jean paul how to add a value at the first position of a list in python? in python

To add a value at the first position (index 0) of a list in Python, we can use the insert method of a list object. Here is an example code snippet:

main.py
my_list = [2, 3, 4, 5]
my_list.insert(0, 1)
print(my_list)
59 chars
4 lines

Output:

main.py
[1, 2, 3, 4, 5]
16 chars
2 lines

In the above code, we first initialize a list my_list with some values [2, 3, 4, 5]. Then, we call the insert method on this list and pass two arguments: the index where we want to insert the value (in this case, 0 for the first position), and the value we want to insert (in this case, 1). This inserts the value 1 at the beginning of the list. Finally, we print the updated list to the console to verify the changes.
