问题 Sounds like I'm missing something extremely simple, I'm trying to set a breakpoint in my python code using: if(some condition): pdb.set_trace() My error in the code comes after a large number of iterations..difficult to debug using print etc. I am able to print stuff when the condition hits but I would like to set brk-pt. --EDIT-- Actual code: import pdb if (node_num == 16): print node_num pdb.set_trace() 回答1: I am not sure as to why your code isn't working, but what you can do is on your

Where to find the pdb files for Qt's dll?

心已入冬 提交于 2020-01-31 07:36:33
问题 I am debugging a Qt application. Where can I find Qt's debug dll? I am using vs2010 on windows. It says it needs the pdb file for many .dll from Qt. 回答1: The Qt SDK does not come with debugging symbols for release builds. You have to compile the whole thing from source with the correct compiler flags to get the .pdb files you need. See this bug report. 回答2: As of Qt 5.9, the PDBs corresponding to the Windows distros are available as a separate .zip file for download from this archive: https:/

Python 调试库 pdb

文章目录 一、Python pdb 简介 二、Python pdb 使用方法 1、import 使用 2、命令行直接用 三、Python pdb 运行简析 之前写比较复杂的 shell脚本的时候,经常会用 -x 来调试,很方便也很清晰。 然后我就在想 python 脚本是不是也有类似的调试方法。 一查果然也有,就是 pdb ; 感觉也挺好用的,这里记录下使用过程。 一、Python pdb 简介 Python 的 pdb,是其自带的一个调试库。 它为 Python 程序提供了交互式的源代码调试功能,是命令行版本的 IDE 断点调试器,完美地解决了不借助工具进行调试的问题。 二、Python pdb 使用方法 使用方法有两种: 1、import 使用 # test.py import pdb pdb . set_trace ( ) a = 20 b = 10 c = 15 e = ( a + b ) * c print "(a + b) * c =" , e e = ( ( a + b ) * c ) print "((a + b) * c) =" , e e = a + ( b * c ) print "a + (b * c) =" , e 2、命令行直接用 python3 - m pdb test . py 三、Python pdb 运行简析 当运行这个程序时

Attaching a process with pdb

问题 I have a python script that I suspect that there is a deadlock. I was trying to debug with pdb but if I go step by step it doesn't get the deadlock, and by the output returned I can see that it's not being hanged on the same iteration. I would like to attach my script to a debugger only when it gets locked, is it possible? I'm open to use other debuggers if necessary. 回答1: At this time, pdb does not have the ability to halt and begin debugging on a running program. You have a few other

递归函数初步理解---python实现(汉诺塔问题)

不羁岁月 提交于 2020-01-18 22:36:27
递归常被用来描述以自相似的方法重复事物的过程,在程序中指的是在函数定义中使用函数自身的方法。 递归是一个树结构,分为递推和回归的过程,当递推到达底部时,就会开始回归。 问题描述:A比B大两岁,B比C大两岁,C的年龄为18,求A的年龄? 代码实现: def age(n):   if n == 1:     return 18   else:     return age(n-1) + 2#这个相当于一个断点或者称为调用点 print(age(3)) 可以用python中的pdb来看程序的具体执行步骤,在代码中加入以下代码即可 import pdb pdb.set_trace() 递归的运用较为著名的就是汉诺塔问题 来源: https://www.cnblogs.com/zoutingrong/p/12210434.html

all variables are undefined in python debugger

蓝咒 提交于 2020-01-16 18:40:09
问题 I'm facing a very strange issue on Python 3.6. In the middle of my code, I call import pdb; pdb.set_trace() to debug some code. And then I'm not able to debug properly, for instance: (Pdb) abc = 3 (Pdb) [abc for _ in range(2)] *** NameError: name 'abc' is not defined (Pdb) [abc, abc] [3, 3] It seems like whenever I use list comprehensions, there is an issue of variable not defined. However, if I call the debugger right after I open Python, I do not observe this behavior, everything runs fine.

Pdb Crashed: Cannot set breakpoint

问题 I suddenly cannot set any breakpoint in my python program. Note there are two (Pdb) showing up. I wonder if the Pdb was damaged before. I did try to step into some compiled C++ code in an abc.so file using Pdb before this issue started happening: -> print('haha') (Pdb) (Pdb) Traceback (most recent call last): File "high.py", line 38, in <module> print('haha') File "high.py", line 38, in <module> print('haha') File "/Users/ludaming/anaconda2/lib/python2.7/bdb.py", line 49, in trace_dispatch
