From Python...
s = "hello, %s. Where is %s?" % ("John","Mary")
How do you do that in Ruby?

Almost the same way:
irb(main):003:0> "hello, %s. Where is %s?" % ["John","Mary"]
=> "hello, John. Where is Mary?"

In Ruby, do the square brackets mean a tuple? I thought square brackets are lists...

Ruby doesn't have tuples (at least not forged into the language). Yeah, it's an array ("list" in Python should really be called arrays...).

The easiest way is string interpolation. You can inject little pieces of Ruby code directly into your strings.
name1 = "John"
name2 = "Mary"
"hello, #{name1}. Where is #{name2}?"
You can also do format strings in Ruby.
"hello, %s. Where is %s?" % ["John", "Mary"]
Remember to use square brackets there. Ruby doesn't have tuples, just arrays, and those use square brackets.

The first one won't work, the #{} looks for a variable, so in this case it'd be printing the John variable, not the string "John".The second one looks correct.
