#数字列表中 连续最大的和 #单次循环，主要是计算思想 maxAddNum =0 loop = 0 testList = [-1,2,3,-4,5,-6,7,8,9,-10] for i in testList:     loop = loop+i     if loop>=0:         maxAddNum = max(maxAddNum, loop)     else:         loop=0 print(maxAddNum) #多次循环遍历，比较每种遍历的结果

maxList=[] for i in range(len(testList)):     maxNum = 0     for j in range(i,len(testList)):         maxNum=maxNum+testList[j]         maxList.append(maxNum) print(maxList) print(max(maxList))
