How to add a value to the end of a list in Python?

To add a value to the end of a list in Python, the append() method is used.

# Create a list
my_list = [1, 2, 3]

# Add the value 4 to the end of the list
my_list.append(4)

# Print the updated list
print(my_list)

You can also use slices with assignment, but this is less idiomatic for simple appending to the end.

# Create a list
my_list = [1, 2, 3]

# Add the value 4 to the end of the list using a slice
my_list[len(my_list):] = [4]

# Print the updated list
print(my_list)

The append() method is the most common and recommended way, as it is more readable and usually more efficient.
