What is the method for handling exceptions in Python?

One way to handle exceptions in Python is by using a try-except statement. The try block contains the code that may throw an exception, while the except block contains the code to handle the exception. For example:

try:
    # 可能会抛出异常的代码
    result = 10 / 0
except ZeroDivisionError:
    # 处理异常的代码
    print("除数不能为0")

In addition to the except block, you can also use the else block and the finally block to improve the exception handling mechanism. The else block contains code that will be executed if no exceptions occur in the try block, while the finally block contains code that will be executed regardless of whether an exception occurs. For example:

try:
    result = 10 / 2
except ZeroDivisionError:
    print("除数不能为0")
else:
    print("结果为:", result)
finally:
    print("结束处理异常")
