I feel like the most useful case where you'd use strip() was left out of this video. When used with no parameters, it strips spaces from the beginning and the end of a string. It's used all the time as the first step in sanitizing data from user input. I loved this video regardless though! I did not know about some of these, namely the weird fill ones
Also the difference between strip and removeprefix: the first one takes a list of characters that may be removed multiple times, while the second one just removes the parameter as a single string.
.format() should only be considered for legacy code. F-strings are far superior and should be chosen in every case they can be used… much like List Comprehensions should be chosen wherever possible.
One of the greatest videos about python strings I have watched on TH-cam. It is comprehensive! One thing I want to add is the difference between lstrip and removeprefix. The first one removes all the characters specified in its arguments starting from the left of the string until it faces a character that is not in the list of characters specified in its argument. So, print(‘Luigi gui guard’.lstrip(‘Luig ‘)) will print “ard” The second one removes the substring passed to it. So, print(‘Luigi gui guard’.removeprefix(‘Luigi ‘)) will print “gui guard” The same thing apply for rstrip and removesuffix I enjoy watching your videos. Keep the great work!
I typed out every string method as I followed this video! omg we did it! Thank you for such a valuable video!! viewer: str = "{subject} is: {action}." print(viewer.format(subject="Midnight Anna", action="subscribing!"))
The lstrip() was presented here very shortly and used only in one scenario. It is important to add that if the text was "someemos text", it would return " text". If you want to remove only the "some" from "someemos text", you can use removeprefix(). Be careful with this. Last thing someone mentioned it in comments was: "What if you didn't give it any parameters?" -> It would delete spaces only on the left side, if there had been some spaces ofc
one thing that makes sense for learning is to logically group operations together, like print(text.center(20,'*')) print(text.ljust(20,'*')) print(text.rjust(20,'*')) 3 alignments that take the exact same parameters. also, isspace() counts ALL whitespace as spaces - so tabs and linefeeds count as well, more useful than testing only for the space character.
yea, it's a bit misleading, since afaik python doesn't specifically have single characters and all these functions work with strings .replace() .startswith .endswith() etc
I enjoy these types of videos. I've used Python for years now but find myself using methods I'm more familiar with, and making them work instead of using the correct method and saving time. Keep up the great work!
I think it's worth mentioning that neither isdecimal() nor isnumeric() nor isdigit() return True for a line '-1', regardles the line is perfectly fine for int().
Wazzaaap, even though the index was my best one for some personal reasons , I found both center and expandtabs very useful in my current project, thanks to you as always, and happy new year!
Hi there, Great topic for strings, but if I want run the code in start of video it is not working code is as follow: def get_string_methods(): i: int = 0 for method in dir(str): if not in method: i += 1 print(i) print(i ,method, sep=': ') Is there any thing missing in the code?
Disregard, despite the internet not having anything, ChatGPT gave some good use cases for normalizing strings before tokenizing and feeding it into NLP models and such.
\v \u \b ... in one function call, returns False if found any of them. can not test just on "\\" or chr(92) in text which could be normal. no need for if "\t" in text or " " in text or " " in text .... :
@@Indently Ahh I didn't see the count before. After watching the video though, I thought would it be better to do if not method.startswith("__") instead of if not "__" in method as it would allow functions to have a __ inside of them, as well as not checking the whole string for the characters
@@Indently Here ya go. Thanks for the video. def print_methods(obj): methods = [m for m in dir(obj) if '_' not in m] for i, method in enumerate(methods): print(i + 1, method, sep=": ")
Can you be more specific? Because you can directly type -> 🔥 for example and it will be in your code.
2 ปีที่แล้ว
@@Indently Specific? So, I dont know how to do it. You use at 13:49 some emoji as some character of string. But how I can type it? Its need for that some addon with browsing allowed emoji or what? You write "you can directly type" but how to directly type emoji of fire on keyboard?
Now I understand what you mean. On Mac I can do it by using a shortcut which gives me a small emoji table. You would have to search on Google whether there's an option for quick emoji insertion for your OS.

Lol, I never knew that! I always just use split() with join haha

@@StampleD2147AI Using split() and join() is still useful when trying to remove multiple whitespaces between words.
And also removes new line character (
), thats handy when reading from a file.
Honestly, the format method deserves a video on it's own.
And f-string as well....
.format() should only be considered for legacy code. F-strings are far superior and should be chosen in every case they can be used… much like List Comprehensions should be chosen wherever possible.

