Hey Krish. Thanks for uploading these videos. They are really helpful. One small suggestion, when you talked about the index(value,startIndex,stopIndex) method, you missed out on specifying one important point: When all the three parameters are mentioned in index(value,startIndex,stopIndex),the list searches for the element with the given value from startIndex to stopIndex-1 my_list=[1,2,3,4,1] my_list.index(1,1,4) -> this returns the error 1 not in the list my_list.index(1,1,5) -> this correctly returns 4 It will be helpful for every one if you can emphasize on this assumption.Thanks

Why Can't I directly assign the appended list to a new list? example: lst1=[1,2,3,4] lst2= lst1.append("new") print(lst2) Here, I want a new list without changing the earlier one ? In fact this applies to all the functions(eg: extend/append/reverse/pop/insert.......... Is there a way that the initial list remains untouched and we can make changes as per the requirement and store them in diff list/variables. I've seen this working in dataframes of 'R' language. Do we have an alternate here in Python

@bkirankumar4266 4 жыл бұрын

Hi Krish, I got answer for my question. The alternate was tuple. May not be exactly like dataframe in 'R', but serves as an alternate. Thanks Mate

Bro at last I can't understand index like where our digit placed could u please tell me

@tintintintin576 4 жыл бұрын

for example - d = [1,2,3,4,45,1,5,5,5,5] d.index(5,2,7) ------- compare with-------> d.index(value, start_index, stop_index) output = 6 It will simply scan that between the range (start n stop index) at which index the value is present. Output will be the index at which the value is present for the first time (first occurrence) in that particular range. 6 is answer because - d.index command will tell that between the start and stop range at which index the number 5 is present! hope this makes sense... happy learning..

@@krishnaik06 Dear Krish I think you should charge a minimal amount and with that money experiment with the animation or hiring graphic designer to make the brand look appealing as well. Content is top class, though it needs a little tweaking and presentation which needs money. A website will also be a great option, You have everything in you to deliver guest lectures in top universities. I am from IIT Roorkee and I guarantee you are better than the head of analytics we had. Good luck and God bless you.

I entered name= "Hello" but when i'm running print(name.isalnum()) it is giving me True as o/p. why??

@SridharD-wj9dx 9 ай бұрын

That is correct. Because, isalnum() function checks if all characters in the string are alphabets or all characters are numeric or a combination of both. If there is a space between words in string (e.g., 'Krish Naik'), it returns False, as space character is neither alpha nor numeric.
