掃描和更換嵌套字典

Question

中值如何比較，並根據哪些用戶輸入

Answer 1

dic = {'Sally':['1346','A','April', {'1346': ('week', 6)}], 
     'Annie': ['1347', 'A', 'April', {'1346': ('week', 5)}], 
     'Marie': ['0', 'Absent', 'Fall', {}]} 

for value in dic.values(): 
    for element in value: 
     if isinstance(element, dict) and '1346' in element: 
      element['1346'] = ('month',6) 

，如果這是Python 2中，我會用dic.itervalues()代替dic.values()代替嵌套的字典裏鍵。

而這裏的結果：

>>> import pprint 
>>> pprint.pprint(dic) 
{'Annie': ['1347', 'A', 'April', {'1346': ('month', 6)}], 
'Marie': ['0', 'Absent', 'Fall', {}], 
'Sally': ['1346', 'A', 'April', {'1346': ('month', 6)}]}
