删除 .ppm 文件的元组括号

Question

我有这段代码应该反转.ppm 图像的像素。

我能够反转像素，但我一直在删除列表和元组括号列表，以便仅获取整数。

我想要：

 0  0  0  0  0  0    0  0  0   15  0 15
 0  0  0  0 15  7    0  0  0    0  0  0
 0  0  0  0  0  0    0 15  7    0  0  0
15  0 15  0  0  0    0  0  0    0  0  0

我得到了什么：

('15', '0', '15') ('0', '0', '0') ('0', '0', '0') ('0', '0', '0')
('0', '0', '0') ('0', '0', '0') ('0', '15', '7') ('0', '0', '0')
('0', '0', '0') ('0', '15', '7') ('0', '0', '0') ('0', '0', '0')
('0', '0', '0') ('0', '0', '0') ('0', '0', '0') ('15', '0', '15')

代码：

takePPM = input("Enter the pmm file name: ")
try:
    openFile = open(takePPM, "r")
    readFile = openFile.readlines()
except FileNotFoundError:
    print("File not found")
    exit(1)
lists = []
for row in readFile[3:]:
    lists.append(row.split())

#convert each list in lists to lists of 3-tuples
target = []
for list in lists:
    target.append([tuple(list[i:i+3]) for i in range(0,len(list),3)])
revList = []
for i in reversed(target):
    revList.append(i)

#newFile = open("Mirror_" + takePPM, "w")
for row in revList:
    #newFile.write(*row)
    removeList = tuple(row)
    print(*removeList)

注释行是将新的反转像素打印到新文件中，但想先检查一下我得到了正确的格式

Answer 1

您可以将最后一行代码 print(*removeList) 替换为

print(' '.join(''.join(t) for t in removeList))

测试一下：

revList = [[('15', '0', '15'), ('0', '0', '0'), ('0', '0', '0'), ('0', '0', '0')]]
for row in revList:
     #newFile.write(*row)
     removeList = tuple(row)
     print(' '.join(''.join(t) for t in removeList))
