Aprende Writing Pythonic Code | Pythonic Best Practices

Writing Pythonic code means using the idioms and features that make Python unique, expressive, and readable.

Pythonic code favors clarity, simplicity, and the use of the language's built-in capabilities. Instead of translating code patterns from other languages, you should take advantage of Python's expressive syntax and standard library.

Key Pythonic techniques include:

Using list comprehensions for concise looping and filtering;
Applying unpacking to assign multiple variables at once;
Leveraging built-in functions such as map, filter, any, all, and sum to perform common tasks efficiently.

Employing these constructs makes your code cleaner, more efficient, and easier to understand for other Python developers.

# Non-Pythonic approach: using loops and manual accumulation
numbers = [1, 2, 3, 4, 5]
squares = []
for n in numbers:
    squares.append(n * n)
even_squares = []
for s in squares:
    if s % 2 == 0:
        even_squares.append(s)
print("Even squares (non-Pythonic):", even_squares)

# Pythonic approach: using list comprehensions and built-in functions
numbers = [1, 2, 3, 4, 5]
squares = [n * n for n in numbers]
even_squares = [s for s in squares if s % 2 == 0]
print("Even squares (Pythonic):", even_squares)

# Unpacking example (Pythonic)
point = (3, 4)
x, y = point
print(f"Coordinates: x={x}, y={y}")

# Using built-in functions (Pythonic)
total = sum(numbers)
print("Sum of numbers:", total)
