Understanding a new programming language takes time. With Python, we can find many ways to make the task of understanding a new language easier. Here are some tips on appending to the front of a list in python that you can use to make the process easier.
How Can You Append To The Front Of A List In Python
Option 1: Utilizing insert()
The insert() function in Python can be used to add items to the front of a list. It will place the object at the beginning of the list. So, let’s take a look at an instance of this:
mylist = [38,45,21,85,35,7] mylist.insert(0, 19) print(mylist)
[19, 38, 45, 21, 85, 35, 7]
Option 2: Utilizing *
You can also include elements to the front of the list utilizing this method. Let’s take a look at this.
mylist = [45,68,51,21,32] insert = 19 newlist = [insert, *mylist] print(newlist)
[19, 45, 68, 51, 21, 32]
Option 3: Utilizing + character
You can also include an element to the front position by utilizing the
+ character. The following example will help you understand this:
num = 19 mylist = [15, 22, 63] print([num] + mylist)
[19, 15, 22, 63]
Option 4: Utilizing unpacking
Excepting the options mentioned above, there is another way for you to append to the front of a list in Python. It is utilizing unpacking.
In Python, a procedure called unpacking makes certain iterable manipulations possible. Iterable assignment is more adaptable and effective for developers because to unpacking. In this example, the operation that will be utilized to insert at the start of the list using unpacking will be combining already-existing iterables. The unpacking
operator * can be used to combine a single integer with an existing list, inserting the result at the start of the new list, and append one element to the beginning of a list. Look at the following example to understand about this method:
to_insert = 7 int_list = [19, 22, 40, 1, 78] int_list = [to_insert, *int_list] print(int_list)
[7, 19, 22, 40, 1, 78]
