print("Hello World")

Explanation:

• print() → output dikhata hai
• "Hello World" → string (text)

✅ Example 2: Apna Naam Print Karo

print("My name is Faheem")

📌 String hamesha quotes (” “) me hoti hai

✅ Example 4: Multiple Print Statements

print("Python")
print("Programming")
print("Language")

📌 Har print() new line me output deta hai

✅ Example 5: Print Using Comma

print("My age is", 20)

WHY comma?

• Different data types ko ek sath print karne ke liye

✅ Example 6: New Line (\n) Use

print("Hello\nWorld")

📌 \n → new line ke liye hota hai

✅ Example 7: Single Quotes Use

print('Python is easy')

📌 Python me ' ' aur " " dono valid hain

✅ Example 8: Double Quotes Inside String

print("Python is called \"Easy Language\"")

📌 \ escape character hota hai

✅ Example 9: Print with sep

print("Python", "Java", "C++", sep=" | ")

output : Python | Java | C++

📌 sep separator change karta hai

✅ Example 10: Print with end

print("Hello", end=" ")
print("World")

output : Hello World

📌 end new line ko replace karta hai

📝 DAY 1 SUMMARY (Notes Style)

• print() → output ke liye
• String → " " ya ' '
• \n → new line
• sep → separator
• end → line ending control

📌 PRACTICE (Homework)

1. Apna naam aur city print karo
2. 3 favourite subjects print karo

🐍 PYTHON – DAY 2

Topic: Variables in Python

🔹 VARIABLE KYA HAI? (WHAT)

Variable ek container hota hai jisme hum data store karte hain.

🔹 VARIABLE KYON USE KARTE HAIN? (WHY)

• Data ko bar-bar use karne ke liye
• Code readable banane ke liye
• Values change (update) karne ke liye

🔹 VARIABLE KAISE BANATE HAIN? (HOW)

Python me = assignment operator se variable banta hai.

variable_name = value

📘 DAY 2 – 10 EXAMPLES (WITH EXPLANATION)

✅ Example 1: Integer Variable

age = 20
print(age)

Explanation:

• age → variable name
• 20 → integer value
• print(age) → value show karta hai

✅ Example 2: Float Variable

price = 99.50
print(price)

📌 Decimal number = float

✅ Example 3: String Variable

name = "Amit"
print(name)

📌 Text data hamesha quotes me hota hai

✅ Example 4: Boolean Variable

is_student = True
print(is_student)

📌 Boolean sirf True / False hota hai

✅ Example 5: Multiple Variables

name = "Rahul"
age = 21
city = "Delhi"

print(name)
print(age)
print(city)

📌 Alag-alag data ko alag variables me store kar sakte hain

✅ Example 6: Print with Variables

name = "Neha"
age = 22

print("Name:", name)
print("Age:", age)

📌 String + variable print karne ke liye comma use hota hai

✅ Example 7: Variable Overwrite

x = 10
print(x)

x = 20
print(x)

Explanation:

• Pehle x = 10
• Phir x = 20 → old value replace ho gayi

✅ Example 8: Variable Swapping

a = 5
b = 10

a, b = b, a

print(a)
print(b)

📌 Python me swapping extra variable ke bina ho jati hai

✅ Example 9: Type Check (type())

x = 100
y = 5.5
z = "Python"

print(type(x))
print(type(y))
print(type(z))

📌 type() batata hai variable ka data type

✅ Example 10: Simple Calculation Using Variables

a = 10
b = 3

sum = a + b
print("Sum is:", sum)

📌 Variables ka use calculation ke liye hota hai

📝 DAY 2 SUMMARY (Notes)

• Variable = data store karne ka box
• Python me data type manually likhna nahi padta
• = assignment operator hota hai
• Value overwrite ho sakti hai
• type() se data type check hota hai

🧠 DAY 2 PRACTICE (Homework)

1. Apna naam, age aur college variable me store karo
2. Do numbers ka multiplication variable se karo
3. Ek boolean variable banao (True/False)

🐍 PYTHON – DAY 3

Topic: Data Types & Type Conversion

🔹 DATA TYPE KYA HAI? (WHAT)

Data type batata hai ki variable ke andar kis type ka data stored hai.

