PYTHON - COPY FROM SET

How to copy one Set to the other ?

There are two ways by which we can copy one Set to the other.

Using the method 'set( )'

Using the method 'copy( )'

Let us look at the first way using the 'set( )' method.

Example :

x = {"Mohan", "Kriti", "Salim"}
y = set(x)
print("The Copied Set is ",y)

Output :

The Copied Set is {'Mohan', 'Kriti', 'Salim'}

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

x = {"Mohan", "Kriti", "Salim"}

Below is how the values are positioned in the Set ,

Then we have used the 'set( )' method to take the Set 'x' as parameter and create a new Set that would be the exact copy of 'x' .

Then assign it to 'y' .

y = set(x)

And we get the below output ,

The Copied Set is {'Mohan', 'Kriti', 'Salim'}

Now , let us look at the second way of copying a Set using 'copy( )' method.

Example :

x = {"Mohan", "Kriti", "Salim"}
y = x.copy()
print("The Copied Set is ",y)

Output :

The Copied Set is {'Kriti', 'Salim', 'Mohan'}

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

x = {"Mohan", "Kriti", "Salim"}

Below is how the values are positioned in the Set ,

Then we have used the 'copy( )' method that would create an exact copy of 'x' . And assign it to 'y' .

y = x.copy( )

And we get the below output ,

The Copied Set is {'Mohan', 'Kriti', 'Salim'}

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