在实际编程中,我们可以通过transpose()方法来处理嵌套列表。首先,我们需要创建一个嵌套列表,然后调用transpose()方法对其进行转置。下面是一个简单的示例: matrix = [[1, 2], [3, 4], [5, 6]] transposed_matrix = matrix.transpose() print(transposed_matrix) 运行上述代码,我们可以得到与之前相同的结果: [...
In the above example, thetranspose()function returns a new array with the axes switched. In the case of the 2D array like our list, the rows and columns have been swapped. You will notice that all three examples return the same results, but in slightly different structures. Therefore, sele...
