if age >= 18:
print("Eligible")
❌ Incorrect Indentation
if age >= 18:
print("Eligible")
Python requires proper indentation.
Correct:
if age >= 18:
print("Eligible")
🔹 11. Real-World Data Science Example
prediction = 0.82
if prediction >= 0.5:
print("Spam Email")
else:
print("Not Spam")
Many Machine Learning classification models use similar logic to convert prediction probabilities into categories.
🎯 Practice Questions
1. Check whether a number is positive or negative.
2. Check whether a person is eligible to vote.
3. Create a grading system using "if...elif...else".
4. Check whether a number is even or odd.
5. Determine the largest of three numbers.
🎯 Key Takeaways
✅ Use "if" to execute code when a condition is True.
✅ Use "else" to execute code when the condition is False.
✅ Use "elif" to check multiple conditions.
✅ Nested "if" statements allow more complex decision-making.
✅ Logical operators (and, or, not) help combine conditions.
✅ The ternary operator provides a concise way to write simple "if...else" statements.
Conditional statements are the foundation of decision-making in Python and are widely used in automation, data analysis, machine learning, and AI applications.

📘 Phase 1: Programming Fundamentals
🐍 Topic 4: Python Conditional Statements (if, elif, else)
Welcome back! 👋
In the previous lesson, you learned how to take input from users and display output. Now it's time to learn how Python makes decisions.
Conditional statements allow a program to execute different blocks of code based on whether a condition is True or False.
They are one of the most important concepts in Python and are used extensively in Data Science, Machine Learning, and real-world applications.
🔹 1. What are Conditional Statements?
Conditional statements help Python decide which code should run based on a condition.
Think of it like making everyday decisions:
• If it's raining → Carry an umbrella.
• Else → Wear sunglasses.
Similarly, Python checks a condition and decides what to execute.
🔹 2. The "if" Statement
The "if" statement executes a block of code only if the condition is True.
Syntax
if condition:
# Code to execute
Example
age = 20
if age >= 18:
print("Eligible to vote")
Output
Eligible to vote
🔹 3. The "if...else" Statement
Use "else" when you want to execute another block if the condition is False.
Example
age = 16
if age >= 18:
print("Eligible to vote")
else:
print("Not eligible to vote")
Output
Not eligible to vote
🔹 4. The "if...elif...else" Statement ⭐
Use "elif" when you need to check multiple conditions.
Example
marks = 85
if marks >= 90:
print("Grade A")
elif marks >= 75:
print("Grade B")
elif marks >= 60:
print("Grade C")
else:
print("Grade D")
Output
Grade B
Python checks conditions from top to bottom and executes the first condition that is True.
🔹 5. Nested "if" Statements
You can place one "if" statement inside another.
Example
age = 25
citizen = True
if age >= 18:
if citizen:
print("Eligible to vote")
Output
Eligible to vote
🔹 6. Using Logical Operators
Conditional statements often use logical operators.
"and"
age = 25
if age >= 18 and age <= 60:
print("Working Age")
"or"
marks = 35
if marks >= 40 or marks == 35:
print("Eligible for Grace Marks")
"not"
is_holiday = False
if not is_holiday:
print("Go to Office")
🔹 7. Checking Multiple Conditions
salary = 60000
experience = 4
if salary > 50000 and experience >= 3:
print("Eligible for Promotion")
else:
print("Not Eligible")
🔹 8. Ternary Operator ⭐
A shorter way to write an "if...else" statement.
Syntax
value_if_true if condition else value_if_false
Example
age = 20
status = "Adult" if age >= 18 else "Minor"
print(status)
Output
Adult
🔹 9. Real-World Example
temperature = 38
if temperature > 35:
print("It's a hot day.")
elif temperature >= 20:
print("Weather is pleasant.")
else:
print("It's cold.")
🔹 10. Common Mistakes
❌ Missing Colon
if age >= 18
print("Eligible")
This gives a SyntaxError.

📘 Phase 1: Programming Fundamentals
🐍 Topic 3: Python Input & Output
In the previous lesson, you learned about Python Operators. Now it's time to learn how Python interacts with users by taking input and displaying output.
Input and Output (I/O) are fundamental concepts because almost every real-world program accepts input, processes it, and produces meaningful output.
🔹 1. What is Input & Output?
A Python program generally follows three steps:
Input → Process → Output
Example:
• User enters two numbers Input
• Python adds them Process
• Sum is displayed Output
🔹 2. Displaying Output
Python uses the print() function to display information on the screen.
Example
print("Hello, Data Science!")
Output
Hello, Data Science!
🔹 3. Printing Variables
You can print variables along with text.
name = "Deepak"
print(name)
Output:
Deepak
Or:
name = "Deepak"
print("Welcome", name)
Output:
Welcome Deepak
🔹 4. Taking User Input
Python uses the input() function to receive input from users.
name = input("Enter your name: ")
print("Hello", name)
Example Output:
Enter your name: Deepak
Hello Deepak
🔹 5. Important Note ⭐
The input() function always returns a string, even if the user enters a number.
age = input("Enter age: ")
print(type(age))
Output:
<class 'str'>
🔹 6. Converting Input to Integer
To perform mathematical operations, convert the input using int().
age = int(input("Enter your age: "))
print(age + 5)
Example:
Enter your age: 25
30
🔹 7. Taking Decimal Input
Use float() for decimal numbers.
price = float(input("Enter price: "))
print(price)
🔹 8. Taking Multiple Inputs
You can take multiple inputs in a single line.
name, city = input("Enter your name and city: ").split()
print(name)
print(city)
Example Input:
Deepak Mumbai
Output:
Deepak
Mumbai
🔹 9. Formatting Output
Using f-Strings ⭐ Recommended
name = "Deepak"
age = 25
print(f"My name is {name} and I am {age} years old.")
Output:
My name is Deepak and I am 25 years old.
Using .format()
name = "Deepak"
print("Welcome {}".format(name))
🔹 10. Example Program
name = input("Enter your name: ")
age = int(input("Enter your age: "))
print(f"Hello {name}")
print(f"Next year you will be {age + 1} years old.")
Example Output:
Enter your name: Deepak
Enter your age: 25
Hello Deepak
Next year you will be 26 years old.
🔹 11. Common Mistake
num1 = input("Enter first number: ")
num2 = input("Enter second number: ")
print(num1 + num2)
Input:
10
20
Output:
1020
Why?
Because both values are strings.