🔹 DATA TYPE KYON ZAROORI HAI? (WHY)

• Python ko samajhne ke liye ki kaunsa operation possible hai
• Errors se bachne ke liye
• Memory aur calculation sahi rakhne ke liye

🔹 PYTHON KE MAIN DATA TYPES (HOW)

• int → integer (whole number)
• float → decimal number
• str → string (text)
• bool → True / False

📘 DAY 3 – 10 EXAMPLES (WITH EXPLANATION)

✅ Example 1: Integer (int)

x = 50
print(x)
print(type(x))

📌 int → whole number (no decimal)

✅ Example 2: Float (float)

price = 99.99
print(price)
print(type(price))

📌 Decimal value = float

✅ Example 3: String (str)

language = "Python"
print(language)
print(type(language))

📌 Text data hamesha quotes me hota hai

✅ Example 4: Boolean (bool)

is_active = True
print(is_active)
print(type(is_active))

📌 Boolean sirf True / False

✅ Example 5: String + String

first_name = "Amit"
last_name = "Sharma"

print(first_name + last_name)

📌 Strings add hone par join (concatenate) ho jati hain

✅ Example 6: Integer + Integer

a = 10
b = 20

print(a + b)

📌 Numbers add hone par math addition hota hai

✅ Example 7: Integer + Float

x = 10
y = 2.5

print(x + y)

📌 Result hamesha float hota hai

✅ Example 8: Type Conversion (int → float)

a = 5
b = float(a)

print(b)
print(type(b))

📌 float() → int ko float me convert karta hai

✅ Example 9: Type Conversion (string → int)

num = "100"
num2 = int(num)

print(num2)
print(type(num2))

📌 String ke andar number hona chahiye, warna error aayega

✅ Example 10: Wrong Type Example

a = "10"
b = 5

print(a + str(b))

Explanation:

• a string hai
• b int hai
• Pehle b ko str() me convert kiya

📌 Same data type hona zaroori hai

📝 DAY 3 SUMMARY (Notes)

• Data type batata hai data ka nature
• Python automatically data type assign karta hai
• type() se data type check hota hai
• Type conversion → int(), float(), str()
• Mixed data type me conversion zaroori hota hai

🧠 DAY 3 PRACTICE (Homework)

1. Ek int ko float me convert karo
2. User se number input leke uska square nikalo
3. String aur number ko sahi tarike se add karo

🐍 PYTHON – DAY 4

Topic: User Input (input() Function)

🔹 INPUT KYA HAI? (WHAT)

Input ka matlab hota hai user se data lena.

🔹 INPUT KYON ZAROORI HAI? (WHY)

• Program ko dynamic banane ke liye
• Har baar alag value ke saath program chalane ke liye

🔹 INPUT KAISE LETE HAIN? (HOW)

Python me input() function ka use hota hai.

variable = input("Message")

📌 Important Note:
input() hamesha string data return karta hai.

📘 DAY 4 – 10 EXAMPLES (WITH EXPLANATION)

✅ Example 1: Name Input

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

📌 User jo likhega, wo name variable me store ho jayega

✅ Example 2: Age Input (String)

age = input("Enter your age: ")
print("Your age is", age)

📌 Yahan age string hai

✅ Example 3: Age Input (Integer)

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

📌 int() use karke string → integer banaya

✅ Example 4: Two Numbers Input

a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

print("Sum is:", a + b)

📌 Calculation ke liye type conversion zaroori hai

✅ Example 5: Float Input

price = float(input("Enter product price: "))
print("Price:", price)

📌 Decimal value ke liye float()

✅ Example 6: Full Sentence Input

msg = input("Enter a message: ")
print(msg)

📌 Space ke saath bhi input accept hota hai

✅ Example 7: Multiple Inputs (One Line)

name, city = input("Enter name and city: ").split()

print(name)
print(city)

📌 split() space ke base par data todta hai

✅ Example 8: Calculate Square

num = int(input("Enter number: "))
print("Square:", num * num)

📌 User input se calculation

✅ Example 9: String + Number (Correct Way)

age = int(input("Enter age: "))
print("Next year age:", age + 1)

📌 Pehle int conversion, phir addition

✅ Example 10: Input Error Example

num = input("Enter number: ")
print(num + "10")

Explanation:

• num string hai
• "10" bhi string hai
• Isliye result string join hoga

📌 Math ke liye conversion zaroori hai

📝 DAY 4 SUMMARY (Notes)

• input() user se data leta hai
• Input hamesha string hota hai
• Math ke liye int() / float() use karo
• split() multiple inputs ke liye useful
• Galat conversion se error aa sakta hai

🧠 DAY 4 PRACTICE (Homework)

1. User se 3 numbers input leke average nikalo
2. User se naam aur age input leke print karo
3. User se length input leke square nikalo
