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.

# this is a comment

---

10. Modules

Modules let you use built-in features or external libraries.

import math
