此外,这不是正确的代码。 如何使它正确,简短和美丽
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
提前谢谢
编辑:结果之和应等于1.0
也许吧
如果你想有两个小数位并强制
1.0
