下面是一个简单的 Python 细胞计数器程序:
```python
import queue
def read_cell_picture(file_path):
with open(file_path, 'r') as f:
lines = f.readlines()
m, n = map(int, lines[0].strip().split())
matrix = [[int(x) for x in line.strip()] for line in lines[1:]]
return matrix, m, n
def explore_pixel(matrix, m, n, i, j):
q = queue.Queue()
q.put((i, j))
while not q.empty():
x, y = q.get()
if matrix[x][y] < 0:
continue
matrix[x][y] = 0 - matrix[x][y]
if x > 0 and matrix[x-1][y] > 0:
q.put((x-1, y))
if x < m-1 and matrix[x+1][y] > 0:
q.put((x+1, y))
if y > 0 and matrix[x][y-1] > 0:
q.put((x, y-1))
if y < n-1 and matrix[x][y+1] > 0:
q.put((x, y+1))
def count_cells(file_path):
matrix, m, n = read_cell_picture(file_path)
count = 0
for i in range(m):
for j in range(n):
if matrix[i][j] > 0:
count += 1
explore_pixel(matrix, m, n, i, j)
return count
if __name__ == '__main__':
file_path = 'cellpicture.txt'
count = count_cells(file_path)
print('Found {} cells.'.format(count))
```
这个程序与之前的 C++ 版本类似,也使用了 BFS 算法来遍历图像中的每个像素点。不同之处在于,Python 中使用了 `queue` 模块来实现队列,而且在读取文件时也使用了 Python 的文件读取方式。
