Is there anything similar to zip() from python in lua?
something like this:
1 | local peoples = { 'joe', 'jogn', 'gfajkg' } |
2 | local secrets = { 'agag', 'gafggf', 'gagfdg' } |
3 | local reasons = { 'sometyhing', 'another thing', 'ffszdgsg' } |
4 |
5 | for index, name in next, peoples do |
6 | local secret = secrets[index] |
7 | local reason = reasons[index] |
8 | print (name, 'is hiding', secret, 'because', reason) |
9 | end |
could be:
1 | local peoples = { 'joe', 'jogn', 'gfajkg' } |
2 | local secrets = { 'agag', 'gafggf', 'gagfdg' } |
3 | local reasons = { 'sometyhing', 'another thing', 'ffszdgsg' } |
4 |
5 | for name, secret, reason in zip(peoples, secrets, reasons) do |
6 | print (name, 'is hiding', secret, 'because', reason) |
7 | end |

Quick question, why are you using different tables and not a dictionary? MineBlox_Artz 65 — 4y

No, but you can write your own
01 | local function zip(First, Second, Third) |
02 | local Index = 0 |
03 |
04 | return function() |
05 | Index += 1 |
06 |
07 | local NextFirst = First[Index] |
08 | local NextSecond = Second[Index] |
09 | local NextThird = Third[Index] |
10 |
11 | if not NextFirst or not NextSecond or not NextFirst then |
12 | return nil |
13 | end |
14 |
15 | return NextFirst, NextSecond, NextThird |

the way this works is that zip returns a function which is being called every iteration, in the function i increment the index by 1 every time to create a loop, then it returns elements from each table with given index, if at least one of the elements is nil it breaks the loop.
I am not a pythoneer so i am not sure if this is how the function is supposed to work but i think it fits your example. You can adjust it how you need, i made it simple so you can understand it.
