【问题描述】：

我必须编写一个程序，它接受三个输入并使用这些输入来确定如何显示由文本文件定义的 ASCII 艺术字字体。我得到的输出几乎是正确的，但是我的程序错误地处理了空格，完全从诸如 HOW DO 之类的东西中省略了它们。这是我的代码：

hi = input('Height: ')
wi = input('Width: ')
tx = input('Text: ')
hi = int(hi)
output = [[] for _ in range(hi)]
with open("font.txt") as fi:
  lines = fi.readlines()

for character in tx:
  offset = int(cd[character])
  start = offset * hi
  end = start + hi 
  letter = lines[start:end] 
  for outputline, letterline in zip(output, letter):
      outputline.append(letterline.rstrip('\n'))
for line in output:
  print(''.join(line))

还有我的输出

Height: 8
Width: 9

注意空格（应该与其他字符大小相同）不显示的方式。

【问题讨论】：

cd 在哪里定义？ [你似乎有一些不必要的初始化程序 - 重复 hi 和不必要的 wi 和 'fi']
这是cd：cd = {'A' : 0, 'B': 1, 'C': 2, 'D': 3, 'E': 4, 'F': 5, 'G': 6, 'H': 7, 'I': 8, 'J': 9, 'K': 10, 'L': 11, 'M': 12, 'N': 13, 'O': 14, 'P': 15, 'Q': 16, 'R': 17, 'S': 18, 'T': 19, 'U': 20, 'V': 21, 'W': 22, 'X': 23, 'Y': 24, 'Z': 25, ' ': 28}
你确定在 font.txt 文件的适当位置有几行空格，print("XXX{}XXX".format(lines[28*hi])) ？ cd 中的 ' ' 索引是 28 而不是 26 的任何原因？

【解决方案1】：

对于那些仍在寻找解决方案的人：

for character in tx:
  offset = int(cd[character])
  start = offset * hi
  end = start + hi
  if character == ' ':
    lines[start:end] = [' ' * int(wi) for _ in range(int(hi))]
  letter = lines[start:end]
