如何查看网格和单元格中的内容 Python

Question

我知道这有点远，因为它已经一天了，但是用户输入一组坐标来“放置线”在他们选择的任何单元格中，“*”将放置在网格中。

我的两个主要问题是让网格在 CarpetSea __str__ 方法中显示以及将线也放置在网格中。

这是我当前的代码

Answer 1

要显示网格，您可以在 main() 中进行操作

for y in range(2): 
    for x in range(2): 
       print( info.grid[y][x].fish )
       print( info.grid[y][x].contains_line )

或者如果您在单元格中创建正确的__str__

for y in range(2): 
    for x in range(2): 
       print( info.grid[y][x] )

或保护程序 - 没有range()

for row in info.grid: 
    for cell in row: 
       print( cell )

您也可以在 CarpetSea 中创建函数 - 然后使用 self 而不是 info

def display(self):

    for row in self.grid: 
        for cell in row: 
           print( cell )

---

Cell 中的__str__ 需要if/elif/else 才能正确显示值

def __str__(self):
    '''
    '''

    if self.fish: # the same as: if self.fish == ''
        if self.contains_line: # the same as: if self.contains_line == True"
            result = 'F*'
        else:
            result = 'F'
    else:
        if self.contains_line:
            result = '*'
        else:
            result = ' '

    return result
