You can use string formatting here:
"Je Body Mass Index is %.1f"%gewicht/lengte**2

The % inside the string says that one should format the thing
following the % after the string here. ".2f" specifies how it should
be formatted - f says that we will have a floating-point value, shown
in decimal (not exponentional form), and the .1 means that there
should be 1 digit after the decimal dot.
