As shown in the image, I got a warning in PyCharm at the list index positions like [0][1][2].... The program still runs, but I don't understand what this warning means or how to resolve it.

invitation_list = ["Allen", "Lucas", "Peter"]
message = "Pls come to my house for the dinner,"
print(f"{message} {invitation_list[0]}, {invitation_list[1]}, {invitation_list[2]}.")

print(f"But, {invitation_list[0]} can not join the dinner.")

invitation_list[0] = "John"
message_2= "I just found a bigger table."
print(message_2)
