list1 = [1, 2, 3]
list2 = [4, 5, 6]
combined_list = list1 + list2  # Combine lists correctly
print("combined_list:", combined_list)

dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}
combined_dict = {**dict1, **dict2}  # Combine dictionaries using unpacking

# Expanding Sequence Elements with the Spread Operator

The `Spread Operator` is commonly used to unpack or expand elements of data structures like lists, tuples, and dictionaries into other data structures.

The spread operator can be utilized in various situations such as passing **arguments to functions**, **merging lists**, or **assigning values to variables**.

You can unpack elements of a list or dictionary using the `*` spread operator as shown below.

```python title="Using Spread Operator with Lists"
numbers = [1, 2, 3]

print("numbers:", *numbers)
# Output: 1 2 3
```

The unpacked elements are printed with a space between each element.

## Using the Spread Operator with Lists

You can also use the spread operator to merge two lists as shown below.

```python title="List Merging Example"
a = [1, 2, 3]
b = [4, 5, 6]

combined = [*a, *b]
print("combined:", combined)
# Output: [1, 2, 3, 4, 5, 6]
```

<br />

## Using the Spread Operator with Dictionaries

When using the `*` spread operator with dictionaries, only the `keys` are unpacked.

```python title="Using Spread Operator with Dictionaries"
dict1 = {'a': 1, 'b': 2}

print("dict1:", *dict1)
# Output: a b
```

<br />

If you want to unpack both key-value pairs, you need to use `**` to expand the dictionary.

```python title="Unpacking Key-Value Pairs with Spread Operator"
dict1 = {'a': 1, 'b': 2}
dict2 = {'c': 3, 'd': 4}

combined = {**dict1, **dict2}
print("combined:", combined)
# Output: {'a': 1, 'b': 2, 'c': 3, 'd': 4}
```

<br />

As demonstrated, the spread operator is primarily used for expanding or merging data types such as lists, tuples, and dictionaries.

To unpack both key-value pairs in a dictionary, you need to use the `**` operator.

### Using the `*` operator in a dictionary can unpack key-value pairs.
