Python Programming & AI Resources

Python in High School Arnaud Rodin, 2020

Tune in to the 10th AI Journey 2025 international conference: scientists, visionaries, and global AI practitioners will come together on one stage. Here, you will hear the voices of those who don't just believe in the future—they are creating it! Speakers include visionaries Kai-Fu Lee and Chen Qufan, as well as dozens of global AI gurus! Do you agree with their predictions about AI? On November 20, we will focus on the role of AI in business and economic development and present technologies that will help businesses and developers be more effective by unlocking human potential. On November 21, we will talk about how engineers and scientists are making scientific and technological breakthroughs and creating the future today! The day's program includes presentations by scientists from around the world: - Ajit Abraham (Sai University, India) will present on “Generative AI in Healthcare” - Nebojša Bačanin Džakula (Singidunum University, Serbia) will talk about the latest advances in bio-inspired metaheuristics - AIexandre Ferreira Ramos (University of São Paulo, Brazil) will present his work on using thermodynamic models to study the regulatory logic of transcriptional control at the DNA level - Anderson Rocha (University of Campinas, Brazil) will give a presentation entitled “AI in the New Era: From Basics to Trends, Opportunities, and Global Cooperation”. And in the special AIJ Junior track, we will talk about how AI helps us learn, create and ride the wave with AI. The day will conclude with an award ceremony for the winners of the AI Challenge for aspiring data scientists and the AIJ Contest for experienced AI specialists. The results of an open selection of AIJ Science research papers will be announced. Ride the wave with AI into the future! Tune in to the AI Journey webcast on November 19-21.

✅ Python Basics: Variables & Data Types 🐍📚 🔹 What is a Variable? A variable is a name that stores some value. Think of it like a container that holds data.

x = 10
name = "Alice"

Here: ⦁ x is a variable storing a number ⦁ name is storing text Variables let you reuse values, perform calculations, or manipulate text later in your code. 🔹 Python Rules for Naming Variables ✔ Must start with a letter or underscore (_) ✔ Can contain letters, numbers, and underscores ❌ No spaces or special characters ❌ Can't start with a number ❌ Avoid using keywords like if, while, class Examples:

age = 25      # valid  
_name = "Raj" # valid  
2num = 4      # ❌ invalid  

🔹 Data Types in Python Python automatically assigns a data type based on the value. 1️⃣ Integer → int Whole numbers

x = 5

2️⃣ Float → float Decimal numbers

pi = 3.14

3️⃣ String → str Text in quotes

name = "Sara"

4️⃣ Boolean → bool True or False

is_happy = True

5️⃣ NoneType → None No value

empty = None

🔹 How to Check Data Type? Use the type() function:

print(type(name))  # <class 'str'>
print(type(x))     # <class 'int'>

🔹 Changing or Reassigning Variables

x = 10
x = x + 5  # Now x is 15

You can also change the data type:

x = 100
x = "one hundred"   # Now x is a string

✅ Quick Practice:

a = 3
b = "hello"
c = 5.5
d = True

print(type(a))
print(type(b))
print(type(c))
print(type(d))

💡 Tip: Python is dynamically typed – you don't need to declare the type. React ❤️ for more!