📘 Phase 1: Programming Fundamentals
🐍 Topic 2: Python Operators
In the previous lesson, you learned about Variables & Data Types. Now it's time to learn how Python performs calculations, comparisons, and logical operations using operators.
Operators are one of the most fundamental concepts in Python. You'll use them in almost every program, from simple calculations to complex Machine Learning algorithms.
🔹 1. What are Operators?
Operators are special symbols used to perform operations on variables and values.
Example:
a = 10
b = 5
print(a + b)
Output:
15
Here, "+" is an operator that adds two numbers.
🔹 2. Types of Operators in Python
Python has several types of operators:
✅ Arithmetic Operators
✅ Comparison Operators
✅ Assignment Operators
✅ Logical Operators
✅ Membership Operators
✅ Identity Operators
🔹 3. Arithmetic Operators ⭐
Used for mathematical calculations.
Operators:
• ** + Addition**: 10 + 5 = 15
• - Subtraction: 10 - 5 = 5
• ** Multiplication*: 10 * 5 = 50
• / Division: 10 / 5 = 2.0
• // Floor Division: 10 // 3 = 3
• % Modulus (Remainder): 10 % 3 = 1
• ** Exponent: 2 ** 3 = 8
Example:
a = 10
b = 3
print(a + b)
print(a - b)
print(a * b)
print(a / b)
print(a // b)
print(a % b)
print(a ** b)
🔹 4. Comparison Operators ⭐
Used to compare two values. The result is always True or False.
Operators:
• == Equal to
• != Not Equal to
• > Greater than
• < Less than
• >= Greater than or Equal to
• <= Less than or Equal to
Example:
x = 20
y = 10
print(x > y)
print(x == y)
print(x != y)
Output:
True
False
True
🔹 5. Assignment Operators
Used to assign values to variables.
x = 10
x += 5
print(x)
Output:
15
Other assignment operators:
x -= 2
x *= 3
x /= 2
🔹 6. Logical Operators ⭐
Used to combine multiple conditions.
and
Returns True only if both conditions are True.
age = 25
print(age > 18 and age < 30)
Output:
True
or
Returns True if at least one condition is True.
print(age < 18 or age < 30)
Output:
True
not
Reverses the result.
print(not(age > 18))
Output:
False
🔹 7. Membership Operators
Used to check whether a value exists in a sequence.
in
fruits = ["Apple", "Banana", "Mango"]
print("Apple" in fruits)
Output:
True
not in
print("Orange" not in fruits)
Output:
True
🔹 8. Identity Operators
Used to check whether two variables refer to the same object.
is
a = [1, 2]
b = a
print(a is b)
Output:
True
is not
x = [1, 2]
y = [1, 2]
print(x is not y)
Output:
True
🔹 9. Operator Precedence
Python follows the PEMDAS/BODMAS rule while evaluating expressions.

| 20 | GigaChat 3.5 Ultra Publicly Released — The New Generation of the Flagship Model
The GigaChat team has released GigaChat 3.5 Ultra as open source—a new 432B model under the MIT license. This is the first open-source hybrid of GatedDeltaNet and MLA scaled to hundreds of billions of parameters, featuring a proprietary training recipe we refined through more than 1,500 experiments. The model has grown in terms of code, mathematics, agent scenarios, and application domains—yet it’s 40% smaller than GigaChat 3.1 Ultra.
What’s inside:
🔘A proprietary hybrid MLA + Gated DeltaNet architecture with a dedicated stabilization framework, without which this hybrid setup would not train reliably at this scale;
🔘 Gated Attention: the model can locally down-weight overly strong signals from the attention layer;
🔘GatedNorm: normalization with an explicit gate that controls signal magnitude across features;
🔘Approximately 4x lower KV cache per token: with the same memory budget, the model can support 2.14x longer context and deliver a 20% throughput increase under load;
🔘Two MTP heads, enabling up to 2.2x faster generation;
🔘FP8 across all training stages with no quality degradation compared with bf16, enabled by custom Triton and CUDA kernels;
🔘A new online RL stage after SFT and DPO.
Results:
🔘 GigaChat-3.5-Ultra-Base outperforms DeepSeek V3.2 Exp Base and DeepSeek V4 Flash Base on average across a set of general, math, and code benchmarks:
🔘 GigaChat-3.5-Ultra-Instruct is comparable to DeepSeek V3.2 in terms of average score, despite having half the size;
🔘 According to the MiniMax-M2.7 LLM judge, the average win rate against GigaChat 3.1 Ultra is 75.9%, and against GPT-5 is 68.7%.
The entire stack — data (our own LLM-filtered Common Crawl, 600+ programming languages in the code), architecture, training methodology, and infrastructure — was built end-to-end by GigaChat team.
