Python:TypeError:无法解压不可迭代的 int 对象

code for finding the large sum in the array:

def maxsum(arry):
    if len(arry)==0:
        return 0
    summ,maximum_sum=0
    for i in arry:
        summ=summ+i
        maximum_sum=max(summ,maximum_sum)
    return maximum_sum    
maxsum([1,2,-1,-2])

得到以下错误:TypeError

Traceback (most recent call last)
<ipython-input-5-59dc92538282> in <module>
      7         maximum_sum=max(summ,maximum_sum)
      8     return maximum_sum
----> 9 maxsum([1,2,-1,-2])
     10 

<ipython-input-5-59dc92538282> in maxsum(arry)
      2     if len(arry)==0:
      3         return 0
----> 4     summ,maximum_sum=0
      5     for i in arry:
      6         summ=summ+i

TypeError: cannot unpack non-iterable int object

解决方案

变量赋值错误.

def maxsum(arry):
if len(arry)==0:
    return 0
summ,maximum_sum=0,0 # Changes
for i in arry:
    summ=summ+i
    maximum_sum=max(summ,maximum_sum)
return maximum_sum
