Hey Corey, please make a video on MRO (Method Resolution Order) in Python

[@almohtarifchannel6702]

Corey Schafer how we can loop 2 lists witout same lenth

[@coreyms]

Like I was saying in the video, zip will stop after the shortest list is depleted. zip_longest from the itertools module will go to the end of the longest list and have filler values for the shorter lists. Watch my video on itertools to see an example.

[@dharaneeshwaranravichandra6159]

Please make a video on "How Django processes a request ?"

[@expat2010]

I'm 79 years old, been studying Python for about 6 months, and I got to tell you I get so damned exited with the stuff I learn from you - no other teacher, paid or free, has come close. I just hate to tear myself away from videos like this! I don't have a lot of money, but I'm gonna send you a few bucks - buy a toy for your beautiful dog. :)

@@elghazouanimohammed6639 I deal with cryptography and thus large numbers a lot. Having some human readable constants is nice, such as 2**32 if it were written out. Sometimes it even just helps for understanding "oh, it's like a billion" without having to break out the cursor to count each zero.

Your videos are so high quality! All the info was very useful specially the dir(). God I wish i knew that earlier xD Thank you so much :) I followed your django tutorials and now have 4 good personal projects under my belt! Your tutorials were my foundation of Django. One thing I'd really want you to cover is unit tests. They seem to be a huge part of companies and I think its an important topic to cover and would be helpful to other viewers as well.

[@williamreames2228]

Although I didn't know about zip (8:52) and it does seem pretty helpful, it looks like you could get an equally organized structure if you use a dictionary instead since the two lists are inherently related and do something like: for name, hero in dictionary_name.items(): In any case, great video and I definitely managed to learn some things

[@starecekmichal]

First of all, I have to say that I'm very thankful for this videos.

[@RufusVidS]

I've worked with Python for many years, and some of the features mentioned here are only in the most recent versions of python (like f-strings). I work in environments that have older versions of python (even the now obsolete Python2.7) without these features I think it would have been helpful if the version of Python where the feature was introduced was mentioned in the video. This is not meant to be a criticism, this video is great!

This would be faster than enumeration. You could timeit yourself. I would prefer this one to enumeration

[@krishnakumarshankar4576]

Why can't you do this

[@SorinOltean77]

@Parker Anderson: your method is correct for sure but is not pythonic. The Python way of doing things tends to simplicity in code writing, hence the enumerate function. Even the fact that you can loop through a list with just "for item in items:" is something really easy to write and understand later.

When I take a class or an interview they ask me to solve a problem and not syntax questions. I wish there were more videos on how to solve problems so I can see how the logic works and how to approach solving the problem.
