# Python set add method

 

The `add` method in Python is used to add an element to a set. A set is a collection of unique elements in Python. The `add` method adds the specified element to the set if it is not already present.

 

Syntax: `set.add(element)`

 

Parameters:

 

- `element`: The element that you want to add to the set.

 

Return Value:

 

The `add` method does not return any value. It only modifies the set by adding the specified element.

 

Example:

 

Let's consider a simple example to illustrate the usage of the `add` method:

 

```python

# Create a set

my_set = {1

2

3}

 

# Add an element to the set

my_set.add(4)

 

# Print the updated set

print(my_set)

```

 

Output:

```

{1

2

3

4}

```

 

In the above example

we first create a set `my_set` with elements 1

2

and 3. Then

we use the `add` method to add the element 4 to the set. Finally

we print the updated set which now includes the element 4.

 

Now

let's write a program using the `add` method to add 1000 random integers to a set and then print the set:

 

```python

import random

 

# Create an empty set

my_set = set()

 

# Add 1000 random integers to the set

for i in range(1000):

my_set.add(random.randint(1

1000))

 

# Print the set

print(my_set)

```

 

In the above program

we first import the `random` module to generate random integers. Then

we create an empty set `my_set`. We use a loop to add 1000 random integers (between 1 and 1000) to the set using the `add` method. Finally

we print the set which now contains 1000 unique random integers.

 

In conclusion

the `add` method in Python is a convenient way to add elements to a set. It ensures that only unique elements are present in the set

making it useful for various applications where uniqueness is a requirement.
