跳过except；如果没有，则执行except中的语句，跳过else。最后finally内的都会执行。Similar to if-elif-else statements, try-except can also be multiple branches. In addition, exception statements...
Atrystatement may have more than oneexcept clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the correspondingtry clause, not in other handlers of the sametrystatement. Anexcept clausemay name multiple exceptions...

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 ...
