"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: ...

This has unexpected behavior in Python 3 and it will not work for all floats. Consider the example you gave, round(123.455, 2) yields the value 123.45. This is not expected behavior because the closest even multiple of 10^-2 is 123.46, not 123.45! To understand this, you ha...
