What does “$” symbol mean in Lua?

Question

I wonder how the dollar symbol $ is used in Lua.

Is it reserved for anything?

If so, I would appreciate an example of it.

Answer 1

its is not a part of the language It is used to show the parts that are usually executed in any language (ie what is usually written at execution on the compiler)

in python you first open up cmd then type

$ python  
$ from pywinauto.application import Application

but u dont actually type the $ when u are actually typing in command prompt

you just type

from pywinauto.application import Application

the $ is used to show that it what is and executed step when in the documentation phase.
