A compact Python cheatsheet that revisits the fundamentals of the language in less than 20 lines of code.
It covers variables, data structures, conditionals, loops, functions, and classes — all in a minimal and beginner-friendly format.

# Variables and types
name, age, active = "Python", 30, True

# Structures
fruits = ["apple", "banana"]
user = {"name": "Ana", "age": 25}

# Conditional
print("Adult" if age >= 18 else "Minor")

# For loop
for f in fruits: print(f)

# While loop
c = 0
while c < 2: print("Loop", c); c += 1

# Function
def add(a, b=0): return a + b
print(add(5, 3))

# Class
class Person:
    def __init__(self, name): self.name = name
    def speak(self): print(f"I am {self.name}")

Person("John").speak()

• Variables, strings, numbers, booleans
• Lists and dictionaries
• If/else conditionals
• For and while loops
• Functions with default arguments
• A simple class (OOP basics)

• Perfect for beginners as a quick overview
• Great for revision before interviews
• A fun challenge: learn Python’s core in 20 lines only

After mastering these basics, try exploring:

• File handling (open, read, write)
• Popular libraries like pandas, numpy, and requests
• Best practices for writing clean and maintainable code
