Module pyfmt 

Python number and string formatting corners that show up in console output: round(x, n), f"{x:.1f}", width padding by character count, s[:n] slicing, and html.escape.

Functions

commas

f"{n:,}" — thousands separators, sign kept in front.

fixed

f"{x:.{prec}f}", spelling infinities and NaN the way Python does.

head

s[:n] — the first n characters.

html_escape

html.escape(s) with quote=True.

pad_left

f"{s:>width}" — pad on the left to width characters.

pad_right

f"{s:<width}" — pad on the right to width characters.

round_to

round(x, ndigits): correctly rounded on the binary value, ties to even — the same digits CPython’s float.__round__ produces.
