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 RU-vid. 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.
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 .... :
@@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.

@@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.

@@Indently So simply copy from somewhere and paste into code ? Ok, its seem easy. Btw thx for this video and video called "6 CLEAN Tips To IMPROVE Your Python Functions" , I learned a lot today. I subscribe you today.
