🧠 Phase 01: Variables & Data Types 🧱

"Memory allocated. Defining the building blocks of the system's logic."

This module covers the absolute fundamentals of storing and identifying information in MicroPython. Before we can manipulate hardware, we must understand how to store data in the system's memory.

🗃️ CORE DATA TYPES

In this chapter, we define variables and explore the primary data structures used in MicroPython:

• int: Integer numbers (whole numbers).
• float: Floating-point numbers (decimals).
• str: Strings (text and characters).
• list: Ordered, mutable arrays of items.
• dict: Dictionaries containing key-value pairs.

💻 THE SCRIPT (main.py)

Below is the code demonstrating how to assign these data types to variables and verify their types in the system.

# Integer assignment
a = 1
b = 2
print(type(a))

# Float assignment
c = 1.2
print(type(c))

# String assignment
name = "Rax"
print(type(name))

# List assignment (Array of strings)
list_of_names = ['Rakesh', 'Rim']
print(type(list_of_names))

# Dictionary assignment (Key-Value pairs)
dic_of_user = {
    'name': "Rakesh",
    'address': "Guptipara",
    'github': True 
}
print(type(dic_of_user))

🛠️ BUILT-IN FUNCTIONS USED

To inspect our data and output the results, we utilize two essential built-in Python functions in this script:

• print(): A function used to print or write data directly to the console/shell.
• type(): A function that evaluates the argument passed to it and returns the object name (class) of that specific data type.
