How to convert from Ruby to Python

Before diving into the conversion process, it's crucial to grasp the fundamental differences and similarities between Ruby and Python. Both are high-level, dynamic programming languages, but they have distinct syntaxes and philosophies. Ruby emphasizes the principle of "developer happiness," while Python focuses on readability and simplicity.

Key Differences Between Ruby and Python

  • Syntax: Ruby uses end to mark the end of blocks, whereas Python uses indentation.
  • Variable Declaration: Ruby variables are dynamically typed, while Python also supports dynamic typing but with different conventions.
  • Methods: In Ruby, you call methods using object.method, while Python uses object.method(), with parentheses even for methods without parameters.

Step-by-Step Guide to Converting Ruby to Python

Step 1: Setting Up Your Environment

To start converting Ruby code to Python, you need a suitable development environment for Python:

  1. Install Python: Download and install Python from the official website.
  2. IDE Selection: Use an Integrated Development Environment (IDE) like VSCode or PyCharm, which supports Python.

Step 2: Translating Basic Syntax

Let’s begin by translating simple constructs like variables, loops, and conditionals.


In Ruby:

name = "John"
age = 30

In Python:

name = "John"
age = 30

The syntax is almost identical, but remember Python's strong emphasis on readability.



for i in (1..5)
  puts i


for i in range(1, 6):

Notice how Python uses range() and indentation rather than end.

Step 3: Converting Methods and Functions

Methods in Ruby:

def greet(name)
  "Hello, #{name}"

puts greet("Alice")

Functions in Python:

def greet(name):
    return f"Hello, {name}"


Python uses the def keyword just like Ruby but includes a colon (:) and follows precise indentation rules.

Step 4: Handling Classes and Objects

Ruby's class structure:

class Person
  def initialize(name, age)
    @name = name
    @age = age

  def introduce
    "Hi, my name is #{@name} and I am #{@age} years old."

person ="John", 30)
puts person.introduce

Python's class structure:

class Person:
    def __init__(self, name, age): = name
        self.age = age

    def introduce(self):
        return f"Hi, my name is {} and I am {self.age} years old."

person = Person("John", 30)

Python uses self to refer to instance variables and methods, and instead of new, it directly calls the class with its parameters.

Step 5: Managing Libraries and Modules

Ruby imports libraries using require, while Python uses import.

In Ruby:

require 'json'
data = JSON.parse('{"name": "John", "age": 30}')

In Python:

import json
data = json.loads('{"name": "John", "age": 30}')

Step 6: Exception Handling

Exception handling in Ruby:

  # Code that might raise an exception
rescue StandardError => e
  puts e.message

Exception handling in Python:

    # Code that might raise an exception
except Exception as e:

Step 7: Highlighting Advanced Concepts

Lambda Functions


add = ->(a, b) { a + b }
puts, 3)


add = lambda a, b: a + b
print(add(5, 3))

List Comprehensions

Ruby’s equivalent of a list comprehension:

array = [1, 2, 3, 4, 5]
squares = { |num| num ** 2 }

Python's list comprehension:

array = [1, 2, 3, 4, 5]
squares = [num ** 2 for num in array]


Converting code from Ruby to Python involves understanding both the syntactical and philosophical differences between the languages. By following this guide, you can methodically translate your Ruby constructs into their Pythonic counterparts, ensuring that your code remains efficient and readable.
