What does !r:<3 mean?

Question

I was following a tutorial and found this.

print(f"{self.name}: {card!r:<3}  ", end="")

And I have no idea what the !r:<3 means. Google wouldn't give me relevant results because of all the symbols.

See https://docs.python.org/3/library/string.html#formatstrings — mkrieger1, Mar 02 '21 at 16:57
Does this answer your question? [In Python format (f-string) strings, what does !r mean?](https://stackoverflow.com/questions/44800801/in-python-format-f-string-strings-what-does-r-mean) — Carcigenicate, Mar 02 '21 at 16:57
Doesn't seem to be great in this case, but in general: http://symbolhound.com/ — Manuel, Mar 02 '21 at 17:00

You can find a description of the format of f-strings here and of the formatting language here.

!r:<3 uses repr to format the value, left aligned with a minimum width of 3 (padded with spaces by default).
