the "=" trick in the f-string is fire.

Ever since I learned f-strings...I love them.

This is the first time I have seen someone specify datatype for variables in python, and I honestly loved it. Great tips btw.

I've been using python for about 10 years, and f strings extensively, but never knew that last tip! Game changer!

About the fourth trick: the f in ".2f" tells it to format as float. You can also do for example ".2e"" which will format the number in scientific format.

The last one is super duper cool!

This kind of tips are awesone. We need more 👍

Great video! Didn't know about the datetime and debug print ones. Definitely going to use them in the future, though.

This is amazing!! thank you for this tutorial!!

Thank you for the instructive tips!

"Simple y bello como un anillo", como diría Neruda; pero además, muy funcional. ¡Muchas gracias!

Love your vids man! would love to see a tutorial on cython from you!

Nice collection! 💯

Great video! I missed the bonus tip where you explain that format string calls __format__ on the object being formatted, so you can do your own formatting, like this: class MyData: def __init__(self, a: int, b: int, c: int): self.a = a self.b = b self.c = c def __format__(self, spec): if spec[0] not in self.__dict__: sep = spec[0] l = list(spec[1:]) else: sep = ',' l = list(spec) return sep.join(str(self.__dict__[key]) for key in l) my_var = MyData(a=1, b=2, c=3) assert f"{my_var:cba}" == "3,2,1" assert f"{my_var:-abc}" == "1-2-3"

Didn't know about the date/time and equals formatting. Looks like the first one forwards to strftime. Makes things so much more concise and readable.

Absolutely fantastic and useful video!

Wow, so many simple things I didn't about... Thank you

So cool.. thanks for sharing it. very informative

Loved it ❤

Love #5. Thank you.

Loved the last trick!!!

Love the video I knew some of those but the last one is epic I will be using that from now on .

Very nice. Another useful is formatting float as percent: f"{foo:.2%}".

Great video.... Thanks a lot😍👍

Great work sir❤

F strings are soo chef kiss

Thank you, this went STRAIGHT into my current project. Commas in numbers was one of the next things I was going to look up.

Great video. Thanks

Great video!

Finaly! All fstring variations in one film

Nice and useful tricks for every day programming. I also prefer specifying types of variables, since it makes code better understandable.

thanks for the showcases

i love f strings also this is like the 3rd time i come across the = specifier but i keep forgetting its existence and type in the whole thing

That last one is sooo useful!

Thank for nice tricks 😘

Very nice Thanks

Thanks very much

Last trick was super cool...

This is pure gold 🥇

thanks for your time please make videos about data structure

The last one was good!

This is super cool, I sadly can't think of any usecases in my current project

Круто! Спасибо!

Nice Tricks!

Does datetime have a formating depending on nation? Like we would have already through a login or a whois access to a users current or defined whereabouts or nationality and we would want to have their specific way of reading time provided for them.

For those who didn't know, the last one is called self-documenting expression and was released in Python 3.8

Very nice.

Yep, I'm saving this video

nice examples

Thank you

the last fstring was dope

I like that print(f’{a + b = }’) one at the end. I can think of a few times when I’d use that.

Trick #2 is neat

Klasse 😃👍

i knew last one already, but seeing it again made me realise i should try to do this in java too, would have shortened a whole lot of cruft in one program i made.

ooh i like these videos logic magic !

What can you do with print(f'{var: >+{x}}') ? The additional + get's printed in front of var but a - doesn't, you can put a # instead of the + and it's not throwing an error, yet doesn't seem to do anything. Letters and other symbols give an error.

Hello @Indently, Can you please explain me, why you use ":" after a variable for ex. n:? Regards.

Good Job

These will be useful to me for sure. Here's a comment for the algorithm gods!

That last one goes wild

9:30 that approach though had the single quotation marks removed, which from a formating pov is cleaner, isn't there a version of the first shorter approach without the quotation marks then printed? (edit: while still being flexible in terms of variable names as mentioned)

Superb

I always use pyformat. Very easy to understand and pretty nice too. Var = 15 print(“this is my var: {}”.format(var))

thanks

Awesome! I love the '=' and >

May I ask which IDE and development env are you using? Looks so great

Which editor is that? Looks fresh

You're cool! 👍

Useful. Thanks

The last one blew my mind

what theme do you use pycharm

Which code editor do you use? It appears to be pycharm. But the ui is different from what I have in windows laptop.

rounding in python .. cool

Gold!

I was so stoked when f'{ var = }' was added to Python!! Might be abusing it a bit lol

what complier/interpreter does he use?

Hi! Thanks! Great video! Worth mentioning that the last one does not work on older versions of python3 (I tried it on 3.7.17 and it gives a syntax error).

My preference is th .format(...) method fo a couple o reasons. I use Micropython a lot and f""" is not or has not been available, for format supports all the styles I like. i8n the string being formatted is not known at development time. Scope, the names using inside the string can be assigned at use time, i.e. in a function the value may be in a variable gmt_time but the string uses a standard name 'time'.

To use scientific notation with integers, you can either do int(2e9) or 2*10**9.

big fan bro from india

i dont really know anything about programming or python but im curious. when you do "var:" is the colon part of the variable name? or a requirement for specifying a variable name? if its part of its name, is it to differentiate it from something else?

This definitely seems more convenient than it is in js.

Intersting, a large part of the world is using . (period) as a 1000 separator and , (comma) as a decimal point.

My professor who I took intro to Python called the “” ‘right justify and left justify’

the thumbnail to this video inspired an idea to use format strings in dictionaries so that a dynamic series of texts can undergo a linear list of mutations. Honestly, I actually need to refine my idea though.

What editor is this?

You make the code easier to read, so you better use the functions of the str class! 🐳

Hi, if I have a number 1234.5678, how do I use a combination of , separators make it 2 decimal places so I get 1,234.56?

This Video was sponsored by me. 💀

Ehem yo bro, are the "int" word after name variable is static type like variable declaring in rust "let num : i32 = 1000000000"?

In the first example, int variable n assigned a number in scientific notation returns a float number when printed, but no error occurred. In what sense must n be declared a float therefore?

in the first example, do you know what decimal points wouldn't work?

3:24 this tip will literally improve my code quality

i'm old but i still think everyone should know that most of the f-string stuff comes from C printf/strftime/etc.

What does the f prefix do at the beginning of the argument? Are we inserting a blank float?

Fact: You can define custom logic for f'string on your classes and get string after : as argument to __format__

What IDE are you using? It looks like VSCode but seems like not

Apart from learning about the f condition, I also learned you can declare the data type in python which i have not been doing lol

Don't forget in newer python you can add multiple lines of text by stringing together f strings
