Copy Dictionaries

Copying dictionaries shares the same reference pitfalls as lists, solved with copy() and dict(). Learn to duplicate mappings safely.


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

thisdict =	{
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964
}
mydict
= thisdict.copy()
print(mydict)

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

Example

thisdict =	{
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964
}
mydict
= dict(thisdict)
print(mydict)
