Python in 8 minutes (compared to Java) 

"Texas Smash" "Detroit Smash" Someone likes My hero Academia.

I can really see the benefits of learning Java instead of Python as your first programming language as someone who's just about to finish his first semester in computer science. Java teaches you A LOT of fundamentals that are done in the background for you in Python. The steps leading to learning Python if you know Java are also going to be much easier than the opposite.

My first programming language was C, so I loved Java when I started it. Then i discovered python! Thank you for watching, feel free to leave any feedback! like/sub to support the channel it helps out a lot : ^ )

This is a great intro to some of the differences, thank you.

In Java you could've done data.forEach((k, v) -> System.out.println(k + "=" + v)); Also for the hashmap: Instead import static java.util.Map.entry; Map map = Map.ofEntries(entry("Texas", "Smash"), entry("Detroit", "Smash")); If you learn Java properly, you can make the code as short as python, and (in my opinion) more readable

I was comfortable with python earlier and used to code in python as its very easy to code. It helped me build ml models too.But my company told me to learn java/cpp as it is more useful there. Now i forgot python and coding in java and feeling bad as i missed python 😔.

Cool, I'm gonna do leetcode in python from now on. That way I can more focus on the logic and pattern rather than the code. Thanks!

Thank you for this video! Starting to learn these two languages, very fascinating to see the similarities and differences between these programming languages.

I have used java for almost 4 years at work and used to LC in java for a long time. But now I have decided to move to Python because it saves time during the interview.

love you man! Thanks for your amazing videos and advice. I've just begun my leetcode journey and I'm loving all of the learning curves, steep and easy. Your vids are perfect for me.

Oh nice! This is really helpful, me trying to learn Python syntax

Actually in Java you can iterate over key/value pairs of hashmap too, using map.entrySet() method instead of map.keySet(), but still the syntax is not so concise as in Python for sure

You've got it all figured out. Python3 is the way to go for LC-style interviews. Would it be possible for you to make a video on the syntax and all for usage of various data structures in Python? This video could be just a compilation of all the operations commonly used in all the data structures in LC type questions. Basically just what would be enough to be able to convert english -> python code. Built-in functions used on the regular and other such tidbits. Having one 10-15 min concise video on this would greatly help!

The java code above is the naive approach. The above java code can be rewritten as Map data = Map.of("Texas", "Smash", "Detroit", "Smash"); System.out.println(data); data.forEach((key, value) -> System.out.println(key + "=" + value));

Can you please add tutorials for java . you explain really well

IMO I learned Java first and enjoy using it for interviews. I also think the language is powerful when using TreeMaps, PriorityQueues, as well as being able to use Lambdas to dynamically define sorting or comparators. Haven't used Python enough to know if it has those things out of the box.

This is so true! And I started brushing up on my old python 2 weeks before my technical interview, god wish me luck! LOL

Is it ok to use JavaScript in interviews ? I've heard we can use c, c++, Java and python but never heard anything about people using scripting language like JavaScript.

Hi sir As we know python is Comparatively slow because of its dynamically typing nature, being interpreted language and Global interpreter lock by garbage collection and also to tackle such issues we have like C extensions, threading and multiprocessing modules, Numba JIT, there is no one such standard python developer best practice to write the code which could match the speed of java and c++ a bit closer. So you being a python developer in such a big company,could you please share some standard applied practices to make the python code faster and make ourself feel we are confident about our preferred choice of programming language.. Thanks in advance

This is the best leetcode channel! That said I hate that you program in python. Too much is abstracted away, too much syntax sugar, which is not ideal when trying to learn.

It looks very clear but doesn't Java encourage better code and OOP? Readability?

Kinda sad nobody picked up on the MHA references

i kinda wish my school started with python instead of java, it is a lot easier to get into, and would turn away less people from CS we went Java (basic OO programming) -> C/ARM (memory) -> C++ (ds + algo) -> electives (ocaml, verilog, javascript, etc.)

Blows my mind how simple Python is compared to Java

So Neet man, thank you for the refresher and with a nice example!

1. The class name and filename should match only if the class is public, the visibility of public classes are throughout the project so it simplifies it. Single page application that isn't going to be reused have no reason to be public 2. var data = Map.of('NEET', 'code', 'Neet' , 'code'); would have acheived the same thing in a concise manner 3. data.forEach( (key, val) -> System.out.println(key + " = " + val)) Is a simpler one liner

I interview a lot of candidates, I don't know if this is a trend, but candidates who choose to do the coding in Python usually do better, and solve the problem I give them in time. For Java, it takes more time. Golang is in between, sometimes they write their own handy function during the interview that Python would have out of the box. Example: get max between two integers, or sum of all integers in an array, all these are one-liner in Python, you will need to write your utility function or import external library to do the same in other languages.

