【问题描述】:
进一步不是正确的代码。 如何让它正确、简短、美观?
def normalize_weights(weights, threshold=0.01):
total = sum(weights)
result = [x / total for x in weights]
result = [int((1.0 / threshold) * x) * threshold for x in result]
result[-1] = 1.0 - sum(result[:-1])
print(result)
result[-1] = int((1.0 / threshold) * result[-1]) * threshold
print(result)
normalize_weights([1.0, 1.0, 1.0])
[0.33, 0.33, 0.33999999999999997]
[0.33, 0.33, 0.34] # ok
normalize_weights([1.0, 3.0, 1.0])
[0.2, 0.6, 0.19999999999999996]
[0.2, 0.6, 0.19] # wrong
提前致谢
编辑:结果的总和应该等于 1.0
【问题讨论】:
-
第二次调用函数的期望输出是什么?
-
[0.2,0.6,0.2] 结果的总和应该等于 1.0。
