Mastering the Shift: 3 Tips to Transition from Python to Erlang


Shifting from Python to Erlang can feel like learning to write with your non-dominant hand. But fear not! With a few tricks up your sleeve, the transition can be smoother. Here are three quick tips to help you navigate from Python to Erlang more easily.  Here are 3 tips help you transition from Python to Erlang.

Tip 1: Understanding Syntax Basics

Python uses whitespace to delineate code blocks, while Erlang punctuation like ; , and .


def greet(name): 
    print(f'Hello, {name}!')


greet(Name) -> io:fwrite("Hello, ~p!", [Name]).

Tip 2: Getting to Grips with Data Structures

In Python, lists and dictionaries are the most commonly used data structures. Erlang, on the other hand, doesn't have a built-in dictionary data type. Instead, Erlang developers often use key-value lists, maps, or records for similar purposes.


person = {'name': 'John', 'age': 30}


Person = #{name => 'John', age => 30}.

Tip 3: Mastering Concurrency

Erlang was designed with concurrency in mind. While Python threads are subject to the Global Interpreter Lock (GIL), Erlang's lightweight processes are not.


import threading  
def print_numbers(): 
    for i in range(10): 



threaded_count_to_ten() -> 
  spawn(fun () -> 
    lists:foreach(fun(I) -> 
      io:fwrite("~p~n", [I]) end, lists:seq(1, 10)) end).

These are just a few tips to help you transition from Python to Erlang. As you delve deeper into Erlang, you'll discover more nuances, but remember: the key is to keep practicing and experimenting. Happy coding!
