So having separate arrays like this is not a good design and not flexible. So I would not recommend it. But to answer your question, you can do it like this (but please don't do this):
var wave_array = get("Wave" + str(1))
A better way is to store the whole thing in a Dictionary. Dictionaries can store Arrays as well as other Dictionaries. So you can put everything in one structure.
var Waves = {1 : ["MapName",
"delay", 1000,
1, 3,
"delay", 4000,
1, 2,
"end", 0],
2 : ["MapName",
"delay", 1000,
1, 3,
"delay", 4000,
1, 2,
"end", 0]}
Then you can access it like this:
var wave_1_array = Waves[1]
However, that is still a bad design, and I'm not sure why you are storing the values as loose values in an array. This is very rigid, and if you decided to change anything, or need another value in the middle, you will have to rewrite all your code. It's not very flexible. You want to use a Dictionary (similar to JSON in Javascript) to store your values.
var Wave1 = {
"name" : "level_1"
"delay" : 1000,
"end": 0
}
That way every value has a name. Then access it like this:
var wave_1_delay = Wave1.delay
That said, the best way would be to define your own custom structure (class) to store the wave data. That way you don't have 25 arrays at the top of your script. You can also store the data in text files, like .csv files, which are loaded into the class instances. But this is rather advanced, and I won't explain it cause it would be pretty long, but that would be the correct way to do it.
