copy( ) FUNCTION

The copy( ) Function is used to make a copy of the Dictionary.

Example :

x = {
    5 : "Is a Number", 
    "John": "Is a Name", 
    "Python": "Is a Language"
}
y = x.copy()
print("The Copied Dictionary is ",y)

Output :

The Copied Dictionary is {5: 'Is a Number', 'John': 'Is a Name', 'Python': 'Is a Language'}

Similarly, in the above code we have created a 'Dictionary' and initialised to the variable 'x'.

x = {
    5 : "Is a Number", 
    "John": "Is a Name", 
    "Python": "Is a Language"
}

Then we have used the 'copy( )' method that Dictionary 'x' invokes and creates a new Dictionary that would be the exact copy of 'x'.

Then assign it to 'y'.

y = x.copy( )

And if we see the below output,

The Copied Dictionary is {5: 'Is a Number', 'John': 'Is a Name', 'Python': 'Is a Language'}

The new variable 'y' is an exact copy of 'x'.

Note : Do not use the '=' operator to copy a Dictionary to the other(i.e. If there are two Dictionaries 'x' and 'y'. Do not use y = x). Because in that case any changes made to the Dictionary 'x' will be reflected in the copied Dictionary 'y'.
