Python Code Examples

Try these common Python patterns:

Data Processing

# List comprehension
numbers = [1, 2, 3, 4, 5]
squared = [x**2 for x in numbers]
print(squared)  # [1, 4, 9, 16, 25]

# Dictionary operations
data = {"name": "Python", "version": 3.12}
for key, value in data.items():
    print(f"{key}: {value}")

Functions and Classes

def calculate_fibonacci(n):
    if n <= 1:
        return n
    return calculate_fibonacci(n-1) + calculate_fibonacci(n-2)

class Calculator:
    def __init__(self):
        self.result = 0
    
    def add(self, value):
        self.result += value
        return self.result

calc = Calculator()
print(calc.add(10))  # 10
