步骤一:捕获异常 在Python中,我们可以使用try-except语句来捕获异常。下面是捕获异常的代码: try:# 尝试执行可能会出现异常的代码# 这里可以是任何可能会抛出异常的代码块exceptExceptionase:# 捕获异常并赋值给变量epass 1. 2. 3. 4. 5. 6. 步骤二:打印异常信息 在捕获到异常后,我们需要打印异常信息。下面是...

python自定义异常也可用于触发非错误的情况,根据条件语句触发raise异常。用法 classFoundByExc(Exception):passdefsearch_by_exc(strlist,target):ifTrue:raiseFoundByExc("xxx")else:return"xxx"描述 搜索指定内容时触发异常。(1) 自定义一个异常类;(2) 条件成立,触发异常;示例 >>>classFoundByExc(...
try: 1/0 except Exception as e: print(e) 安全:优雅处理错误,知道哪里出了问题。 20. 重定向print输出 将输出导向文件。 with open("output.txt", "w") as file: print("这是输出到文件的内容", file=file) 持久:将信息保存,便于后续查看。

在Python中,和部分高级语言一样,使用了try/except/finally语句块来处理异常。 部分代码如下: defdiv(a, b):try:print(a /b)exceptZeroDivisionError:print("Error: b should not be 0 !!")exceptException as e:print("Unexpected Error: {}".format(e))else:print('Run into else only when everything ...
