I am a beginner and you caught my interest. Now I really want to learn more.
i started learning python from your videos please don't stop uploading videos please upload All Concepts till the end..your doing great job..one day your helping Brings Lot of Happiness to your life..
ok
Very helpful videos... I successfully tried many examples with different alternatives. These videos developed my interest in learning data science . Thanks a lot.
Thankyou for making these videos on Python and data science that are immensely helpful as a guide to learn this vast subject.
You explained everything so clearly . Thanks for your effort sir
i was able get many methods of string and list in single video thanks a lot
Hey I understand Indian accent. Thanks for course. It is the one of best channels of data science in CZcams
Nice lectures Krish..Easy to understand..Thank you
Best way to explain concepts 💯
Krish Garu - You are doing great job.
Thanks! enjoyed and learnt with this.
It was really helpful.. Would like to learn about R programming too...
Your explanation is very very nice
Sir i was going through your videos to learn python but i found that code with harry is good to start...bcs his way his pace his language works like smooth bridge to connect new student and concept
Wow...you are too good..thanks
thank you sir, it is usefull for me and previous also
best tutorial on python
Hi sir I like the class you take. Sir i wan to become a ai engineer soon by learning your videos even i will join ur channel sir.
great amazing explanation
Thanks Sir😊👍
done...heading to video number 6 :)
krish bhaiya ur so good.
Thank you sir. 😊
You're awesome dude.
Thanks Krish
you are amazing sir
Thanks
Done !! and Implemented
nice video,useful
thanks sir!!
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
You wrote append instead of index. Anyways thanks for sharing!!
@@debayanmazumdar3056 Corrected it. Thanks.
thanks
Your name starts with "K" & ends with "K", because you are the "King"😍 #much_love #from_Bangladesh
easy and wise teachings thanks sir. hopefully you will tell me that if Mac m1 is suitable for data science I have installed anaconda as u told in your intro video thanks gbu
Hi sir, your voice is up and down, kindly check it.
hi krish naik, at 4:57, it says isalnum #check if all char is num, ##not just num it check for num and alphabet too, i like your course, thanks for uploading, i liked shared and subscribed to show my support.
This comment should be pinned
Krish, can you suggest me a playlist or set of tutorials to learn Python, if a person is familiar with R and has learnt R programming recently.
Sir can I know per day how many videos u will upload on this course ?
Hi sir thanks a ton for uploading such easy to understand videos..
Sir i have an outdated computer, so i was looking to buy a new laptop or a pc in a week..
So pls suggest me which might be the best configuration so that i could use it for machine learning
16gb ram 1TB of hard disk along with 256 gb of SSD and a minimum of 1050 NVIDIA graphics would do in order to learn machine learning.
Sir, In the Machine Learning Playlist the tutorial 14 is missing. Can you tell me what is in the tutorial 14?
Completed on 30/6/24
thank krish btw do you mind to teach us how to use altair?
Hello Krish, what are the best machine learning books, material can I refer please let me know. Thank you
Hi I have started python from your videos ...small doubt the exercise file you told that will get in gethub is not available. Can you guide me where to get it from
Could you please share the .ipynb files after end of each lecture
Hello Krish,.
Do you teach students ? I'd love to learn from you.
Hello Krish Naik thanks for your videos.
My question is why 'instant creations' is showing true while check for isalnum. iPython showing TRUE.
I have few items in list1. I ran len(list1), I am getting 'builtin_function_or_method' object is not subscriptable error. What could be the reason?
At 4:15, it is giving false due to whitespace not because it does not have numbers.
happy teachers day :)
Hello Krish Naik Sir, I started learning python course, I am a graduation B.com background, So after I will complete the courses and I will apply for the job, Companies will acceptable for the opportunity. Why because I am not a b-tech or engineering background. It is possible to learn python?
Sir in bollean variable I'm not able to open the option of functions even after pressing tab
At 4:14 isalnum() is giving False due to the space character in the string as it is not alphanumeric
Correct. If you get rid of the space, the value turns to true
yes
Krish bro one thing you forgot , I am waiting for kaggle competition House price prediction feature selection and improve our accuracy please upload that , I am curious see how rank gets below 100
Still working on it brother
Please upload that one
8:07 for my example, I used the same as above, but getting False, why so?
thank you for video
lst_=({1,2,4,34,5})
why not it is dic?sir
Hello sir, when you will start your course at UDEMY
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
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
Krish, your voice is going low/off very often. Please check this issue for your future videos
hello krish sir, please tell me how to function definition in google colab?
Hi Krish, I am unable to open the file (2-Python List,Dictionary,Sets etc.ipynb) downloaded from github. The following error comes up Unreadable Notebook NotJSONError("Notebook does not appear to be JSON: '\

sir please provide notes of these all lectures...without it is difficuilt to do...
sir i am not getting those options if i press tab
Maybe there is some problem with mic the voice is glitching..... Very good video easy and simple... You teach well.... Please check for the issue though. Also stop saying "basically" too much 🤣.
;) yes trying hard
.isaplha() -> Checks if all characters are alphabets and numeric
IDK why but I'm getting really different values when I use the operation.
Completed 27 June 2023
Do we have any notes for python?
Is this playlist is inorder?
How to check index of a specific item
sir my name is Anuj I am first year student do i learn python ? coz I don't have enough knowledge in programming Lang like c or c++
Why i am getting list item is not callable error
Please make a videos on artificial intelligence complete course
Bro at last I can't understand index like where our digit placed could u please tell me
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..
sir, when i am writing any one sentence under colon and using isalnum() function it is showing output true but sir i have written only string under colon and one more thing sir when i write two sentence in a colon like "priyanshu go" it is giving output false how it is possible sir ?
Please, remove the space, space is neither alphabet or numerical.
Hi Krish,
Can you let me know where can I practice Python online?
on datacamp
at 4:28 he is getting false because of the space in between his name otherwise .isalnum can give true when there is only alphabet or only number
I entered name= "Hello"
but when i'm running print(name.isalnum()) it is giving me True as o/p. why??
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.
sir aapne jo ye python ka course karwaya hai unke pdf mil jayenge
Getting error
lst=list ()
List object is not callable
When i press tab after typing "my_str." i do not get the list of functions. Should I turn on this feature somewhere?
try shift + tab
Mine is also the Same problem
I tried to press shift +tab though it not coming optiona
Hi Im a beginner in Python. I am getting below error please help
name 'my_str' is not defined
execute my_str also using shift+enter.....then
Weren't you supposed to charge for the full course ? Or is that a different one
I am making python free for everyone
@@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.
Bhai looping ke lec kaha hai ?
Input : Krish_Naik.count(basically)
Output : Infinity
😂😂
at 5:41, I am using my name "without numbers" just my name yet it returned ALphaNum as "true"
Why is that Krish?
Day 1- 16/02/2024
Now?
lst=list()
Above code snippet giving the following error
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
in
----> 1 lst=list()
TypeError: 'list' object is not callable
Any help will be appreciated.
Check whether u have created a variable list. If yes restart the kernel an d execute once again
lst=list()
This is not working....
bhai is me add bhot areee h ????
