Question

I’ve been searching for a way in python to get only 4 digits on the right of the comma of a decimal number, but i couldn’t find. Took a look on this post,—> Rounding decimals with new Python format function
,but the function written there…

    >>> n = 4
    >>> p = math.pi
    >>> '{0:.{1}f}'.format(p, n)
    '3.1416'

…seems not to work in my case.

I imported the modules “math” and “decimal”, but maybe i’m missing some others to import, but i don’t know which of them to import.

Thanks everyone, and sorry if this issue has already been posted.

Answer 1

"%.3f" % math.pi

I know its using the old syntax but I personally prefer it.
