Copy a Dictionary

You cannot copy a dictionary simply by typing dict2 =

dict1, because: dict2 will only be a

reference to dict1, and changes made in

dict1 will automatically also be made in

dict2.

There are ways to make a copy, one way is to use the built-in Dictionary

method

copy().

Example

Make a copy of a dictionary with the copy() method:



thisdict = {

  "brand": "Ford",

  "model": "Mustang",

  "year": 1964

}mydict

= thisdict.copy()

print(mydict)
