The = Can be uset to print both variable names and their value. print(f"{foo=} {bar=}") - will print “foo= 1 bar= 2”. Useful for quick debugging.

[@Indently]

I immediately realised after I uploaded the video that I missed that one

[@Martin-delta]

@@Indently I even think I learned it from one of your previous videos. :)

[@schlopping]

Correction: Not variable name, but expressions! e.g. f"{1+1=}" -> "1+1=2"

[@tuzaguilar4201]

Thanks! I was looking for something like this just a day ago.

[@FreihEitner]

This is VERY cool and handy info. I'm fairly new to coding in Python but I can already see some users for this.

[@cirklare]

That's why you need to read the manual for anything you buy

[@Indently]

I'm the kind of guy who buys the Lego™ Death Star, throws away the box, and builds something entirely unrelated.

[@Chalisque]

Something I like, when defining your own classes, is that whatever you write after the : (e.g. the 'turnip' in {a:turnip}) gets send to the object's __format__(self,formatstring) method. So it's very open-ended.

[@grzegorzryznar5101]

1. Reduce amount of decimals is not the best word in that case, cause the number will be just rounded not cut off ;) 2. Recently, I've discovered, that it is possible to add own format to class via __format__ magic method ;) And then it can be used in fstring for example

Thank you for this video, it is very helpful

[@GamingAbroad90]

i saw these a couple weeks ago, but i didn't know about the last one

[@532hariharareddyg5]

best explanation

[@EvokerKing]

6:55 could you show us in a separate video how you can make the part set up to handle that in a module similar to the way the datetime module handles it? i know it uses some kind of format function, but that is it.

[@ChronicoOne]

As someone who's written a function in Python to properly print out a date, I am grateful for your enlightenment. If you want to be enlightened about machine learning, tap my face😅

[@manarmimi3073]

Thank you Good job.

[@emadelazhary2373]

Thanks.

[@bernardcrnkovic3769]

i dont know why i laughed so hard at the start..

[@richardboreiko]

Can you indicate AM or PM with the time?

[@ayushpurohit8266]

Yes

[@trp]

This is so cool

[@benfurstenwerth]

datetime.datetime.datetime lol made my morning! Thank you for that

[@Heavy_Lvy]

How did you causally do the start of the video

[@Lanxxe]

Is it possible to make a space " " the thousand separator with f-strings ?

[@Martin-delta]

{:,d} is not locale aware. So the simplest way is just .replace(',', ' ') Or you can use the locale lib and override the default separator. import locale locale.resetlocale() # Load default locale locale._override_localeconv = {'thousands_sep': ' '} # Set space as thousand sep locale.format_string('%d', 123456789, grouping=True) => 123 456 789

[@-awwolf-]

Is there a way to swap points and commas in floats, as it is written in Germany, for example?

[@Indently]

Unfortunately, I don't know of any way of doing that with the simple {var:,} syntax, which is really annoying.

[@yibing8112]

watch video before: proficientin in python after: heard python

[@ruzibayevich1693]

I didn't feel how I lost my 9 mins , I didn't wanna watch it till the end actually 😂

[@zapp7746]

F strings are cool but Zapp's comments are cooler

[@howl2339]

Bananas, mhhhhh

[@Mulakulu]

Im still disappointed that we can't use a variable in place of that 20 for spacing

[@Indently]

Yes you can, watch the entire video and you'll see how.

[@Mulakulu]

@@Indently oh shoot. I'm spreading fake news. Thank you 👍

[@nugget7236]

Today I learned that a scientific notation is not a error

[@Indently]

😂

[@Lahmeinthehouse]

How is this useful?

[@Indently]

What do you mean?

[@Lahmeinthehouse]

@@Indently why would it be interesting to print something with a lot of spaces and characters? I just don’t see the value in it in general

[@Indently]

Formatting is a preference. You might want to make some logs look nice to make it easier for a user (or even yourself) to understand.

[@Lahmeinthehouse]

@@Indently oh, right! Good point, thank you ☺️

[@sg8nj]

print('{:*^10}'.format('Hi')) try this. Output: ****Hi****