Finally someone who uses MHA as reference ;) 👍🏻

To be honest i liked the video until you added the elements to python dictionary by writing inside the dictionary , could have just wrote data["NEET"]= "code" , also same for java could have initialized the hashmap with the values or used Map.of ..

Don't forget about speed of this languages when you need to something real useful (not playing with console output),🙃

it could be done in other way..... dict={'neet':'smash','Neet':'Smash'} for i in dict: print(i,':',dict[i])

I'm thinking about learning some python because Im interested in machine learning. So far I only know java and sql

Java first semester python second semester. This video is very helpful 👍

void main() { System.out.println(" THIS IS JAVA "); var data = Map.of("Texas", "Smash", "Detroit", "Smash"); System.out.println(data); data.entrySet().forEach(System.out::println); } Using Java 21 with preview features. If executed inside the JShell REPL it goes down to 4 lines only, even less than the Python version :)

I'm glad I learned Java first. It would be really hard to learn Java after learning Python first

Texas, Smash... Somone's an All Might fan

i learned python first, java and c# second, yes its less code for python, but i didn't understand what it truly did, and i wouldn't be able to create as much new stuff.

Most of the times languages are compared just on syntax and how the code looks and all other aspects of the language are not considered. Also, many things in this video are not true nowadays. Java had a lot of innovation to simplify some of the syntax. But syntax isn't everything.

Java is more verbose, but that's a good thing to me, it's like more clear to me. Also, I like the WORA philosophy.

For me java is better maybe python is good for you but I love java

People say python is great but java makes more sense to me

Java is hella more verbose, but when compared in speed... Edit: 3:26 NEETCODE WATCHES MHA?

If you already know Java or C++ etc, and only want to learn python for interviews, I would not recommend it. Its a waste of time. Instead spend time on learning DS/Algo etc. On the other hand, if you are just starting, then learn python, it will help you in interviews as well. I say this because 1. Typing speed is never a bottleneck in interviews. Mostly you will type at best 100 lines or less even in language like java. Also there are tricks in Java or C++ to reduce no.of chars for example. If you really knew Java, you could do Map map = new HashMap(); // or var map = new HashMap(); instead of doing what the youtuber did. Also you can use modern java's Map.of() method to initialize some of the stuff. Essentially to say that if you already know a language, dont waste time learning new language, just refine your skills in the above said language. For example, most of the people who think they know java dont know some of the above tricks(even leetcode solutions have verbose java where they dont use lambas etc). 2. If you are learning new language only for the sake of interviews, you will not learn enough and have half knowledge. You will not understand the time/space complexity of things like s[1:] in python. You will not be in a familiar territory in an interview when faced with such challenges. Again typing is never a bottleneck for interviews. Now if this was for competitive programming etc, I would of course agree that using c++ or python would help you tremendously depending on the question. But if you already know Java, C++, etc just use it. Dont waste time learning a new language. Once you get into FAANG etc, then you can learn a new language and after 2 or 3 years, then you can use the new language for interviews again when you are ready to jump to another FAANG. P.S Look into firenvim and neovim to get intellisense on any website for the most part.

Awesome video! My first programming language was Python. And in my opinion, If you grow up on Python it is much more difficult to switch to Java than vice versa.

python more difficult than java because in heavy programming gonna be lost thats why brackets good idea

I am a java developer, I hate this. Since I have more experience in java, it is hard for me to switching to python. I am so confused.

Strict Data types and code compilation makes my day. Python sucks!

Oh Boy! Some people have no idea what they're talking about. Be happy by writing short code till your app crumbles badly under a load of millions of users due to slow performance. FYI -> I'm a VP of technology at an investment bank.

Java looks like the beginners’ coding nightmare

It it bad idea to choose Python as your first language.

import java.util.Map; public class Main { public static void main(String[] args) { System.out.println("Hello world!"); var map = Map.of("key1", "value1", "key2", "value2"); map.forEach((k, v) -> System.out.println(k + " " + v)); } }

why no one talks about the my hero academy reference "ah yes I like Detroit"

I guess Java looks better 😄

😒 still your survey about java wins.😛 Please code in java or c++ bcz for people who dont know python syntax but knows the concepts actually cant figure out.😐

but java code looks so beautiful

the days

Lets not talk about wich one is faster ok.

first of all if you learned java first at school then you went to the wrong school

No java leetcoders were harmed in this video

I am full blown machine learning engineer. I don't know why I am still watching this video lol

I prefer Java overall.

Personally, I wouldn't recommend Python to anyone serious about being a programmer. It teaches some bad programming techniques

Lies

C Programming Users laugh in pointer arithmetic

This make me watch MHA once again.

👍🏻👍🏻👍🏻👍🏻

Great video ! Jesus loves yall, may He bless yall as well !

Лишний раз убедился, что Java лучше, спасибо. На фиг эту змею.

Python sucks tbh and you won't find any job opportunity outside in the real world, advise from a Full stack dev.!!

TEXAS SMASH! XD *MHA music commences*
