根据Python中键匹配的条件对字典中的值求和

Question

给定字典:

dic = {1: 45, 2: 4, 3: 56, 4: 667, 5: 90}

如果对应的键值大于或等于某个阈值(例如3)，我想将这些值相加，然后将总和除以一个数字(例如100)

我试了如下:

threshold = 3
num_to_be_divided = 100
s = sum(v for v in dic.values() if dic.keys() > threshold)
prob = s / num_to_be_divided

Answer 1

根据Python中键匹配的条件对字典中的值求和

dic = {1: 45, 2: 4, 3: 56, 4: 667, 5: 90}
X = 3
_sum = sum(v for k,v in dic.items() if k >X)
print(_sum/100)

Answer 2

try this:

print(sum(value for key, value in dic.items() if key >= threshold) / num_to_be_divided)
