How do i implement a function that takes in 3 parameters' tuple index and a value and change the value at the index to a new val

Answer 1

My version would have been this:

def change_tup(tup, idx, val):
return tup[:idx]+(val,)+tup[idx+1:]

Answer 2

Yeah, when you use just parentheses for a single value, Python will just dissolve them, like in (1+2)*3.
