ctime(0) was giving me Dec 31, 1969 19:00:00 I'm guessing that's because I'm in New Jersey and during winter our 'standard time' makes us GMT-5?
Yes, you are spot on. ctime represents what local time would have been for a given second value. And that is why mine doesn't show the hour, because I fall into GMT in winter. Thanks for wataching!
Quite informative, but everyone knows the only valid datetime format is YYYY-MM-DD HH:Mi:SS :)
I prefer DD-MON-YYYY - I work with oracle a lot :) Thanks for watching!
Great video. I like that you didnt cut out the mistake. This shows that making not everything perfect at the first glance is normal. The inly thing i am missing ist the explanation what the __init__.py is for. You said you would recommend adding an extra file for the function, but why? That would be interesting. Thank you.
Glad you like it. The mere presence of __init__.py tells python that the folder is a package. When you import the package any functions in __init__.py will be executed and made avaialble to your code. You may not want to use all thew functionality of a package and so putting them in sub files lets you import just what you need, which is fater. Hope this helps and Thanks for watching!
With all due respect and understanding how well intended this video is, I would like to mention a few things I am missing or would do differently: 1. This is meant to be an introduction to while loops, and the example is a nested double while loop. While (yeah another "while", lol) good to know that's possible, just a bit much first time round for something new. 2. A while loop is useful when you don't know beforehand how many times you need to execute a block of code. 3. Initialization: ensure variables used in the condition are initialized before the loop starts. 4. There's also a "continue" statement. Skips the rest of the code inside the loop for the current iteration and jumps back to the condition check. 5. Pitfalls like infinite loops, unintended infinite loops and off-by-1 too many/few times looping through the code. I am just trying to be helpful, feel free to ignore this comment if you don't like it.
First off, thanks for the feedback and for watching! In hindsight I think that trying to start out writing a mini game was the wrong setting for using loops, I focused too much on the problem and not the area. After this video I descided to focus on specific examples. I havn't done this in future videos and have instead created longer videos to write proper examples and exercise what has been learned. The only thing I kind of disagree with you on is 4 and use of continue. I dislike continue, it's too much like go to for me and I think devs should think more about loop handling. That said I did do break which is just a littlle hypocritical of me. I actually started using these in python recently and am still on the fence on wheteher or not they should be used. It is however part of the language so I should have covered it.
just found a gem i guess. nice video!
Glad you liked it. Thanks for watching!
is this ibxtoycat or foxynotail?
I am neigther of those. Although I do have a gaming channel. Thanks for watching!
@the_code_guy whats your gaming channel? hope you keep making python content, the way you explain things is amazing! cleared up alot i was confused about
Glad you like them, definately plan on continuing. Here is the other channel www.youtube.com/@altek2k. Thanks for watching!
@the_code_guy youre welcome! hey do you have instagram? could i talk to you privately about a coding matter? like.... 5 minutes of your time to see if i can show you something interesting, and if i cant then alright. I'm not a programmer, im a cancer patient, but i am attempting to program a game but im having trouble with it
I think I’ll have to play with this a bit to really understand it. I think that it would be best to use examples that align better to real case scenarios, like when you are using 3rd part libraries like FastAPI, etc
Thanks for the input. I don't normally like comparing to 3rd party libraries as changing them can become a real pain. But will definately keep in mind to find a way to point out real world examples in the future. Thanks for the support!
First comment. Thanks for this and the other video. They are brilliant.

How to share package with other python files in OS level?
You would have to install it as a python external packge into python or your venv . There are several ways to do it. Host your own pip server or do a local pip install. Pycharm makes it prety easy if you just want to do it locally. www.jetbrains.com/help/pycharm/creating-and-running-setup-py.html If you want to install in a new venv pip install -e <<somepath goes here>> This is a pretty advanced subject. I can add to my future video list if you would like me to cover. Thanks for watching!
It would be useful indeed. Personally, I upload my packages to Github and clone it from there
really nice, thanks for posting this. I think try catch blocks like your showing here are great, makes for readable code instead of mad if then elsifs and is more robust
Thanks for the continued support!
ah, good old regex, your video is great. I remember fondly pcre and using its 'x' flag to format complex regex over mulitple lines, with comments to make them readable - I dont think that is available now, or is it ? I'm going to look and find out also, muliple line matching of records starting with a given string pattern, in Python I've ended up doing that programatically but I used to do that also with pure regex in Perl but I dont write in Perl any more. sometimes regex can become like line noise though and when it does, I run away !
I'm not familiar with the x formatting but you can still add comments but I find it makes it even harder to read so I tend to avoid. I always hated regex, coming from a dB background originally they were always way to slow to be useful. When I moved over to other languages I decided it was time to force myself to learn them properly. Glad you liked it, thanks for watching and sharing!
@@the_code_guy its the 'x' and 's' flags I used to use in perl but its a long time ago so I could have had that the wrong way round but I believe translates to python with something like : pattern = re.compile(rf""" ( {record_pattern} # md5sum followed by 2 or 3 numbers ) (.*?) # Non-greedy match for any characters in between (?= # Lookahead assertion {record_pattern} # Next checksum pattern |$ # Or end of string ) """, re.VERBOSE | re.DOTALL) permitting me to format my horrible regex across multiple lines and also match multimple lines in a file or input I got so excited to see this I blogged about it as I never thought to try this in python, so thanks to your video I did. This makes me a very happy camper.
very nice guide, thanks. You've made this very clear. I like how you dont type everything to within an inch of its life and only for your lib / module, nice touch. I suppose if this were a strictly typed language there would be no real choice but to type everything but python is letting you make that call
Yes in python they just help me by letting me know if I'm about to misuse a variable and so I only use them where the code is likely to get complex enough that I will lose track. Great for a reminder when maintaining the code too. Thanks for the support!
Thanks for your clear explanation

