This is the notes and cbse 10board result of the day bore ho Raha hu ki baba vagera koch bhi nahi hai to wo bhi

basic use of python programming

1. Variables and Data Types

Variables are containers used to keep data values.

name = "Alex"
age = 17

In Python, you dont need to define the data type manually.

2. Input and Output

These are used to receive input from users and display results.

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

---

3. Conditional Statements

Used to control decisions in a program.

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

---

4. Loops

Loops allow code to run repeatedly.

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

---

5. Functions

Functions are blocks of code that can be reused.

def greet(name):
    return "Hello " + name

---

6. Lists

Lists store multiple items in one variable.

numbers = [1, 2, 3]

---

7. Dictionaries

Used to store data with key-value pairs.

student = {"name": "Alex", "age": 17}

---

8. Error Handling

Prevents the program from crashing when errors occur.

try:
    x = int(input())
except:
    print("Error")

---

9. Comments

Comments help explain the code.
