You are not assigninground(h)to any variable. When you callround(h), it returns the integer number but does nothing else; you have to change that line for: h =round(h) to assign the new value toh. As @plowman said in the comments, Python'sround()doesn't work as one would normall...

For approximate-value numbers, the result depends on the C library. On many systems, this means that ROUND() uses the “round to nearest even” rule: A value with any fractional part is rounded to the nearest even integer. (对于近似值,则依赖于底层的C函数库,在很多系统中ROUND函数会使用“...
