**Day 3: Variables and Data Types**

**Variables**:- Understand the concept of variables as containers for storing data.
- Learn how to assign values to variables using the assignment operator
`=`

. **Data Types**:- Introduce fundamental data types in Python:
**Integer (int)**: Whole numbers, e.g., 5, -10.**Float (float)**: Numbers with decimal points, e.g., 3.14, -0.5.**String (str)**: Sequences of characters enclosed in single or double quotes, e.g., “Hello, Python!”.**Boolean (bool)**: Represents either`True`

or`False`

.

**Variable Naming Rules**:- Explain the rules for naming variables:
- Variable names must start with a letter (a-z, A-Z) or an underscore (_).
- Subsequent characters can include letters, numbers, and underscores.
- Variable names are case-sensitive (e.g.,
`myVar`

and`myvar`

are different).

**Assigning Values**:- Demonstrate how to assign values to variables:

`python my_integer = 5 my_float = 3.14 my_string = "Hello, Python!" is_true = True`

**Day 4: Basic Operations with Data Types**

**Arithmetic Operations**:- Introduce basic arithmetic operations:
- Addition (
`+`

), subtraction (`-`

), multiplication (`*`

), division (`/`

), and exponentiation (`**`

).

- Addition (
- Show how to perform these operations with integers and floats.
**String Operations**:- Explain string concatenation using the
`+`

operator:`greeting = "Hello" name = "Alice" message = greeting + ", " + name + "!"`

**Type Conversion**:- Discuss type conversion between data types (casting):
`int()`

,`float()`

, and`str()`

functions.- Example:
`int("5")`

converts the string “5” to an integer.

**String Methods**:- Introduce some basic string methods:
`len()`

: Returns the length of a string.`upper()`

: Converts a string to uppercase.`lower()`

: Converts a string to lowercase.- Example:
`len("Python")`

,`"Hello".upper()`

,`"WORLD".lower()`

.

**Boolean Operations**:- Cover basic boolean operations:
`and`

,`or`

, and`not`

.- Example:
`True and False`

,`True or False`

,`not True`

.

**Practice Exercises**:- Provide exercises for students to practice using variables and performing operations with data types.

By the end of Day 4, you should have a solid understanding of variables and the basic data types in Python. You’ll also be comfortable performing basic operations on these data types, which is essential for programming in Python.
