Python中列表中浮点数的总和 [英] Sum of float numbers in a list in Python

问题描述

我在 s 中有浮点值:

p = list(swn.senti_synsets(a))
s = p[0].pos_score()
print(s)

# Output
0.0
0.0
1.0
0.0
0.25
0.25

然后我试了一下，print(sum(s))这给出了错误浮动"对象不是可迭代的.这该怎么做 ?

then I tried, print(sum(s)) which gives the error 'float' object is not Iterable. how to do this ?

解决办法:奇怪的是我自己找到了答案，我不知道，但是把一个单独的函数的东西放在一边.`

Solution: Strange that I found the answer myself, i dont know but putting the thing of a separate function worked. `

for x in token: 
sum_pos=sum_pos+posCheck(x) 
sum_neg=sum_neg+negCheck(x) 
def posCheck(a): 
p=list(swn.senti_synsets(a)) 
s = p[0].pos_score() return(s)`

def negCheck(a): p=list(swn.senti_synsets(a)) s = p[0].neg_score() return(s)

我无法总结列表，但是当我将函数放入 returntype 时，它​​返回了正数的总和.感谢大家的帮助.

I couldn't sum up the list, but when I put the function with returntype, it returned the sum of the positive numbers. Thanks to all of you for trying to help.

推荐答案

values = [0.0, 0.0, 1.0, 0.0, 0.25, 0.25]

print sum(values)

对我来说很好
