⚙️ Installing Python

Before writing code, you need Python installed on your system.

👉 Steps:

1. Go to the official Python website
2. Download Python
3. Install it and check:

python --version

If it shows a version, Python is installed successfully.

---

🧠 Your First Python Program

Let’s write your first program.

💻 Example:

print("Hello, World!")

📌 Output:

Hello, World!

👉 This command tells Python to display text on the screen.

---

🔢 Variables in Python

Variables are used to store data.

💻 Example:

name = "Rachel"
age = 20

👉 Here:

• name stores text
• age stores a number

---

📊 Data Types in Python

Python has different data types:

1. String (Text)

name = "Rachel"

2. Integer (Number)

age = 20

3. Float (Decimal)

price = 10.5

4. Boolean (True/False)

is_student = True

---

➕ Basic Operations

Python can perform calculations:

a = 10
b = 5

print(a + b)
print(a - b)
print(a * b)
print(a / b)

---

🔁 Conditional Statements in Python (Complete Guide)

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

---

🔹 1. if Statement

📖 Explanation

Executes code only if the condition is true.

💻 Example

age = 18

if age >= 18:
    print("You are eligible to vote")

---

🔹 2. if-else Statement

📖 Explanation

Executes one block if true, another if false.

💻 Example

age = 16

if age >= 18:
    print("You are an adult")
else:
    print("You are a minor")

---

🔹 3. if-elif-else Statement

📖 Explanation

Used when there are multiple conditions.

💻 Example

marks = 75

if marks >= 90:
    print("Grade A")
elif marks >= 75:
    print("Grade B")
elif marks >= 50:
    print("Grade C")
else:
    print("Fail")

---

🔹 4. Nested if Statement

📖 Explanation

An if statement inside another if.

💻 Example

age = 20
has_id = True

if age >= 18:
    if has_id:
        print("You can enter")
    else:
        print("ID required")
else:
    print("Not allowed")

---

🔹 5. Short-hand if (One-line if)

📖 Example

age = 20

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

---

🔹 6. Short-hand if-else (Ternary Operator)

📖 Example

age = 17

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

---

🔹 7. Logical Operators in Conditions

📖 Explanation

Used to combine conditions.

💻 Example

age = 25
has_license = True

if age >= 18 and has_license:
    print("You can drive")

---

🔄 Loops in Python (Complete Guide)

Loops are used to repeat a block of code multiple times.

---

🔹 1. for Loop

📖 Explanation

Used when you know how many times to repeat.

💻 Example

for i in range(5):
    print(i)

👉 Output:
0 1 2 3 4

---

🔹 2. Loop Through a List

fruits = ["apple", "banana", "mango"]

for fruit in fruits:
    print(fruit)

---

🔹 3. while Loop

📖 Explanation

Repeats as long as the condition is true.

💻 Example

i = 0

while i < 5:
    print(i)
    i += 1

---

🔹 4. break Statement

📖 Explanation

Stops the loop immediately.

💻 Example

for i in range(5):
    if i == 3:
        break
    print(i)

👉 Output:
0 1 2

---

🔹 5. continue Statement

📖 Explanation

Skips the current iteration.

💻 Example

for i in range(5):
    if i == 2:
        continue
    print(i)

👉 Output:
0 1 3 4

---

🔹 6. else with Loop

📖 Explanation

Runs after loop finishes normally.

💻 Example

for i in range(3):
    print(i)
else:
    print("Loop finished")

---

🔹 7. Nested Loops

📖 Explanation

Loop inside another loop.

💻 Example

for i in range(2):
    for j in range(3):
        print(i, j)

🧩 Lists in Python

📖 Explanation

A list is used to store multiple values in a single variable.

💻 Example

fruits = ["apple", "banana", "mango"]
print(fruits)

📌 Access Items

print(fruits[0])   # apple

📌 Modify List

fruits.append("orange")

💡 Why It Matters

Lists are used in almost every Python program to store and manage data.

---

🔤 Strings in Python

📖 Explanation

Strings represent text data.

💻 Example

name = "Rachel"
print(name)

 

print(name.upper())
print(name.lower())
print(len(name))

💡 Why It Matters

Used for user input, messages, and data processing.

---

📦 Tuples in Python

📖 Explanation

Tuples are similar to lists but cannot be changed (immutable).

💻 Example

numbers = (1, 2, 3)
print(numbers)

💡 Why It Matters

Used when data should not be modified.

---

🗂️ Dictionaries in Python

📖 Explanation

Dictionaries store data in key-value pairs.

💻 Example

student = {
    "name": "Rachel",
    "age": 20
}

print(student["name"])

💡 Why It Matters

Used in real-world applications like databases and APIs.

---

📥 User Input in Python

📖 Explanation

Allows users to enter data.

💻 Example

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

💡 Why It Matters

---

⚠️ Exception Handling (Error Handling)

📖 Explanation

Used to handle errors without crashing the program.

💻 Example

try:
    x = int(input("Enter a number: "))
    print(x)
except:
    print("Invalid input")

💡 Why It Matters

Improves program reliability.

---

📁 File Handling in Python

📖 Explanation

Used to read and write files.

💻 Example

file = open("test.txt", "w")
file.write("Hello World")
file.close()

---

📌 Read File

file = open("test.txt", "r")
print(file.read())
file.close()

💡 Why It Matters

Used in real applications like saving data.

---

🚀 Modules and Libraries

📖 Explanation

Python has built-in and external libraries.

import math
print(math.sqrt(16))

💡 Why It Matters

Saves time and adds powerful features.

---

🧠 Object-Oriented Programming (Basic)

📖 Explanation

Used to create structured programs using classes and objects.

💻 Example

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

p1 = Person("Rachel")
print(p1.name)
