演算子 `+` を使えば、次のように2つのリストを連結することができる：
```py
list1 = [1, 2, 3]
list2 = [4, 5, 6]
concatenated = list1 + list2

print(concatenated)
# [1, 2, 3, 4, 5, 6]
```
You can concatenate two lists using the `+` operator, like so:
```py
list1 = [1, 2, 3]
list2 = [4, 5, 6]
concatenated = list1 + list2

print(concatenated)
# [1, 2, 3, 4, 5, 6]
```
