1. Sum of All the Elements in the Array If we pass only the array in the sum() function, it’s flattened and the sum of all the elements is returned. Output: 2. Sum of Array Elements Along the Axis If we specify the axis value, the sum of elements along that axis is returned. ...
生成随机整数数组:使用numpy的random模块中的函数生成随机整数数组,并设置生成的整数范围为[1, fixed_sum]。 代码语言:txt 复制 random_array = np.random.randint(1, fixed_sum, size=num_elements) 调整数组使其满足固定的sum值:由于生成的随机整数数组的和可能不等于固定的sum值,需要对数组进行调整...

是先int 再 sum 所以结果是1 相当于[0,0,0,1]
The numpy.sum() function is available in the NumPy package of Python. This function is used to compute the sum of all elements, the sum of each row, and the sum of each column of a given array.Essentially, this sum ups the elements of an array, takes the elements within a ndarray,...
NumPy provides another function ‘cumsum()’, the function takes in an array and at each index gives out a cumulative sum after adding up all the elements of the lower indexes of the array. #importing the NumPy library importnumpyasnp ...
