首先需要安装NumPy库,可以使用以下命令进行安装: pipinstallnumpy 1. 然后使用import语句导入NumPy库,并使用argmax()函数获取数组中的最大值下标。 importnumpyasnp# 定义一个数组nums=np.array([10,20,30,40,50])# 获取最大值的索引位置max_index=np.argmax(nums)print("最大值的索引位置:",max_index) 1...

However, what if you want to loop through the cars and find a specific one? And what if you had not 3 cars, but 300? The solution is an array! An array can hold many values under a single name, and you can access the values by referring to an index number. ...
该loop方法创建一个pygame窗口,并在每一帧调用draw方法和loop参数。当我们的仿真需要逐帧更新时,这将变得有用。 AI检测代码解析 import pygame from pygame import gfxdraw import numpy as np class Window: def __init__(self, sim, config={}): # Simulation to draw self.sim = sim # Set default conf...
Loop Over Numpy Array (1d) If we have a one-dimensional Numpy array, looping over it is easy. Consider the following Numpy array: prices = np.array([5,8,12.7,89.6,12.9,5.4]) We can iterate over the elements as follows: 1import numpy as np 2prices = np.array([5,8,12.7,89.6,12...
