Ruby is a general-purpose programming language and it's syntax is close to Python's own.
When I started learning Ruby, I was marveled at it's simplicity.
Since I was coming from a Python background. I found it very easy to learn. Because of it's similarity in syntax, I wanted some of Python's function in Ruby.
One of the functions I wanted to implement was the input() function. The reason was that, Ruby unlike Python, you will need to use both puts and gets if you want to get a user's input whiles displaying text in Ruby.
Creating our function
Well, to create this function in Ruby is very simple. Just open your Ruby file and type the following code inside
def input(prompt ='')
puts prompt
return gets
end
Explaining the function
Well, so as we can see, the function is just four lines of code. Pretty simple huh!
The function was made to just replicate Python's own so they work in the same way.
The input function takes an optional parameter called prompt. On the next line, the puts method displays the prompt to stdout and then the gets method retrieves any user input and returns it.
Trying out the function
In order to use the method we just created, make sure the code is in the same file as the one you are working with.
name = input("What is your name?")
print "Hello " + name
In our example, we called our function with the string "What is your name?" and the value was stored in the variable name. On the next line, we printed 'Hello' + name.
See, that wasn't hard! 😄

Currently learning a bit of ruby through CodeAcademy, and this makes me so happy! I'm a total beginner, but same as you, my self taught 'background' (albeit thin) is python.
