coding-style - 从复杂的字典中收集特定数据的pythonic方式

Question

我需要根据点符号键名从复杂的字典中收集一些数据

例如

样本数据

data = {
  'name': {'last': 'smith', 'first': 'bob'},
  'address':{'city': 'NY', 'state': 'NY'},
  'contact':{'phone':{'self':'1234', 'home':'222'}},
  'age':38,
  'other':'etc'
}

keys = ['contact.phone.self', 'name.last', 'age']

我的逻辑

result = []
for rev_key in rev_keys:  
  current = data.copy()   
  rev_key = rev_key.split('.')  
  while rev_key:  
    value = rev_key.pop(0)  
    current = current[value]  
  result.append(current)

提前致谢!

[reduce(dict.get, key.split("."), data) for key in keys]
