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 .
Python:
def greet(name):print(f'Hello, {name}!')
Erlang:
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.
Python:
person = {'name': 'John', 'age': 30}
Erlang:
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.
Python:
import threading
def print_numbers():
for i in range(10):
print(i)
threading.Thread(target=print_numbers).start()
Erlang:
-module(examples).-export([threaded_count_to_ten/0]).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!
