python - 如何创建自定义字典输出。当前拿起第一个字母并给出输出

Question

我正在尝试创建一个简单的首字母缩写词定义 GUI。我大部分都拥有它。我的目标是实现两种不同类型的输出。如果用户输入 AI 希望它输出所有以 A 开头的首字母缩写词，就会发生这种情况。例如，当我键入 ACL 时，它会再次带回所有首字母缩写词，而不仅仅是 ACL 首字母缩写词。我怀疑错误或非错误可能来自 .join

至于我，您以错误的方式检查它，loop_over_input这会导致显示正确输出的问题。

您应该从字典中获取键并检查每个键是否以用户文本开头 - startswith()。它解决了错误输出的问题。

然后你就不需要"A": "..."了，因为它会找到所有以 . 开头的项目"A"。

当用户写入时，我也会使用.upper()get 。AWSaws

def loop_over_input(the_str=''):
    master_list = []
    
    for key, value in passwordConversion.items():
        if key.upper().startswith(the_str.upper()):
            master_list.append(f'{key} - {value}')

    print("Master Pass List: ", master_list)
    return master_list

因为master_list有列表所以我使用"\n"而不是", "in

textin = "\n".join(loop_over_input(entered))

编辑：

我会使用regex更复杂的搜索，即。I$最后得到字符串I。

最终我会使用fnmatch来搜索 star -'*I'或'A*S'

---

代码与regex

import re

def loop_over_input(the_str=''):
    master_list = []
    
    for key, value in passwordConversion.items():
        #if re.match(the_str, key, re.I):  # check at the beginning of string
        if re.search(the_str, key, re.I):  # check in any place of string
            master_list.append(f'{key} - {value}')

    print("Master Pass List: ", master_list)
    return master_list

以结尾的所有键S
