赋值添加新键/值
用 .update() 从另一个字典、元组或关键字更新

print(galleries_10007)

{'Nyabinghi Africian Gift Shop': '(212) 566-3336'}

art_galleries['10007'] = galleries_10007

更新字典

galleries_11234 = [
  ('A J ARTS LTD', '(718) 763-5473'),
  ('Doug Meyer Fine Art', '(718) 375-8006'),
  ('Portrait Gallery', '(718) 377-8762')]

art_galleries['11234'].update(galleries_11234)

print(art_galleries['11234'])

{'Portrait Gallery': '(718) 377-8762', 
'A J ARTS LTD': '(718) 763-5473', 
'Doug Meyer Fine Art': '(718) 375-8006'}

del 指令删除键/值
.pop() 安全移除键/值

galleries_10310 = art_galleries.pop('10310')

print(galleries_10310)

{'New Dorp Village Antiques Ltd': '(718) 815-2526'}
