zip(*a) 这个写法使用了两个 Python 的重要特性: zip() 函数:将多个可迭代对象中的元素一一对应地组合起来,创建一个元组的迭代器 * 解包操作符:将列表/元组解包成独立的参数 具体来说: matrix = [ [1, 2, 3], [4, 5, 6] ] # *a 会将 matrix 解包成: # [1, 2, 3], [4, 5, 6] # zi...
The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix.(一矩阵A,返回其转置) 【思路】 直接处理,A[i][j]的值赋值给output[j][i]. 【python代码】 1input = [[1, 2, 3], [4, 5, 6]]2row =len(input)3col =len(...

[LeetCode&Python] Problem 867. Transpose Matrix Given a matrixA, return the transpose ofA. The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix. Example 1: Input:[[1,2,3],[4,5,6],[7,8,9]] Output:[[1,4,7...
In Python, the concept of "transpose" typically refers to swapping the rows and columns of a matrix (or 2D list). If you're encountering an issue where a transpose operation doesn't seem to be working as expected, it could be due to several reasons. Let's explore the basic transpose ...
NumPy Matrix transpose() Python numpy module is mostly used to work with arrays in Python. We can use the transpose() function to get the transpose of an array. import numpy as np arr1 = np.array([[1, 2, 3], [4, 5, 6]]) print(f'Original Array:\n{arr1}') arr1_transpose ...
