Python：操纵列表

问题

我必须从一个文本文件到一个列表，对角线，从上到下。它应该适用于

letters.txt

的任何维度。该文件如下所示：

文本文件：letters.txt（虽然这很难，但我从我原来的帖子中删除了“Y”和“Z”

列表应如下所示：

topButtom_List = ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

bLeftToURight = ['A', 'GB', 'MHC', 'SNID', 'TOJE', 'UPKF', 'VQL', 'WR', 'X']

# top to buttom
topButtom_List = [] #should be ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

openFile = open("letters.txt")
for i in openFile:
    i = i.replace(" ","")
length = len(i)
openFile.close()

openFile = open("letters.txt")   
counter = 0   
for eachIterration in range(length):
    for line in openFile:
        line = line.replace(" ","")
        # counter should be added by 1 each time inner loop itterates x4, and outter loop x1.
        topButtom_List.append(line[counter]) 
    counter = counter + 1
openFile.close()

从上到下的当前代码：

topButtom_List = ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

bLeftToURight = ['A', 'GB', 'MHC', 'SNID', 'TOJE', 'UPKF', 'VQL', 'WR', 'X']

# top to buttom
topButtom_List = [] #should be ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

openFile = open("letters.txt")
for i in openFile:
    i = i.replace(" ","")
length = len(i)
openFile.close()

openFile = open("letters.txt")   
counter = 0   
for eachIterration in range(length):
    for line in openFile:
        line = line.replace(" ","")
        # counter should be added by 1 each time inner loop itterates x4, and outter loop x1.
        topButtom_List.append(line[counter]) 
    counter = counter + 1
openFile.close()

我试图用上面的代码做什么：

topButtom_List = ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

bLeftToURight = ['A', 'GB', 'MHC', 'SNID', 'TOJE', 'UPKF', 'VQL', 'WR', 'X']

# top to buttom
topButtom_List = [] #should be ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

openFile = open("letters.txt")
for i in openFile:
    i = i.replace(" ","")
length = len(i)
openFile.close()

openFile = open("letters.txt")   
counter = 0   
for eachIterration in range(length):
    for line in openFile:
        line = line.replace(" ","")
        # counter should be added by 1 each time inner loop itterates x4, and outter loop x1.
        topButtom_List.append(line[counter]) 
    counter = counter + 1
openFile.close()

我试图从文本文件中获取从顶部到按钮的字符，并将其放入名为

topButtom_list

的列表中。我使用计数器定义索引，对于外部循环所做的每一次迭代，索引将被添加1。依我看，外部循环将启动，内部循环将在

topButtom_List

在第一次迭代时，外循环将再次迭代并向计数器添加1。

BHNTZ

将在第二次迭代时添加，依此类推，外循环将再次迭代并向计数器添加1

从文本文件：letters.txt 我想填充

topButtom\u列表

我得到的输出：

topButtom_List = ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

bLeftToURight = ['A', 'GB', 'MHC', 'SNID', 'TOJE', 'UPKF', 'VQL', 'WR', 'X']

# top to buttom
topButtom_List = [] #should be ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

openFile = open("letters.txt")
for i in openFile:
    i = i.replace(" ","")
length = len(i)
openFile.close()

openFile = open("letters.txt")   
counter = 0   
for eachIterration in range(length):
    for line in openFile:
        line = line.replace(" ","")
        # counter should be added by 1 each time inner loop itterates x4, and outter loop x1.
        topButtom_List.append(line[counter]) 
    counter = counter + 1
openFile.close()

预期输出：

topButtom_List = ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

bLeftToURight = ['A', 'GB', 'MHC', 'SNID', 'TOJE', 'UPKF', 'VQL', 'WR', 'X']

# top to buttom
topButtom_List = [] #should be ['AGMS', 'BHNT', 'CIOU', 'DJPV', 'EKQW', 'FLRX']

openFile = open("letters.txt")
for i in openFile:
    i = i.replace(" ","")
length = len(i)
openFile.close()

openFile = open("letters.txt")   
counter = 0   
for eachIterration in range(length):
    for line in openFile:
        line = line.replace(" ","")
        # counter should be added by 1 each time inner loop itterates x4, and outter loop x1.
        topButtom_List.append(line[counter]) 
    counter = counter + 1
openFile.close()

有趣的问题！试着自己解决它，用你所缺少的东西发布你的尝试来完成它，我们很乐意帮助：）添加代码。我不知道我该怎么问，我的帖子总是投反对票。我修正了投票，但是仅仅发布你的代码对我们没有帮助。你还需要解释什么不适用于它，并给出输入和输出的示例…纠正了一些变量你只是问如何做向上/向下或向左/向右谢谢！那很有用！有没有办法做到不间断？嗨，我的代码有问题，如果我在你的代码中的字段变量上使用不同维度的文本，它只会得到其中的一部分，其他的只会在列表上打印一个空格。
