PocketCode for Students: Learn to Code from Scratch

PocketCode for Students: Learn to Code from Scratch

Want to learn to code but don't have a PC? PocketCode is the perfect tool to get started. All you need is your Android phone.

Why PocketCode for learning?

• No PC needed — Your phone is enough
• Built-in AI — An assistant that explains code to you
• Multiple languages — Python, JavaScript, Java, C++, Rust and more
• Free — No hidden costs
• Real projects — Create functional apps, websites, and scripts

Your first program

Step 1: Install PocketCode

Download PocketCode from the Google Play Store and open the app.

Step 2: Create a project

1. Tap New Project
2. Name it: "My First Program"
3. Select the language: Python (recommended for beginners)
4. The project is created with a main.py file

Step 3: Write code

# My first Python program
name = input("What's your name? ")
print(f"Hello, {name}! Welcome to programming 🎉")

# Simple calculator
num1 = float(input("First number: "))
num2 = float(input("Second number: "))

print(f"Addition: {num1 + num2}")
print(f"Subtraction: {num1 - num2}")
print(f"Multiplication: {num1 * num2}")

if num2 != 0:
    print(f"Division: {num1 / num2}")
else:
    print("Cannot divide by zero")

Step 4: Run

Tap the ▶️ button to run. The output appears in the integrated terminal.

Basic concepts

Variables

Variables are containers that store information:

# Data types
name = "Ana"            # Text (string)
age = 17                # Whole number (int)
height = 1.65           # Decimal number (float)
is_student = True       # True/False (boolean)

Conditionals

Make decisions in your code:

grade = 8.5

if grade >= 9:
    print("Outstanding 🌟")
elif grade >= 7:
    print("Very Good 👍")
elif grade >= 5:
    print("Pass ✅")
else:
    print("Fail 📚")

Loops

Repeat actions:

# Multiplication table
number = 7

for i in range(1, 11):
    result = number * i
    print(f"{number} × {i} = {result}")

Functions

Organize your code into reusable blocks:

def calculate_circle_area(radius):
    pi = 3.14159
    area = pi * radius ** 2
    return round(area, 2)

# Use the function
radius = float(input("Circle radius: "))
area = calculate_circle_area(radius)
print(f"The area is: {area}")
