2 >>> a_dict
3 {‘sky‘: ‘asdf‘, ‘liao‘: ‘asdf‘}
4 >>> b_dict = {‘xiong‘: ‘asdf‘, ‘asky‘: ‘asdf‘}
5 >>> b_dict
6 {‘xiong‘: ‘asdf‘, ‘asky‘: ‘asdf‘}
7 >>> c_dict = dict(a_dict, **b_dict)
8 >>> c_dict
9 {‘sky‘: ‘asdf‘, ‘liao‘: ‘asdf‘, ‘xiong‘: ‘asdf‘, ‘asky‘: ‘asdf‘}

 5 >>> b_dict
 6 {‘xiong‘: ‘asdf‘, ‘asky‘: ‘asdf‘}
 7 >>> c_dict = a_dict.copy()
 8 >>> c_dict.update(b_dict)
 9 >>> c_dict
10 {‘sky‘: ‘asdf‘, ‘liao‘: ‘asdf‘, ‘xiong‘: ‘asdf‘, ‘asky‘: ‘asdf‘}
