I'm trying to transpose a matrix in Python. The function should change the original variable. When I've looked up similar problems, they talk about editing the variable 'in place', but when I tried that I had problems that once an element was changed, it would use the new changed element in later steps, so the result wouldn't be a transpose, and would have some elements missing and some doubled. So I tried making a copy, copying term by term, and then copying back, and it seemed to work, except it only works inside the function. As in, in the code block below, print#1 is correct, but print#2 is not (it's the original matrix). How can I change the original matrix? Thanks for any help Oh also, trying to do this without importing anything (deepcopy, transpose), as I haven't learnt that yet. # Write your solution here def transpose(matrix: list): newmatrix = [] for r in range (len(matrix)): temp = [] for c in range (len(matrix)): temp.append(matrix[c][r]) newmatrix.append(temp) matrix = [] for r in range (len(newmatrix)): temp = [] for c in range (len(newmatrix)): temp.append(newmatrix[r][c]) matrix.append(temp) print(matrix) #1 matrix = [[1,2,3],[4,5,6],[7,8,9]] transpose (matrix) print(matrix) #2 Continue reading...
