Create interactive Python tutorials

Here’s a detailed interactive Python tutorial structured as a multi-part text-based series. Each section is progressive, focusing on different core Python concepts with interactive exercises that learners can run in any Python environment (e.g., Jupyter Notebook, online IDEs like Replit, or directly in the terminal).

Python Tutorial: Beginner to Intermediate

---

🧱 Part 1: Introduction to Python & Variables

Concepts Covered:

• Printing to the console

• Comments

• Variables and data types (int, float, str, bool)

python
CopyEdit
# This is a comment
print("Hello, Python!")

# Variables
name = "Alice"
age = 25
height = 5.6
is_student = True

# Displaying variable types
print(type(name), type(age), type(height), type(is_student))

Try it Yourself:

• Change the name, age, and height values.

• Add another variable for city.

---

🔢 Part 2: Arithmetic and String Operations

Concepts Covered:

• Basic arithmetic

• Order of operations

• String concatenation and repetition

python
CopyEdit
# Arithmetic
a = 10
b = 3
print("Addition:", a + b)
print("Division:", a / b)
print("Power:", a ** b)

# String operations
first = "Python"
second = "Rocks"
print(first + " " + second)
print(first * 3)

Try it Yourself:

• Add modulus operation.

• Try different types of strings and see how * behaves.

---

🔁 Part 3: Conditionals and Control Flow

Concepts Covered:

• if, elif, else

• comparison and logical operators

python
CopyEdit
score = 85

if score >= 90:
    print("Grade: A")
elif score >= 75:
    print("Grade: B")
else:
    print("Grade: C")

# Logical operators
has_passed = score >= 60
is_honors = score >= 90
print("Passed:", has_passed and not is_honors)

Try it Yourself:

• Add more grading conditions.

• Test with different scores.

---

🔄 Part 4: Loops

Concepts Covered:

• for and while loops

• range()

• Loop control: break, continue

python
CopyEdit
# For loop
for i in range(5):
    print("Count:", i)

# While loop
x = 0
while x < 3:
    print("x is", x)
    x += 1

# Loop control
for num in range(10):
    if num == 5:
        continue
    if num == 8:
        break
    print(num)

Try it Yourself:

• Modify ranges and conditions.

• Try printing even numbers only.

---

🧰 Part 5: Functions

Concepts Covered:

• Defining functions

• Parameters and return values

• Default arguments

python
CopyEdit
def greet(name="Friend"):
    return f"Hello, {name}!"

print(greet("Bob"))
print(greet())

# Function with multiple parameters
def add(x, y):
    return x + y

print(add(5, 3))

Try it Yourself:

• Add a function that multiplies three numbers.

• Use return values in another function.

---

📦 Part 6: Lists and Tuples

Concepts Covered:

• Creating and modifying lists

• Indexing and slicing

• Tuple immutability

python
CopyEdit
# Lists
fruits = ["apple", "banana", "cherry"]
fruits.append("date")
fruits[1] = "blueberry"
print(fruits)

# Tuples
dimensions = (1920, 1080)
print("Width:", dimensions[0])

Try it Yourself:

• Remove an item from the list.

• Try to change a tuple value and observe the error.

---

🧮 Part 7: Dictionaries and Sets

Concepts Covered:

• Key-value pairs

• Access and update values

• Set uniqueness

python
CopyEdit
# Dictionary
person = {"name": "Alice", "age": 30}
person["age"] = 31
person["city"] = "New York"
print(person)

# Set
numbers = {1, 2, 2, 3, 4}
print(numbers)

Try it Yourself:

• Add new keys to the dictionary.

• Combine two sets using union.

---

🧱 Part 8: Error Handling

Concepts Covered:

• try, except

• finally block

• Common exceptions

python
CopyEdit
try:
    num = int(input("Enter a number: "))
    print(10 / num)
except ZeroDivisionError:
    print("You can't divide by zero!")
except ValueError:
    print("Please enter a valid number.")
finally:
    print("Done.")

Try it Yourself:

• Trigger both exceptions.

• Add a custom message in the finally block.

---

🗃️ Part 9: File Handling

Concepts Covered:

• Reading and writing files

• File modes

• Using with for resource management

python
CopyEdit
# Writing to a file
with open("demo.txt", "w") as f:
    f.write("Hello from Python!n")

# Reading from a file
with open("demo.txt", "r") as f:
    content = f.read()
    print(content)

Try it Yourself:

• Append a new line.

• Count the number of lines in the file.

---

🧑‍💻 Part 10: Classes and Objects

Concepts Covered:

• Object-oriented programming

• Class, __init__, methods

• Inheritance

python
CopyEdit
class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def greet(self):
        print(f"Hi, I'm {self.name} and I'm {self.age} years old.")

p1 = Person("Eve", 28)
p1.greet()

# Inheritance
class Student(Person):
    def __init__(self, name, age, grade):
        super().__init__(name, age)
        self.grade = grade

s1 = Student("Tom", 20, "A")
print(s1.grade)

Try it Yourself:

• Add a method that increases the age.

• Create a new class called Teacher.
