Question

for problem set 3, how do refresh the tuple inside the function if you use the function more than once?

Answer 1

Not sure what you mean by your question. A tuple doesn't get refreshed. Do you want to start the tuple from scratch again and rerun the function? You can just redeclare the tuple as an empty tuple before you run the function on it again.

Answer 2

if you are passing a tuple to a function - pass an empty tuple
if the tuple is created 'inside' the function it shouldn't need to be refreshed

Answer 3

thx guys, I guess my question wasn't really clear. what i meant was, my function subStringMatchExact returns a tuple z(), in which I add the starting points of "key" in "target". However, if i use the function more than once, the values returned from the different uses gets stacked together. so i was wondering how would I solve this problem. thx a lot

Answer 4

hmm, it might be easier if you posted your code - using dpaste.com or codepad.com or pastebin.com .......

if you have a variable that points to a tuple and at some point you want the variable to point to an empty tuple then just reassign the variable to an empty tuple: http://pastebin.com/5KCwKqhd
