如何将字符串列表转换为只有未知索引处的特定类型才能成为键的dict？

def convert_list_to_dict(lst, key_type):
    result_dict = {}
    for index, value in enumerate(lst):
        key = key_type(index)
        result_dict[key] = value
    return result_dict

# 示例用法
string_list = ['apple', 'banana', 'orange']
key_type = int  # 将索引转换为整数类型作为键
result = convert_list_to_dict(string_list, key_type)
print(result)

{0: 'apple', 1: 'banana', 2: 'orange'}
