🎯 Learning Objectives

By the end of this lesson, learners will be able to:

  • Define what a variable is in Python

  • Create and assign values to variables

  • Follow Python’s naming rules and best practices

  • Understand the concept of dynamic typing

📚 Lesson Content

🔹 What is a Variable?

A variable in Python is a named container that stores data.
You can assign a value to a variable using the equals sign (=).

🧑‍💻 Example:
python
name = "Krishna"
age = 25

Here:

  • name is a variable storing a string

  • age is a variable storing an integer

🔸 How Python Handles Variables

  • Python is dynamically typed, which means you don’t need to declare the type — Python figures it out for you.

  • A variable’s type is assigned automatically at runtime.

🧠 Example:
python
x = 10 # Integer
x = "Hello" # Now it's a string!

✅ Python allows reassigning a variable with a different data type.

🔸 Variable Naming Rules (Syntax)

  • Must start with a letter or an underscore (_)

  • Cannot start with a number

  • Can only contain letters, numbers, and underscores

  • Case-sensitive (Age ≠ age)

✅ Valid Names:
python
user_name = "Anaya"
_user1 = 23
❌ Invalid Names:
python
1user = "wrong" # starts with a number
user-name = "wrong" # contains a hyphen

💡 Best Practices

  • Use descriptive names: user_age, total_price

  • Use snake_case: lowercase with underscores for multi-word variables

🔧 Practical Examples

python
student_name = "Poorva"
student_age = 8
is_kid = True

print("Name:", student_name)
print("Age:", student_age)
print("Is Kid:", is_kid)

📝 Assignment / Activity

  1. Create three variables:

    • Your name

    • Your age

    • A Boolean that says if you’re a student

  2. Print all three using the print() function

❓ Common Mistakes

Mistake Why it’s wrong
2name = "Amit" Starts with a number
first name = "Radha" Contains a space
Print("hello") Python is case-sensitive: should be print

🧠 Reflection Question

What happens if you reassign a variable multiple times?
Try:

python
x = 5
x = "five"
print(x)
