当异常和错误不可避免时,最好的方式就是让我们知道程序到底是哪里出了错,或者是因为什么导致错误,这样才能更好地让开发人员及时应对并解决。 loguru集成了一个名为better_exceptions的库,不仅能够将异常和错误记录,并且还能对异常进行追溯,这里是来自一个官网的例子 import os import sys from loguru import logger l...

The try and except blocks are used to handle exceptions. The assert is used to ensure the conditions are compatible with the requirements of a function. If the assert is false, the function does not continue. Thus, the assert can be an example of defensive programming. The programmer is mak...
Themock.create_autospecmethod creates a functionally equivalent instance to the provided class. What this means, practically speaking, is that when the returned instance is interacted with, it will raise exceptions if used in illegal ways. More specifically, if a method is called with the wrong ...
# 【拓展】Loguru:更为优雅、简洁的Python 日志管理模块 # 【一】引入 - 在 Python 开发中涉及到日志记录,我们或许通常会想到内置标准库 —— logging 。 - 虽然logging 库采用的是模块化设计,可以设置不同的 handler 来进行组合,但是在配置上较为繁琐。
一、安装python之后,调用graphics模块可能会出现如用报错,这说明就需要安装或复制文件graphics.py到安装目录下。 >>>fromgraphics import *Traceback (most recent call last): File"<pyshell#1>", line1,in<module>fromgraphics import *ModuleNotFoundError: No module named'graphics' ...
全局命名空间:当用户创建一个类或函数时,将创建一个全局命名空间。 局部命名空间:局部作用域中的命名空间。 命名空间关系图 命名空间系统可以防止 Python 模块名称之间产生冲突。 延展阅读: https://medium.com/better-programming/how-to-make-python-programming-more-e...
