arr = ['a', 'b', 'c']
str = arr.each_with_index do |num, i|
  puts "#{i} => #{num}"
end

--output:--
0 => a
1 => b
2 => c
["a", "b", "c"]

You see, each_with_index() is a method call, and it has a return value, 
and the return value is the array you started with.  puts() is also a 
method and it sends text to your screen.  Displaying text on your screen 
does not save the text anywhere.

arr = ['a', 'b', 'c']
result_str = ""

arr.each_with_index do |num, i|
  result_str << "#{i} => #{num}\n"
end

puts result_str  #or add result_str to an email

--output:--
0 => a
1 => b
2 => c

Whoops.  Chopped off a line there:

> p str
