Say I have
text = "El próximo AÑO, vamos a salir a Curaçao... :@ :) será el día #MIÉRCOLES 30!!!!"
How can I turn it into
text2 = "El próximo AÑO vamos a salir a Curaçao será el día MIÉRCOLES 30"
Using regex?

You can try using the \W character class:
re.sub(r'\W+', ' ', text)

1@NicolasVega What version of Python are you using? And on what platform? – blhsing Oct 09 '18 at 01:18

Good point @blhsing. I'm sorry it didn't work for you, Nicolas... It worked for me on Python 3 but it does not work on Python 2.7. We'll have to handle Unicode. – Carlos Mermingas Oct 09 '18 at 01:24

1For python2.7 you can modify it to: `re.sub(re.compile(r'\W+',re.UNICODE), ' ', text)` – Sohaib Farooqi Oct 09 '18 at 05:07

If you need compatibility with Python 2.7 you can use the str.isalpha() method:
# -*- coding: utf-8 -*-
import re
text = u"El próximo AÑO, vamos a salir a Curaçao... :@ :) será el día #MIÉRCOLES 30!!!!"
print(re.sub(' +', ' ', ''.join(c for c in text if c.isalpha() or c.isdigit() or c.isspace())))
This outputs:
El próximo AÑO vamos a salir a Curaçao será el día MIÉRCOLES 30

One last question... What if I wanted "Vamos en la ruta Bogotá-Medellín" to become "Vamos en la ruta Bogotá Medellín"? – NicolasVega Oct 09 '18 at 03:21

In that case `print(re.sub(' +', ' ', ''.join(c if c.isalpha() or c.isdigit() or c.isspace() else ' ' for c in text)).strip())` will do. – blhsing Oct 09 '18 at 03:27
