why I always hear strings are immutable
what does the mean of strings are immutable, if i can change the string by adding something else to it if i use it again?
first_name = "omri"
first_name = first_name + "lahav"
i just changed the string so what so immutable here?

This code isn't actually changing the original string. It's building a new string by copying the original one along with the additional characters, and then reassigning the same variable with the new string.
You can demonstrate the immutability of strings by trying to change just one character inside one, for example:
first_name = "omri" print(first_name) # this will show "m" first_name = "x" # but this will fail
