Python Set copy()

copy() Syntax

The syntax of copy() method is:

set.copy()

Here, the items of the set are copied.

copy() Parameters

The copy() method doesn't take any parameters.

copy() Return Value

The copy() method returns

• the copy of the set

Example 1: Python Set copy()

Output

Original Names:  {'Marie', 'John', 'Charlie'}
Copied Names:  {'Marie', 'John', 'Charlie'}

In the above example, we have used the copy() method to copy the set names. The items of names are copied to new_names.

Here, new_names is the exact copy of names.

Example 2: Copy Set using = operator

We can also copy the set by simply using the = operator.

Output

Original Names:  {'John', 'Marie', 'Charlie'}
Copied Names:  {'John', 'Marie', 'Charlie'}

In the above example, we have used = operator to copy the set names. The items of names are copied to new_names. Here, the = operator works exactly like the copy() method.

Example 3: Add items to the set after copy()

We can also modify the copied set using different methods.

Output

numbers:  {1, 2, 3, 4}
new_numbers:  {1, 2, 3, 4, 5}

In the above example, we have modified the copied set new_numbers using add() method. Here, the copied set is different from the original set because we have added new item 5 to it.