best regex tutorial ever

Had an issue with some minor trig. If I used sin(x)/cos(x) I got a number wrong to at least the tens place. If I used tan(x) the result was accurate to the hundredths place. Crazy
Floating point maths is just weird. The margin for error will be greater in the first because you are calculating based on two numbers. 0.1 * 3 highlights the errors slipping in. You could try casting the cos and Sin calcs to decimal before the division and see if it makes a difference. You won't need to cast to strings you can just put cos and sin inline. This probably won't be a great amount of use as floating point issues can not really be solved only managed via rounding. Hope this helps and thank for watching!
@@the_code_guy Yeah, that's a good idea. May give that a go. I still am baffled why such a big difference in the results. See, in Mathematica I had the opposite problem. I couldn't get a result I knew I should be getting. Used all the compact trig forms. Turned out I needed everything more-or-less in separate trig forms --- sin, cos....like that. I can see having SOME difference in results, but geeze my results were way off. Nevertheless, thanks for the response, appreciate it.
I thought ChatGpt delivers good results for regex expressions.
Never tried it for that. I used to be so bad at them I now try and craft them whenever I can so I don't forget :) Thanks for the support!

You learn something new every day. Didn't realise it had a json method. Wondering if I just kept using ujson because it was fast. Thanks for the info and for watching!
#0:30 - not always. I like YAML. I like being able to use anchors to avoid duplicate data.
I have never come across a service with a YAML end point to date are they becominng more prevelent. Used a lot in dev ops Config files though. Thanks for watching and adding your perspective.
@@the_code_guy - I do indeed work as a DevOps technician. Puppet and lately Kubernetes/Helm is where I encounter YAML.
Instead of printing and then needing to awkwardly search for something in the console while we're watching, you could use the debugger to inspect the data. Much faster and doesn't require you potentially needing to have a jump cut in your video because you spent more time than you care to admit looking for something in the console. Also, at 12:05 - why did you f-string the print when all you printed was definition? Definitely an unnecessary f-string.
I would like to say it's becuase I havn't introduced the debugger yet, but in all truth, just never thought of it. Thanks for the suggestion. On the f string, it's because I intended to use it. Which I do at arounf 12:22. Thanks for the feedback and for watching!
I'm still confused on why you'd even need the else. The whole point of a try block is "this bit of code might not work as intended in all situations, so try it and then catch XYZ Exception if it fails". So putting the "print(result)" after computing result would be the exact same thing as putting it in the else. The only use, though it seems a bit -dumb- unnecessary, is if you want to do a bunch of potentially unsafe operations in the try and then the else is "if everything succeeded in the try, then move on"... like a transactional kind of operation. Though, you could still just put that into your try block since most things (at least in Java, for example) will actually file if anything in the try block fails. Example - a transaction will be rolled back if any statement, like a save or update, is attempted in a try block but something else in that try block threw an error.
It really indicates that the code ran successfully so everthing you expect to be there is and it saves you from checking a load of invalid state stuff. The reason you might want to do a load of unsafe code in there is if you are working with multiprocess. Exceptions in there are hidden unless you specifically handle them and have a way of bubbling them out. Which means that all your code in those cases are really wrapped in try/catch to ensure your main process knows about them. If the code is more complicated I tend to ignore else and set an error occured indicator so I can control the code later. Hope this helps explain my thoought process. Thanks for the thoughtful comment and for watching!
I wish I found you earlier! TYVM mate!
Gald you found it useful. Thanks for the support!
Great video! I often wonder why your f strings work because for example... for customer in customers['customers']: print(f'{customer['Name']} - {customer['Occupation']}') Will not work due to f strings/single quotes. I just end up using double quotes on the outside. Other than that, learned some new things :)
I do occasionally double quote the outside when I get that error but it’s rare. my go to is always single qoutes unless it’s easier not too. Could be python version differences that let it work for me and not you. Glad you found it useful. Thanks for the support!

Thank you for these lovely videos! I've only just finished episode 1 but I wanted to jump forward just to let you know that your lessons have reminded me of the passion I had for coding when I was a kid.
