how to pick all numbers in the range from x to y?
this is probably a stupid question, but i got random number and now i need to get all numbers in the range from 1 to 3 and 4 to 7. how do i do this? example:
local numb = math.random(1,7)
if numb == 1,3 then --incorrect line
print("1")
elseif numb = 4,7 then --incorrect line
print("2")
etc.

You could use the or operator like so:
local numb = math.random(1,7)
if numb == 1 or numb == 2 or numb == 3 then -- if it is 1,2 or 3
print("it is a number between 1 and 3 - "..numb)
elseif numb == 4 or numb == 5 or numb == 6 or numb == 7 then -- if it is 4,5,6 or 7
print("it is a number between 4 and 7 - "..numb)
end
Or you could use a table, and the table.find function (recommended):
local numbTable = {
oneToThree = {1,2,3},
fourToSeven = {4,5,6,7}
}
local numb = math.random(1,7)
if table.find(numbTable["oneToThree"],numb) then
print("it is is a number between 1 and 3 - "..numb)
elseif table.find(numbTable["fourToSeven"],numb) then
print("it is is a number between 4 and 7 - "..numb)
end
Hope this helped!

Simple! Use inequalities! (i.e. less than, greater than, less or equal to, etc.)
Heres an example of your code using this!
local numb = math.random(1,7)
if numb >= 1 and numb <= 3 then
print("1")
elseif numb >= 4 and numb <= 7 then
print("2")
end
