在Python中,矩阵遍历有多种方法,以下是几种常见的方法:
- 使用嵌套循环遍历:
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] for i in range(len(matrix)): for j in range(len(matrix[i])): print(matrix[i][j])
- 使用列表推导式遍历:
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] elements = [element for row in matrix for element in row] print(elements)
- 使用NumPy库遍历:
import numpy as np matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] np_matrix = np.array(matrix) for row in np_matrix: for element in row: print(element)
- 使用NumPy库的flat属性遍历:
import numpy as np matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] np_matrix = np.array(matrix) for element in np_matrix.flat: print(element)
这些方法可以根据具体需求选择适合的方式遍历矩阵。
