[@AyushKumawat-j7n]

00:48:00 the string.capitalize() function changes ("this String") to ("This string") because it firstly converts all the characters to lower case and then just capitalize the first character. 00:52:30 you can remove duplicated by l=[1,2,2,1,9,4,5,7,4] print(list(set(l))) ## set() function changes the order of the list, use it carefully##

[@ironrose6]

To clarify, at least half of all these questions are about NumPy and Pandas, so don't waste your time on those if they aren't applicable to you. Also, 29 at 2:49:29 has needless complexity and you will get docked for it in most interviews. To quickly swap the first and last elements in a list in python it's extremely simple and easy and always the same: my_list[0], my_list[-1] = my_list[-1], my_list[0] Only build something more robust if they ask you to- don't risk wasting time and not being able to complete your interview.

For 2:04(Check if input number is pallindrome or not) I thought this is the simple program n=int(input("ENTER INTEGERS:")) b='' " for i in str(n): b+=i c=b[::-1] d=int(c) if d==n: print("The given number is pallindrome") else: print("The given number is NOT pallindrome")

[@bhargav7476]

Better code for palindrome 02:03:55 : x = 110011 if str(x) == str(x)[::-1]: print(True) else: print(False)

[@AMITKUMAR-np7el]

just write return str(x)==str(x)[::-1]

[@MrSyzygyG]

[@jyotibala7545]

i have got alot knowledge of python. fantastic. while watching this video, i enjoyed aswell as you kept on saying fantastic. it was awesome.

[@anandmathad5678]

When the concept is easy, like head and tail of a dataframe, he is explaining with examples.. But when he is explain complex concepts like merge, he is just walking through with explanation

[@deus9246]

Yeah! I also spotted that. I think he should fix that. Spending a lot of time on easy questions and just blushing on important questions is not that exciting.

[@anandkumar-ir8zj]

True , I've seen this clever move by many instructors

[@andyramananjanahary6739]

01:32:55 Actually, we don't need the dropna to remove the first the column. df=df[df.col1!=1] drops it

[@cassiehooo441]

Q29: 52:30 use my_list = set(list(my_list)) works. But the output shows the values in different orders as the original list.

[@vanihs8216]

Because set is an unordered collection of data

[@sage.swagat]

U can use sort() to when it is in list. mylist=[1,2,3,3] newlist= sort(list(set(mylist)))

[@Thewordmuse_]

1st Question) What are Key features Of Python) 4:27

[@marianomartinez84]

I'm just trying to do some constructive criticism here as this is viewed by a lot of beginners. IMO the example about passing values by value or by reference is misleading. In python, everything is passed by reference, except immutable objects which are passed by value. So in your first example where you are using a list and doing "print(arr)", the list is being passed by reference (actually a copy of the reference is passed). The print function could modify the list, it's just that it doesn't do it cause that's not its behavior. It would be better if you at least use a tuple instead of a list in that example, and better if you could talk about mutable and immutable types.

[@mohitkhushlani6733]

I agree with you, and I hope the instructor would have a better understanding of the python instead of just reading the already-made PPT/code/Content.

[@elahehsobhani4322]

Fantastic ! Thank you so much ! Just I realized that question 28 in the last part has not been solved correctly. If you try it with a string of length 20, and try to have 4 chunks, it will give you 5 chunks instead

Yes, the question says "into n chunks" but solution is doing chunks with number of n element.

for palindrome question. cant we write a function which returns the reverse of the number like def ispalindrome(s) return s[::,-1] s = 1221 p = ispalindrome(str(s)) if (p == s) print (' palindrome') else print('Not palindrome')

if condition will fail as s in an int while p is str

Question No 37 A tuple can contain only the predefined number of values, in dictionary there is no such limitation. A tuple can contain different values with different datatype while a dictionary can contain only one datatype value at a time

[@prashantmahamuni]

d = {1 : 'one', 2 : 2} , dict can heterogeneous datatypes

[@prathameshvaidya3508]

@@prashantmahamuni keys in dictionary are not heterogeneous dude

[@ironrose6]

@@prathameshvaidya3508 You didn't say dictionary key though, you said value. In dictionaries, a key is what references values. Make sure you don't get that mixed up in an interview.

[@csbytes137]

d = {1: "one", "one" : 1} is a valid dictionary, so dictionary keys can be heterogeneous. [version python 3.11]

Armstrong Definition is wrong! We can only cube each digit if the given number has only 3 digits. For other number we need to use power of total number of digits. This is the definition: An Armstrong number is a number that is equal to the sum of its own digits each raised to the power of the number of digits. so if your number is 3452 then we should check if (3**4)+(4**4)+(5**4)+(2**4)==3452. if yes, it is Armstrong otherwise not. similarly for number 10 we should check like this (1**2)+(0**2)==10. this not armstrong since 1 not equal to 10.
