import numpy as np a = np.array([3, 1, 2, 4, 6, 1]) print(np.argmax(a)) 当没有指定axis的时候,默认是0.所以最后输出的是4(也就是表示第四维值最大) 2.二维数组 import numpy as np a = np.array([[1, 5, 4, 2], [9, 6, 2, 8], [3, 7, 9, 1]]) print(np.argmax(...
1. Python max() function max()该功能用于– 计算在其参数中传递的最大值。 如果字符串作为参数传递,则在字典上的最大值。 1.1. Find largest integer in array >>> nums = [1, 8, 2, 23, 7, -4, 18, 23, 42, 37, 2] >>> max( nums ) 42 #Max value in array ...

When compared to the other programming languages, a Python list is essentially a simple array. Elements are indexed based on their position in the list and there can be multiple elements with the same value. The main difference is that lists in Python cancontain elements of different types. Th...
一、python内置函数 abs() 求绝对值 例子 all() 把序列中每一个元素做布尔运算,如果全部都是true,就返回true, 但是如果是空字符串、空列表也返回true 例子 输出结果 例子2 输出结果 any() 把序列中每一个元素做布尔运算,如果有一个为true就返回true, 但是有两
