Lua 用于范围内的变量 [英] Lua For Variable In Range

问题描述

我似乎无法让它发挥作用.我来自 Python，所以我尝试对它使用相同的语法，但不出所料，它不起作用:

I can't seem to get this to work. I come from Python, so I tried using the same syntax for the hell of it, but it unsurprisingly wouldn't work:

var = 4

for var in range(2,20) do
print ("var is in range")
      end

推荐答案

如果你想测试一个值是否在一个范围内，使用

If you want to test whether a value is in a range, use

if var>=2 and var<=20 then
   print ("var is in range")
end

如果你想要一个循环，使用

If you want a loop, use

for var=2,20 do
   print(var)
end
