Python - Copy Dictionaries
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 function
dict()
.
Example
Make a copy of a dictionary with the dict()
function:
thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
mydict
= dict(thisdict)
print(mydict)
