请记住,元组是不可变的数据结构,而列表是可变的,选择使用哪种数据结构取决于您的具体需求。 最后,以类图的形式展示一下元组(Tuple)和列表(List)的关系: converts toTuple-data[]+tuple()+__getitem__()+__len__()List-data[]+list()+append()+remove()+__getitem__()+__len__() 注:尽管在逻辑上...

3. Tuple to Array ConversionWrite a NumPy program to convert a Python tuple to a NumPy array and print the array.Sample Solution:Python Code:import numpy as np # Initialize a Python tuple python_tuple = (1, 2, 3, 4, 5) print("Original Python tuple:",python_tuple) print("Type:",...
my_tuples = [("Name", "John"),("Age", 25),("Occupation", "Analyst")]Now we can convert the created my_tuples to a dictionary, which is a mutable object. Example 1: Transform List of Tuples to Dictionary via dict() FunctionIn this first example, we will use the Python dict()...
使用基于元组的索引和numpy重塑可能是您在这里能达到的最快速度: def vec_to_mat(vec): """Convert an array of shape (N, 6) to (N, 3, 3)""" mat = vec[:, (0, 5, 4, 5, 1, 3, 4, 3, 2)].reshape(-1, 3, 3) return matx = np.array([[1,2,3,4,5,6], [4,6,8,2,...
