[Python-Dev] f-strings

[Wagner Herculano]

Hi,
Thank you all for your time.
In fact I'm really a newbie and I need to study so hard (including English) to become someone like you all. I don't know if is possible, but I need to try.
Once again, thank you all for your time and I'm sorry if I'm bother both of you.

Kind regards,
       Wagner Herculano.

That's covered under "format specifiers" I think.
The PEP mentions this: https://www.python.org/dev/peps/pep-0498/#format-specifiers

I can see how a newbie might not realize that that means that f-strings use the same formatting language as the .format() method, and or where to find documentation for it.

So somewhere in the docs making that really clear, with a link to the formatting spec documentation would be good.

Not sure where though — a PEP is not designed to be user documentation.

That specific example is not mentioned in the docs, but there other examples of using format specifiers with f-strings.

Good evening,
I'm Wagner Herculano from Brazil.
I was trying to do a table exercise with number 5 and tried formatting spaces and did not find it in PEP 498 documentation.
Finally I found a way, if possible, include this example in the documentation please.

Below is my script with the desired formatting about table of 5.

n = 5
for i in range(1,11):
    print(f'{n} x {i:>2} = {n*i:>2}')

Result
5 x  1 =  5
5 x  2 = 10
5 x  3 = 15
5 x  4 = 20
5 x  5 = 25
5 x  6 = 30
5 x  7 = 35
5 x  8 = 40
5 x  9 = 45
5 x 10 = 50
-----------
Sorry my English, I needed to use Google Translate

Best Regards,
    Wagner Herculano
