2.1 PEP 20 – The Zen of Python The Zen of Python is a collection of 19 aphorisms, which reflect the philosophy behind Python, its guiding principles, and design. Tim Peters, a long time major contributor to the Python programming language and Python community, wrote this 19-line poem on the Python mailing list in 1999, and it became entry #20 in the Python Enhancement Proposals in 2004.

4.1 PEP 257 – Docstring Conventions What is PEP 257? PEP 257 is a document created as part of the Python Developer's Guide, which makes an attempt to standardize the high-level structure of docstrings. It outlines the conventions, best practices, and semantics (not laws or regulations!) associated with documenting Python code using docstrings. In short, it tries to answer the following two questions:

Cómo las computadoras entienden los caracteres individuales

Has escrito algunos programas interesantes desde que comenzó este curso, pero todos ellos han procesado solo un tipo de datos: los numéricos. Como sabes (puedes ver esto en todas partes), muchos datos de la computadora no son números: nombres, apellidos, direcciones, títulos, poemas, documentos científicos, correos electrónicos, sentencias judiciales, confesiones de amor y mucho, mucho más.

Errores, fallas y otras plagas

import math

x = float(input("Ingresa x: "))
y = math.sqrt(x)

print("La raíz cuadrada de", x, "es igual a", y)
