1.数据结构
input_dict = {
'A': {
'B': {
'C': {},
'D': {}
},
'E': {
'F': {}
}
},
'G': {
'H': {},
'I': {}
}
}
2. Python 代码
def convert_dict_to_numbers(input_dict, current_key="", level=1):
result = {}
for key, value in input_dict.items():
new_key = f"{level}" if current_key == "" else f"{current_key}.{level}"
result[new_key] = key
if isinstance(value, dict):
result.update(convert_dict_to_numbers(value, new_key, 1))
level += 1
return result
3. 输出结果
result = convert_dict_to_numbers(input_dict)
print(result)
{'1': 'A',
'1.1': 'B', '1.1.1': 'C', '1.1.2': 'D', '1.2': 'E', '1.2.1': 'F', '2': 'G', '2.1': 'H', '2.2': 'I'
}
