the explaination be like : IT IS SO BEAUTIFUL, SO ELEGANT, JUST LOOKING LIKE A WOW

[Astitva]

This video is a tutorial about string manipulation in Python, covering various operators, functions, and methods applicable to strings [00:00].

Here's a breakdown:

String Basics: The video begins by recapping the definition of a string as a sequence of characters, emphasizing their immutability and how individual characters can be accessed using indexing in both forward and backward directions [00:20].
Traversing Strings: It explains how to access each character in a string one by one using loops, including examples with membership operators and the range function [01:27].
String Operators: The video details various operators that can be used with strings:
Concatenation (+) to combine strings [04:10]
Replication (*) to repeat strings [05:21]
Membership (in, not in) to check for substrings [06:34]
Comparison operators (==, !=, >, <, >=, <=) which compare strings based on the Unicode values of their characters [08:30]
String Slicing: The concept of extracting parts of a string using slicing is introduced, explaining the use of start, stop, and step parameters [11:57].
String Functions and Methods: The bulk of the video is dedicated to explaining various built-in string functions and methods with examples:
len() to determine the length of a string [17:12]
capitalize() to convert the first character to uppercase [18:05]
count() to count occurrences of a substring [19:34]
find() and index() to locate substrings [21:23], [23:07]
Methods like isalnum(), isalpha(), isdigit(), islower(), isupper(), and isspace() for validating string content [24:32], [26:03], [26:55], [27:49], [29:46], [28:48]
lower() and upper() to change the case of a string [30:40], [31:19]
lstrip(), rstrip(), and strip() to remove whitespace [32:04]
startswith() and endswith() to check for prefixes and suffixes [34:15]
title() and istitle() for title casing [36:03], [37:09]
replace() to substitute substrings [38:05]
join() to concatenate strings from a sequence [39:11]
split() and partition() to divide strings [40:57], [42:47]
Practical Implementation: The video concludes with a demonstration of how to use these methods in Python programs, including examples for counting uppercase/lowercase characters, digits, symbols, words, checking if a string is a palindrome, and more [45:36].

I was so exasperated by all the recommended explanation videos being taught in hindi even if they do the explanation is not good
I finally found a perfect channel with simple yet clear explanation 🥲thank you so much ma'am
I don't usually comment but i felt the need to appreciate your effort🙂. I will definitely share your videos and i hope you get a million or more subs in the future💪✨✨

[RidhaneshMaara-ebvd]

Your teaching is superb mam
Last minute stategy for today's test

[AnnaSingh-gi]

Life saver video for last minute preparations. Loved it 💗📝

[masterpradeesh]

once again thank you mam every useful for my exam. GOD BLESS YOU

[AbiniveshAcademicCreations]

Mam, you do well, but there's a problem using the notes, please check on it, we get invalid URL in the description

[himanshisharma]

This vedio is soo helpful for meee thanku mam ❤️

[PushpendraKumar-xrwk]

Thank you for this great explanation ❤

[Pro_Ghost_Commando]

How many years of teaching experience?

[PushpendraKumar-xrwk]

Please mam provide the notes of this lecture

[batmanserious]

maam when i try to download notes it says file doesn't exist

[melbinbiju]

very nice and well explained class. Thanks very much maam

[Nike-whey]

mam which software you used in the end

[hanu.]

Well explained, you are for sure the best CS teacher ❤️ Thank you so much mam for this wonderful video.

[jayasriP]

Thankyou for this amazing class😊

Mam, there's a mistake in the topic comparison operator. The function that returns character corresponding to ordinal value is chr() but you have written char().

[sanjanaclive]

Mam it would be helpful if you show us more examples for each topic in such a way we understand them better through different types of examples.

[BimlaJoshi-nq]

Really mam your explanation is so nice everything is clear after watching this lecture thank you so much mam😊
tomorrow is my computer science exam and I hope I Will Score good marks after watching your videos....❤

[Tanitya]

so mam what will be the difference b/w title() and capitalize()

[sohamshukla]

Ma'am your english is very fluent I understood everything in a very pleasant manner.
