Converting Python to Ruby - question about main()

Ruby
1

Some Python programs have a couple lines of code like this:

if main == “main”
main()

I think it’s supposed to call the main function if the script is
executed
directly. Is there an equivalent in Ruby? Or is it even necessary in
Ruby?

(I’m new to Ruby, so excuse me if this is a stupid question.)

I’m not entirely sure what that Python code means, but to do
something if the script is executed directly, you can try:

if FILE == $0
(do something)
end

These two snippets of code do the exact same thing: execute code if this
is
the source file being directly executed and not required (ruby) or
imported
(python).

I’m guessing the original poster probably meant this:

if name == ‘main’:
