round(x) will round it and change it to integer. 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. ...

"values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done toward the even choice." 如果距离两边一样远,会保留到偶数的一边。比如round(0.5)和round(-0.5)都会保留到0,而round(1.5)会保留到2。 Python 2.7 中的结果如下: ...
