    Strings are immutable so you can't insert characters into an existing string. You have to create a new string. You can use string concatenation to do what you want:

    yourstring = "L" + yourstring + "LL"
    

    Note that you can also create a string with n Ls by using multiplication:

    m = 1
    n = 2
    yourstring = ("L" * m) + yourstring + ("L" * n)
