How do I concatenate two lists in Python?
You can concatenate two lists in Python by using the +
operator or the extend()
method.
Here is an example using the +
operator:
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list3 = list1 + list2
print(list3) # Output: [1, 2, 3, 4, 5, 6]
Here is an example using the extend()
method:
list1 = [1, 2, 3]
list2 = [4, 5, 6]
list1.extend(list2)
print(list1) # Output: [1, 2, 3, 4, 5, 6]
Note that the extend()
method modifies the list in place, whereas the +
operator creates a new list.
