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)
Try it Yourself »
"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)
Try it Yourself »
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
mydict = dict(thisdict)
print(mydict)
