我们可以指定捕获的异常类型,也可以使用通用的except来捕获所有异常。 三、示例:基本的异常处理 示例代码 # example.py def divide(a, b): try: result = a / b print(f"Result: {result}") exceptZeroDivisionError: print("Error: Cannot divide by zero.") exceptTypeError: print("Error: Unsupported ty...
except TypeError: print("Error: Unsupported types. Please provide numbers.") except Exception as e: print(f"Unexpected error: {e}") # 测试 divide(10, 2) # 正常情况 divide(10, 0) # 除零异常 divide(10, 'a') # 类型错误 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14...
print("start")try:print("发生错误之前")y=5/0# 分母为0的错误,try捕获到ZeroDivisionErrorprint("发生错误之后")passexceptSyntaxError:# 不是try捕获的错误类型print("A-报告错误")exceptZeroDivisionError:# 是try捕获的错误类型,运行该部分print("B-报告错误")finally:print("错误处理完成")print("Done")#输...
这样可以确保文件路径的正确性。 在try块中执行文件操作,并在except块中处理可能出现的异常。 6. 总结 在本文中,我们解决了“python pywintypes.error: (2, ‘OpenEvent’, ‘系统找不到指定的文件。’)”错误。我们按照以下步骤进行解决: 导入必要的库。 检查文件是否存在。 解决文件路径问题。 通过按照以上步骤...

The plain try-except block will catch any type of error. But, we can be more specific. For instance, we may be interested in only a particular type of error or want to handle different types of error differently. The type of error can be specified with the except statement. Consider the...
