Python List Add Element to Front

When working with Python lists, you might encounter a situation where you want to add an element to the front of a list. Python provides a few ways to achieve this.

Using the insert Method

One way to add an element to the front of a Python list is to use the insert() method. This method takes two arguments: the index at which to insert the element and the element itself.

my_list = ['apple', 'banana', 'orange']
my_list.insert(0, 'grape')
print(my_list)  # Output: ['grape', 'apple', 'banana', 'orange']

In the example above, we've inserted 'grape' at the beginning of the list by specifying an index of 0.

Using the append and reverse Methods

Another way to add an element to the front of a Python list is to use the append() and reverse() methods. First, append the element to the end of the list and then reverse the list.

my_list = ['apple', 'banana', 'orange']
my_list.append('grape')
my_list.reverse()
print(my_list)  # Output: ['grape', 'orange', 'banana', 'apple']

In the example above, we've appended 'grape' to the end of the list and then reversed the list using the reverse() method.

Using the + Operator

We can also add an element to the front of a Python list by creating a new list with the element we want to add, and then using the + operator to concatenate the two lists.

my_list = ['apple', 'banana', 'orange']
new_list = ['grape']
my_list = new_list + my_list
print(my_list)  # Output: ['grape', 'apple', 'banana', 'orange']

In the example above, we've created a new list with 'grape' and concatenated it with the original list using the + operator.

No matter which method you choose to add an element to the front of a Python list, you now have several options to achieve the desired result.
