Errors can be corrected during compilation of source code or even at runtime. It can syntax error or semantic error. Exceptions are caused during run time when the interpreter gets some unexpected data. They are handled using try and except technique. Hey Krish, just wanted to say Thanks a lot for uploading these amazing videos. I've recently started watching your playlists and I really feel confident and motivated about my Data Science journey.
Errors could be identified & corrected during compile time; whereas Exceptions can be only identified during run time and can be handled with try catch
error = We take error as the program syntax is gonna wrong somewhere or something. Exception = It basically means that the thing is out of the league for the program example:- we make a function to find the number is even or odd and when the user gave input it gave the string which is out of the league for the defined function. It through an exception
Hi Krish! Thanks a lot for creating awesome Videos, they really helped me to grab my first data science job. Please create videos on Adv. optimisation like genetic optimisation And simulation
Error mainly happens during run time .. it belongs to uncheck type ..... but exception can happen during runtime as well as compile time also and ofcourse exception can be handled but not the error.
Respected sir, I am new to the whole concept of machine learning and would like to learn it to an extent that I will be able to do some real world project in my collage using ML.. I just wanted to know if this playlist will serve my purpose sir. And by the way, your teaching is excellent...its just like how a friend teaches stuff...Thankyou!
errors are occurred due to wrongly coding, or wrongly entered input & exception is a diversion of program from throwing an error & smoothly showing an error without stopping the program.
Can anyone give me the answer of this question? When I write except Exception: print(Exception) output is '' but when I write except Exception as ex: print(ex) output is 'name 'b' is not defined' why "as ex" is changing the output?
Because Exception itself is a class, in the first case '' is getting printed. In the second case you are capturing whatever exception has occurred in the try block using 'except Exception as ex', therefore this ex variable has the specific exception that has occurred in the try block
hey krish ! I am a 2020 engineering graduate living in Mumbai. You made an entire video about how to follow your structured playlist to become data scientist .Now suppose I follow it and only do machine learning and skip the deep learning part can I still land a job in Mumbai ? if yes , how much would I make as a fresher? can anyone else reply as well ?
Exception handling is not an advanced concept. It's also pretty useless in most cases. What an exception usually tells you is that you made a software design mistake. For bugs that you can anticipate it can be used as a catch-all debugging tool. Good design never even gets into that kind of mess. The main scenarios where you absolutely need exceptions are if have to work with incomplete APIs that do not let you guarantee correctness by design (i.e. other people's bad software design) and then in situations that change in real-time in which the code can never anticipate what will happen.

hello brother , can i communicate with you ?

Errors can't be handled whereas Exception can be handled during run time!

great stuff Krish. Learning something important everyday from you. Can't thank you enough.
Amazing, I always use generic exceprion. Came to know how to use diff types of exceptions. ❤
Compile time is concerned with preparing the code for execution, while runtime is concerned with the actual execution of the program.
when an error occurs, it stops the execution of the program abruptly, where as exceptions can be handled and helps us to exit the program gracefully.
Thanks lots for your amazing tutorial .
Sir I am requesting you please make videos regarding data structure and algorithm with real life examples.
Error stops programme once it happens whereas exception handling is for defining various scenarios if they happen user understand the mistake well.
Errors can be broadly classified into 2, Syntax Errors and Non-Syntax Errors. Non-Syntax Errors are called Exceptions

Error is that you will get at compile time and exception is basically occur at runtime
Great stuff by @krish naik
The example provided in the last minute was pretty useful
The examples are so good ❤

Perfectly explain
Can any one help me how to get numbers for each lines in python as shown in the video....
Got it
View--> toggle line number
Awesome !
Priceless
Sir can you plz make videos on exercises related to python for beginners , intermediates and advanced
error can be due to syntax issue however exception are always syntactically correct.
Thanks Krish
Great Explanation !
What it's mean if writeen
excep exception as e:
raise e
errors are occurred due to wrongly coding, or wrongly entered input & exception is a diversion of program from throwing an error & smoothly showing an error without stopping the program.
How can we access the variable outside the try block?
error - systax error occured on while compile our code , exception is errors while execution
Hi sir, how can I have a conversation with you. I have some issues regarding academic and personal. Please if you have time, give me some indications.
Join the telegram grp link of which is in the description
Exceptions are violation to defined rules.
Errors are exception that are not handled and occurs during runtime.
Thank u sir, u made it clear !
Error is something wrongdoing in your code detected by compiler whereas exception is somehow a warning made by developer at error prone area.
Ei trace call back error kya hai?
Can anyone give me the answer of this question? When I write
except Exception:
print(Exception)
output is ''
but when I write
except Exception as ex:
print(ex)
output is 'name 'b' is not defined'
why "as ex" is changing the output?
Because Exception itself is a class, in the first case '' is getting printed. In the second case you are capturing whatever exception has occurred in the try block using 'except Exception as ex', therefore this ex variable has the specific exception that has occurred in the try block
@@rishikambhampati2862 Thank you for the explanation
How to print error line no in exception handling
isn't there a playlist for this?
Check the description
Done
Sir, why we can't use else block for closing the database
What excpetion may come how will you know when performing complex operations
Sir, can we perform the remaining operations by skipping that particular exception
#awesome
Pls add the videos on series of genetic algorithms after adv python series. Thank You Sir
If end user give wrong input called error
Sir, can we perform the remaining operations by skipping a particular exception error
If there is no dependency, then you can skip and go continue from next
Can the Exception class handle multiple exceptions at a time?
They can be nested, however, Python doesn't have real parallelism, so it's always one at a time anyway.
hey krish !

can anyone else reply as well ?
bro hue kahi placed data science me?
👌
❤✨
U should dictate in hindi 🙏🙏
20:00 so basically whatever happens
The database will always be closed

This is not even basic python. where is the advanced? lol
