How to Use a Debugger - Debugger Tutorial

In this video I will be teaching you how to use a debugger. This debugger tutorial will show you how to debug, answer the question: what is debugging and show you how to use the vscode debugger. We will be debugging python code in VSCode but this tutorial will be teaching general debugging concepts that should apply to all debuggers.

What tutorials do you want to see next?!

[@therealosose]

Projects you can do with golang

[@simonboteroaristizabal687]

How to use PyCharm in an advanced way

[@simonboteroaristizabal687]

Or how to code a pygame game for mobile!! Should be complex enough and very cool

[@gidartsproduction5439]

School management system software tutorial_02

[@EAU183]

An efficient way to use EMACS as a IDE.

[@dpskane]

there is one part about debugging that you left out, which is sometimes quite important: conditional breakpoints. Because due to an exception you might know the line where the error happens and certain values of variables at that point, but if it's inside a big for loop you might have to click "continue" hundreds of times before you get to the one loop that breaks everything. In your code e.g. there could be an exception when "num = 349". you don't understand, *why*, but you either have to change the code or you need to put a condition on your breakpoint - otherwise you might have to click a bizillion times before num actually turns into 349

[@aanisnoor229]

Thank you!

[@Lazerbeam50]

This is easily one of the most useful programming skills I've ever learned. Thank you so much for explaining everything so clearly!

[@Raghav1205]

Hey Tim could you do some advanced data structures stuff like graphs and graph algorithms and how to implement them

[@dhruvgupta3177]

right when i was getting stuck with a bunch of bugs... TIM SAVES THE DAY!!! thanks tim keep doing what u do i got my real interest in python bcz of u

[@stevencvisuals]

Nothing more annoying than a bad indentation -_-

[@tempor8336]

Steven Cheung or mixing = and == searching for the error during 3 hours and then figuring it out.

[@mandem5176]

I remember watching your coding tutorials and stream and here I am 4 years later, back for some nostalgia.

[@databridgeconsultants9163]

Thanks Tim . Your Videos are Superb . Atleast you make videos which are directly implementable in real life projects . Great Job man .

[@hanweiz84]

Thanks Tim. Felt like I somewhat "levelled up" after watching your debugger video. I have been printing debugging statements within my code the entire time!

[@juliajulsen5623]

Thanks for the video! I also find myself using the debug console in VS Code often. Extremely useful tool

[@AliAliOxenFree]

great video. clear, concise and to the point. no extra fluff. earned a sub!

[@Moonlight-jx2sj]

I think you missed the main part: how to set up the .json file for debugger.

[@mariany4691]

It's usually very dependent on the language you're coding in

[@_sammy]

I know most people who will watch this video probably program in either Python or Java, but for any of my C and C++ programmers, I highly suggest learning how to use gdb. It runs in the command line so it’s really light weight. I’m sure there are tons of tutorials online. It’s really powerful and save you from tons of headaches, speaking from personal experience 😅

[@therealosose]

I just needed this thanks tim!!

[@noe1448]

Thank you so much for this video, so eloquent as usual !

[@qorbanimaq]

Really helpful! Thank you, Tim.

very clearylt explained Tim, thank you very much!

[@Bennilenny]

I knew about debugging but NOT ABOUT THE STEP BUTTON !! thanks, Tim.

[@MysteriousK69]

Would love to see Android game development

[@peterv3122]

This is a great video. Thanks Tim!

[@toreger2852]

Third video was the charm! Still the best ground-up explanation two years later :))

[@TechWithTim]

Glad it was helpful!

[@datarobe]

This video is very helpful, I searched a lot but was unable to get step by step procedure to use VS code Debugger for Python ( even the VS Code document does not give this level of clarity ). Thank You. P.S. - I am almost new to Python ( Actually any programming language ). 😊

[@himanshuagrawal2014]

Excellent Video and thoroughly explained, Stay Blessed. Thank you so much.

[@saxsafon]

Thanks, Tim! Just in time

[@premkatta1128]

Thanks, simple and useful video !

[@paramjangale5549]

Really helpful!!

[@aanisnoor229]

Thank you!

[@umerselmani6799]

Idk why, but I guess I need a bit more explanation to wrap this thing around my head, all is good, I suppose I will have to get my hands dirty with this to grasp the idea of the debugger. Thank You.

[@rameshahparameswaraiah6908]

Well explained

[@saminchowdhury7995]

Thank you so much master This was very helpful

[@TechWithTim]

Glad it helped!

[@biblicallybased]

I seem to be having issues using the Flask debugger in VS Code where relative imports prevent the debugging from happening. What should I do?

