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...
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.(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], ...

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],[2,5,8],[3,6,9]] Example 2: Input:[[1,2,3],[4,5,6]] Output:[[1,4],[...
python知识讲解English 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 ...
matrix = [ [1,2,3,4], [5,6,7,8], [9,10,11,12] ] print(transpose1(matrix)) print(transpose2(matrix)) print(transpose3(matrix)) 1. 2. 3. 4. 5. 6. 7. 8. output: [Running] python -u "j:\python\matrix.py" [[1, 5, 9], [2, 6, 10], [3, 7, 11], [4, 8...
for j in range(row): temp.append(matrix[j][i]) transposed.append(temp) return transposed transposed = transpose(matrix) print(transposed) 运行上述代码,我们可以得到相同的结果: [ [ 1, 3, 5 ], [ 2, 4, 6 ] ] 总的来说,transpose()方法是一种简洁、高效处理嵌套列表的方法,可以避免繁琐的手...

The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix. 求矩阵的转置 踩了一个python的坑 x = [[0] * n] * m 内层的字数组是同一个,改变[0][1]的同时[1][1] [2][1] ...[m][1]都被改了。因此不能这么初始化...
