Python copy List is one of the List methods used to shallow copy a Lists. I mean, copying list into a new list. The syntax of the Python list copy function is
list_name.copy()
Python List copy Function Example
The copy function copies total items in a given list to a new list. The below code copy list a to newList.
a = [10, 20, 30, 40]
print("Original List : ", a)
newList = a.copy()
print("Copied List : ", newList)
Original List : [10, 20, 30, 40]
Copied List : [10, 20, 30, 40]In this Python list copy example, we declared a string list. Next, we used the copy function on it.
strFruits = ['Apple', 'Banana', 'Kiwi', 'Grape']
print("Original List : ", strFruits)
newList = strFruits.copy()
print("Copied List : ", newList)
TIP: Please refer to List and List methods articles in Python.
This List copy method example shallow copies the list items into a completely new list.
# List copy
Fruits = ['Apple', 'Orange', 'Banana', 'Kiwi', 'Grape', 'Blackberry']
numbers = [9, 4, -5, 0, 22, -1, 2, 14]
print("Original List : ", Fruits)
print("Original number List : ", numbers)
#Copying the List
New_Fruits = Fruits.copy()
print("\nNew List : ", New_Fruits)
new_numbers = numbers.copy()
print("New Number List : ", new_numbers)
Original List : ['Apple', 'Orange', 'Banana', 'Kiwi', 'Grape', 'Blackberry']
Original number List : [9, 4, -5, 0, 22, -1, 2, 14]
New List : ['Apple', 'Orange', 'Banana', 'Kiwi', 'Grape', 'Blackberry']
New Number List : [9, 4, -5, 0, 22, -1, 2, 14]copy List Function Example 2
Let me use this list copy function on Mixed List.
MixList = ['apple', 1, 'Banana', 5, 'Kiwi', 'Mango']
print("Original List : ", MixList)
newList = MixList.copy()
print("Copied List : ", newList)
Original List : ['apple', 1, 'Banana', 5, 'Kiwi', 'Mango']
Copied List : ['apple', 1, 'Banana', 5, 'Kiwi', 'Mango']In this program, we used List copy function on the Nested list (list inside a list).
MixList = [[71, 222], [222, 13], [14, 15], [99, 77]]
print("Original List : ", MixList)
newList = MixList.copy()
print("Copied List : ", newList)
Original List : [[71, 222], [222, 13], [14, 15], [99, 77]]
Copied List : [[71, 222], [222, 13], [14, 15], [99, 77]]
