BASIC LEVEL - STEP 4

Introduction to Python (Optional, but Recommended)

Learn why Python is popular in AI and get started with basic Python programming concepts.

💡

This Step is Optional

While learning Python will greatly enhance your AI journey, you can continue with the next steps if you prefer to focus on AI concepts first. You can always come back to learn Python later when you're ready for hands-on coding.

Why Python for AI?

📚 Easy to Learn

Python's syntax is close to natural English, making it beginner-friendly and readable.

🛠️ Rich Libraries

Extensive libraries like TensorFlow, PyTorch, and scikit-learn make AI development easier.

👥 Large Community

Huge community support with tutorials, documentation, and help when you get stuck.

🏢 Industry Standard

Used by major tech companies like Google, Netflix, and Tesla for AI and data science.

Python Basics You'll Need

Variables and Data Types

# Variables store data
name = "Alice" # String (text)
age = 25 # Integer (whole number)
height = 5.6 # Float (decimal number)
is_student = True # Boolean (True/False)

Lists and Loops

# Lists store multiple items
fruits = ["apple", "banana", "orange"]
# Loop through the list
for fruit in fruits:
print(f"I like {fruit}")

Functions

# Functions are reusable blocks of code
def greet(name):
return f"Hello, {name}!"
message = greet("Alice")
print(message) # Output: Hello, Alice!
