Python，从字典中打印单独的索引

Question

下面是我代码的简写版本。基本上，我有一本字典，里面有一个包含我的信的列表。我正在提示用户选择字母，然后用特殊的设计打印出来。第二个用户输入用于决定如何打印字母。'h‘=水平，'v’=垂直。垂直部分工作得很好。水平没有。

def print_banner(input_string, direction):
'''
Function declares a list of ascii characters, and arranges the characters in order to be printed.
'''
ascii_letter = {'a': [" _______ ",
                      "(  ___  )",
                      "| (   ) |",
                      "| (___) |",
                      "|  ___  |",
                      "| (   ) |",
                      "| )   ( |",
                      "|/     \|"]}
    # Branch that encompasses the horizontal banner
if direction == "h":
    # Letters are 8 lines tall
    for i in range(8):
        for letter in range(len(input_string)):
            # Dict[LetterIndex[ListIndex]][Line]
            print(ascii_letter[input_string[letter]][i], end=" ")
            print(" ")

# Branch that encompasses the vertical banner
elif direction == "v":
    for letter in input_string:
        for item in ascii_letter[letter]:
            print(item)


def main():
    user_input = input("Enter a word to convert it to ascii: ").lower()
    user_direction = input("Enter a direction to display: ").lower()
    print_banner(user_input, user_direction)

# This is my desired output if input is aa
_______   _______ 
(  ___  ) (  ___  )
| (   ) | | (   ) |
| (___) | | (___) |
|  ___  | |  ___  |
| (   ) | | (   ) |
| )   ( | | )   ( |
|/     \| |/     \|

#What i get instead is:
 _______ 
 _______ 
(  ___  )
(  ___  )
| (   ) |
| (   ) |
| (___) |
| (___) |
|  ___  |
|  ___  |
| (   ) |
| (   ) |
| )   ( |
| )   ( |
|/     \|
|/     \|

您可以将这些行zip在一起，然后加入它们：

if direction == "h":
    zipped = zip(*(ascii_letter[char] for char in input_string))
    for line in zipped:
        print(' '.join(line))

或者只是索引：

if direction == "h":
    for i in range(8):
        for char in input_string:
            print(ascii_letter[char][i], end=' ')
        print()