[@hemanth6951]

One of the best editor

[@adityachoudhary1637]

great video keep posting more videos like this😀

[@redrum4486]

Awesome! I used to get frustrating runnign the debug and it would just run the app - ALL because i did not include breakpoints before hand xD

[@top5things968]

Thank you 🎉

[@himbary]

Thanks! No one talked about how it actually works

[@robosergTV]

dude saved my ass at my job, thanks :)

[@superbroker.dxb007]

amazing amazing. You will go places my friend.

[@JamesTJoseph]

Conditional breakpoint, it is helpful when looping through an iterable.

[@dineshsen1807]

Really helpful

[@lohwaiseng]

MaY i know what happens if i enter a debugging mode of a unknown board assuming that I know wat the processor is, and I used the relevant tool to get into its debugging, what would I see in the IDE (programming interface software) ? Am I able to connect to the boards RAM & EPROM chip?

[@FirstLast-gk6lg]

I would like to see overviews of wide concepts. For example look at a full stack project and give a top down overview of what the technologies are and what they do

[@Kvothestark26]

I love your videos Tim😍😍

[@karlnassar8646]

What is the color theme he is using?

[@bouloukosxontropoulos7436]

Really great video !! By the way what font family are you using ? It's really good...especially how the def sticks out ! Is there a trick to do that?

[@stefaandumez2319]

I have the same. Only thing I did is to use the Monokai color theme. You can check out if it works for you.

[@gmc9753]

I thought a watchpoint is when the debugger stops when a variable changes or when it hits a certain value, or is watch and watchpoint different in VS code.

[@abhinavkuruvilajoseph9274]

i understand but, which extension I should download for debugging in vs code(python code)

[@doriboaz]

Tim hi what about conditional break points usefull for convergence math and for loop analysis.

[@gregoryfenn1462]

How do you debug memory layout and system registers such as MMU registers and other CPU peripherals?

[@t_tek760]

Thanks 🙏

[@frankkevy]

I finally understood it

[@TIMJR625]

Great video!

[@TechWithTim]

Thanks!

[@Dogberto999]

9:45 - Yeah, denominator goes down (or on the bottom of the fraction). That's how I remembered it.

[@rektm8141]

love the videos tim

[@TechWithTim]

:)

[@desislavaandreeva4359]

I had so many problems with the debugger in VSC...it was working fine a few weeks ago. After an update, it started playing up. I normally press F5 and then go through the code with F10...I checked the config file, I keep restarting the app and finally, I accept it to use it manually, I even raised a query to Microsoft and nothing, the case was closed automatically ... I hope you guys fix it soon.

[@DaniloSilva-pl3sq]

Neat! Really spetacular.

[@akshitagarwal1309]

What theme are you using in VSCode? Looks cool.

[@Tech_Eshwar]

Thanyou so much

[@me_debankan4178]

why my array showing in int[8]@12 in variable part of debugger ?

[@gidartsproduction5439]

Please Tim, are you going to continue with the software you just mentioned previously about school management system or you were just giving us a quick foundation?

[@TechWithTim]

I do plan on continuing it, just takes a while to film and code it all out

[@sakman27cap45]

It is cool to see live comments after reloading the page ;)

[@vaeshethblade931]

This is a decent tutorial for editing a known file, but when a program is dumping straight to memory, how can you find where it's going so you can debug it? I can hack the crap out of any file you give me, but I have a game that "hides" its files by placing markers in the save file and taking queues from memory in real time. Debugging is the answer to the problem, but I can't figure out how to locate the memory file I need to hack.

[@Laci4465]

Is the code that you show/use here on Github?

[@Lukas-zl5zs]

Thanks

[@jhudk2d]

I have a python script that uses ArgumentParser(). How can I make the debugger run the code with some defined "input" as the argument to the parser? Sorry if it's a stupid question, I have started learning python recently and have no previous experience with programming either.

[@jhudk2d]

Should I just manually define a default value? I answered myself :)

[@kunalbhatt4333]

I started learning to code in 2015, better late than never!

[@saisiddhartha5375]

The best thing that you could do

[@samsunggalaxyj7816]

Where we can see the output and where we can input something?

[@night23412]

holy shit this is an invaluable video

[@user-vw3pr5gq9g]

Thank god I see this right now after finishing two homework...

[@sagarganiga3417]

when i click on debugging only 2 options are available that is pause and restart. rest are not accesible

Sublime theme in vs code is really bothering me.

[@chriszink5225]

Please do more of these

[@chakibbounoun2349]

thanks maan

[@Mo-tf9jb]

Can you also debugg functions that are called from another file? Let's say I have a module 1 with a function and import this function to module 2. Can the debugger jump into the function in module 1? Best

[@n7s134]

yes it does that by default as of 16 dec 23
