Day 4 - Data Types in Python

🐍 Day 4 — Data Types in Python

In Python, every value has a data type. Data types tell Python what kind of data it is working with.

Here are some of the most common beginner-friendly types:
🔹 1. String (str)
Used for text

name = "Alice"

🔹 2. Integer (int)
Whole numbers

age = 20

🔹 3. Float (float)
Decimal numbers

pi = 3.14

🔹 4. Boolean (bool)
True or False values

is_student = True

🔹 5. None Type
Represents no value

data = None

💡 Why Data Types Matter?

✔ Helps Python understand how to store and operate on data
✔ Enables validation, calculations, decisions, and formatting
✔ Makes your code logical and predictable

🧩 Mini Task

Create variables using at least 3 different data types and print them out.

📍Day 5 — User Input in Python

Today we learn how programs interact with people!
The input() function allows users to enter data while the program is running.

🧩 How it Works

name = input("Enter your name: ")
print("Hello", name)

When you run this, Python waits for the user to type something.

🔍 Important Point

Everything entered through input() is treated as text (string) by default.

So if you need numbers, you must convert them:

age = int(input("Enter your age: "))
print(age + 1)

🌟 Why User Input Matters

It helps you create dynamic programs like:
✔️ calculators
✔️ login systems
✔️ forms
✔️ interactive chatbots (👀 like the one you're learning to build someday)

📝 Mini Task

Ask the user for:

their name
their age
their country

Then print a sentence combining all three.

🐍 Day 6 — Type Conversion (Casting) in Python

When you receive input from users or work with different data types, sometimes you need to convert values — for example, from text to numbers.

This process is called type conversion or casting.

🔧 Common Conversions

int()

→ converts to integer

float()

→ converts to decimal number

str()

→ converts to string

bool()

→ converts to True/False

✔ Example

age = int(input("Enter your age: "))
print(age + 1)

Here, input() gives a string, so we convert it using int() to do math.

⚠ Important
If the value cannot be converted (e.g., "hello" → int()), Python will raise an error.

📌 Where Casting is Useful?
✔ user input
✔ math operations
✔ formatting text
✔ APIs & databases
✔ data analysis

🧩 Mini Task

Ask for two numbers using input() and print their sum.

Tip: Convert them first 😉

🐍 Day 7 — Operators in Python

Operators allow Python to perform actions such as calculations, comparisons, and logic-based decisions.

🔸 1. Arithmetic Operators

Used for math

+   -   *   /   %   **   //

Example:

x = 10
y = 3
print(x + y)   # 13

🔸 2. Comparison Operators

Used to compare values (returns True/False)

==   !=   >   <   >=   <=

Example:

print(5 > 2)   # True

🔸 3. Logical Operators

Used for conditions and decision-making

and   or   not

Example:

print(True and False)  # False

🧩 Mini Task

Ask the user for two numbers and print:

✔️ their sum
✔️ which one is greater

🐍 Day 8 — Conditional Statements in Python

Conditional statements allow your program to make decisions based on conditions.

🔹 Basic If Statement
age = 18
if age >= 18:
print("You are an adult")

🔹 If–Else Statement

if age >= 18:
print("Adult")
else:
print("Minor")

🔹 If–Elif–Else

score = 85
if score >= 90:
print("A")
elif score >= 80:
print("B")
else:
print("C or below")

💡 Why It Matters

Conditional logic powers real-world systems like:
✔ login validation
✔ access control
✔ grading systems
✔ navigation & decision bots
✔ games & AI logic

🧩 Mini Task

Ask the user for a number and:
✔ print if it’s positive, negative, or zero.
