File"err_logginginfo.py", line 6,in<module>print(10/n) ZeroDivisionError: division by zero 使用logging不会抛出错误,直接输出到文件中。logging可以允许你指定记录信息的级别,级别由低到高分别是debug、info、warning、error、CRITICAL等级别,当定义高级别的时候,低级别的信息不会输出,这是把日志信息输出到控制...
print(f"{__debug__ = }") if __debug__: print("Running in Normal mode!") else: print("Running in Optimized mode!") This script explicitly checks the value of __debug__ in an if… else statement. The code in the if code block will run only if __debug__ is True. In contra...
python3 -m pdb debugprint.py (Pdb) 显示已经执行到 debugprint.py 文件的第二行的程序文档。而后等待输入后续调试指令。 输入1,显示当前所调试程序的所有代码(此处省略显示)。 输入n,进行单步执行。 输入q 退回到命令行状态。 。。。 除了一步一步地调试,也可以在程序中使用 pdb 模块。 例如下面的修改,执...
