When working with lists in Python, the append()<\/b> method is frequently used to add elements to a list. However, it is essential to understand whether the append()<\/b> method modifies the reference or the value of a list. Let’s delve into this question to gain a clear understanding.<\/p>\n
The answer to the question “Does append change the reference or the value in Python?” is: append() modifies the value of the list, not the reference.<\/b> This means that the reference to the list remains the same, but the list itself is altered by adding the new element.<\/p>\n
To demonstrate this, let’s consider the following example:<\/p>\n
“`python
\nmy_list = [1, 2, 3]
\nprint(“Original List:”, my_list)
\nmy_list.append(4)
\nprint(“Modified List:”, my_list)
\n“`<\/p>\n
Output:<\/p>\n
“`
\nOriginal List: [1, 2, 3]
\nModified List: [1, 2, 3, 4]
\n“`<\/p>\n
As you can see, the output showcases that the original list was modified by appending the element ‘4’ to it.<\/p>\n
