numpy.argmin():该函数返回数组中某一轴的最小元素的索引(如果提到的话)。 示例: # import libraryimportnumpyasnp# create a numpy 1d-arrayarray=np.array([1,2,3,0,-1,-2])# find index of max element# in an arraymax_ele_index=np.argmax(array)# find max element in an arraymax_...

三维:方法一:arr3 = np.array([[[1,2,3],[4,5,6]]]) 方法二:arr7 = np.full((5, 6, 3), fill_value="ggg") (5行二维数组,每个二维数组里面是6行3列的1维数组) 关键点:[]的层数即是维度数 二.数据类型优先级:tr > float > int ...
1.使用np.array()创建 一维数据创建:,array的首个参数一定是一个序列,可以是元组也可以是列表。 1. 2. 如果一维数组不是一个规律的有序元素,而是人为的输入,就需要array()函数创建了。 In [8]: arr1 = np.array((1,20,13,28,22)) In [9]: arr1 ...
…and to compute the minimum value, we can apply the min function as illustrated in the following Python code:print(np.min(my_array)) # Get min of all array values # 1Example 2: Max & Min of Columns in NumPy ArrayExample 2 shows how to find the max and min values of a NumPy ...
