1. The problem statement, all variables and given/known data My professor wants us to program on Python, where we have a certain sequence, for example: sequence = ("one", "two", "three", "four") I need to replace one of the sequence elements (example: "one") with another element (example: instead of the word "one", I need to put "zero"). 2. The attempt at a solution I really have no idea how to do it, but I guess I have to start with. sequence = ("one", "two", "three", "four") Do I need to use something like: sequence [1 : : 2] or something else? Would really appreciate if you guys would help. I would appreciate even a hint or advice on which path to take to be able to write this.
