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

问题描述

我正在尝试创建一个简单的首字母缩略词定义 GUI。我大部分时间都拥有它。我的目标是实现两种不同类型的输出。如果用户输入 A，我希望它输出所有以 A 开头的首字母缩略词，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略词，而不仅仅是 ACL 首字母缩略词。我怀疑错误或非错误可能来自 .join

解决方法

就我而言，您在 loop_over_input 中以错误的方式检查它，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 - startswith() 开头。它解决了错误输出的问题。

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

当用户写入 .upper() 时，我也会使用 AWS 来获取 aws。

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，所以我在

中使用 "\n" 而不是 ","

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

编辑：

我会使用 regex 来使用更复杂的搜索，即。 I$ 获取以 I 结尾的字符串。

最终我会使用 fnmatch 来搜索星号 - '*I' 或 'A*S'

---

带有 regex 的代码

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,re.I):  # check in any place of string
            master_list.append(f'{key} - {value}')

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

所有以 S 结尾的键
