Question

If I have for example x = 40 I want the following result:

40"

For x = 2.5 the result should be like…

2.5"

So I basically want to format to at most one decimal place. I currently use this:

"{0:0.1f}\"".format(x, 1)

But this displays always exactly one decimal place, which is not really what I want…

Answer 1

One option is something like

"{0}\"".format(str(round(x, 1) if x % 1 else int(x)))

which will display x as an integer if there’s no fractional part. There’s quite possibly a better way to go about this.
