Append integer to beginning of list in Python

To append an integer to the beginning of a list in Python, you can use the insert() method. Here's an example:

my_list = [1, 2, 3]
my_list.insert(0, 4)
print(my_list) # Output: [4, 1, 2, 3]

In the example above, the insert() method is used to insert the integer 4 at the index 0 of the list my_list. This effectively adds the integer to the beginning of the list. The first argument to the insert() method is the index where the element should be inserted, and the second argument is the element itself.
