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)

Another way to make a copy is to use the built-in method dict().

Example

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

thisdict = {

  "brand": "Ford",

  "model": "Mustang",

  "year": 1964

}

mydict = dict(thisdict)

print(mydict)