1. For isalnum() also "_" is valid
2. ascii is pronounced as "aski"
"_" isnt valid for isalnum() just checked 😊

on the endswith() you can also use another string not a single char, i.e. “apple”.endswith(“ple”)
yea, it's a bit misleading, since afaik python doesn't specifically have single characters and all these functions work with strings
.replace() .startswith .endswith() etc
This really helped me get an understanding of writing code on the basic level and complete problem sets. Thank you brother👍

I’m the same, finding ideas like this to record is what I really enjoy doing, and even better if they help people :)
Thanks for getting straight to the point with every form sir 🎉❤
Love this video series - I'm documenting every single bit of them in my IDE as reference material
As usual, I learned something new from this video! It's a really useful summary!
Bruv , Make a cheat sheet for all 47 methods . You have covered everything . We need to have a cheat-sheet with examples handy.
I think it's worth mentioning that neither isdecimal() nor isnumeric() nor isdigit() return True for a line '-1', regardles the line is perfectly fine for int().
brother this is the best video when i seen, short but all methods understandable
Great Vid! I'm learning Data Analytics rn using Python. Your content is helping me out. Thank you!
This was very consice and easy to follow; thank you for the time stamps.
5:15 in python 3.6 and later, often f-strings are cleaner than .format()
Love this, really nice refresher, and some that I was not aware of. Thank you.
i think this is the most useful video i've seen today thanks for your effort 😍

Thanks for the nice and helpful info.💚
wow bro thanks greets from Uzbekistan🙌👍
Great video. Mot likely I'll have to come back eventually hahaha I really like your channel.
8:21 these are actually Chinese digis btw
A must-have video for beginners. thanks
Great explanation and very useful
Love videos like this. Thanks for sharing!
its been a year! and still a wonderful video :)
What's the difference between casefold() and lower()?
casefold is more aggresive than lower -> example with german ß, casefold will make it ss but lower wont do anything
@@dzendys_ Thank you for the quick response :).
thank you for making this video!
TH-cam says that two videos in the playlist are hidden - can you tell us what they are or unhide them?
thanks for sharing man, good explanation
Thanks a lot :)
You are the best. Everything is well explained
🤩
this is so good, Thx for that
thank you for all explanations
You are superb ma bro ❤ i really understand your explanation
Thanks for the knowledge...................... it's just insane lecture
my brother in Christ that’s mandarin. Great vid btw 9:17
Thank you bro, im making sure im all refreshed for my final tomorrow lol
Thank you very much, your are a gift!!!
print('Interesting and helpful!)
Very interesting and usefull ! Thanks
pretty useful videos, just in case, #17 are CHINESE NUMBERS!!
Hi, could you make a video on functions of python from basic to advanced, and nested functions and class methods nested functions
Very useful. Thanks 👍
Thank you, this video is very informative.
I didn't know there was an "isAshi()" method 🤣🤣🤣 (7:05)
Me neither, I never heard "ASCII" pronounced that way... ;-)
Very very good lecture
Amazing content ty
I ❤ your videos! Good job
Very useful thank you sir❤
Thanks for sharing, Big help!
BTW, 8:30 those are Chinese numbers! hahhah
Thank you very much sir.
I LOVE YOU!☺
Looking for some DATABASE functions like CRUD!!!
great video .
do more method vidoes
Would be cool to do the same with DICTs and LISTs. Many thanks!
Creating a function to run desired string function against each item on the list should solve this
8:28 they are Chinese btw *
0:52 xDD i saw that
Why do we need to use translate/maketrans? The replace method is really easier!
Hellooo, 15:32 Guys. I loove this video

rely very useful 😍😍
What your IDE you use?
I don't like to use "format()", just ues f-string, it's mort ez to understand and read
Can someone give a use case where .isprintable() would be important? I'm sure it is useful, but I can't think of anything.
Disregard, despite the internet not having anything, ChatGPT gave some good use cases for normalizing strings before tokenizing and feeding it into NLP models and such.
detects \t
\v \u \b ... in one function call, returns False if found any of them.
can not test just on "\\" or chr(92) in text which could be normal.
no need for
if "\t" in text or "
" in text or "
" in text .... :
Hey is it just me or is VS Code faster in code suggestions eg AI
Why exactly does .format_map(dict) exist? Couldn't you just do .format(**dict)?
good one
I remembered to comment. Was that wazzzaaap speedy?
can you make a finger counting app
Is casefold different from lower in any way?
Yes
Lower only lowers english words
Casefold takes every case and lowers it
Like β is ss
At least I think it's like that
which compiler u using?
Probably CPython
Note guys these methods do not alter the actual data that variable is constant...
I learn something new
Hello . Thanks
Gracias
THANKS
No problem
You could've used enumerate in the loop at the start!!
The count would not display properly with the code above because of the if check. But you're welcome to share some code and show me otherwise :)

if not method.startswith("__")
