Dictionary in Python

[snippsat]

I still have n't the answer for my original question. Can someone help answer it?

@DeaD_EyE has aswers it,maybe you did not understand his explanation.
Both point to same object in memory,so all changes will affect both.

>>> current = {}
>>> new_dict = current
>>> id(current)
201281040
>>> id(new_dict)
201281040

To copy the mutable types like dictionaries,use copy/deepcopy.

>>> from copy import deepcopy
>>> 
>>> current = {}
>>> new_dict = deepcopy(current)
>>> id(current)
203313200
>>> id(new_dict)
127766128

from copy import deepcopy

current = {}
new_dict = deepcopy(current)
print("Current Dict:",current)
print("New Dict:",new_dict)
current[1]={}
print("Current Dict:",current)
print("New Dict:",new_dict)

Output:
Current Dict: {}
New Dict: {}
Current Dict: {1: {}}
New Dict: {}
