Cloning a List in Python
In this section, we will learn how to copy the elements of one list to another list.
Example 1: Using Slicing
def clone_list(li1):
li_copy = li1[:]
return li_copy
li1 = [4, 8, 2, 10, 15, 18]
li2 = clone_list(li1)
print("Original list:", li1)
print("Copied list:", li2)Output:
Original list: [4, 8, 2, 10, 15, 18] Copied list: [4, 8, 2, 10, 15, 18]
In this example, we use slicing ([:]) to create a shallow copy of the original list.
Example 2: Using extend() Method
def clone_list(li1):
li_copy = []
li_copy.extend(li1)
return li_copy
li1 = [4, 8, 2, 10, 15, 18]
li2 = clone_list(li1)
print("Original list:", li1)
print("Copied list:", li2)Output:
Original list: [4, 8, 2, 10, 15, 18] Copied list: [4, 8, 2, 10, 15, 18]
In this example, we use the extend() method to add elements from the original list to a new list.
Example 3: Using list() Method
def clone_list(li1):
li_copy = list(li1)
return li_copy
li1 = [4, 8, 2, 10, 15, 18]
li2 = clone_list(li1)
print("Original list:", li1)
print("Copied list:", li2)Output:
Original list: [4, 8, 2, 10, 15, 18] Copied list: [4, 8, 2, 10, 15, 18]
In this example, we use the list() constructor to create a copy of the original list.
