Learn Python in One Video in Nepali: A Beginner’s Guide

Python is one of the most popular programming languages today. It's beginner-friendly, versatile, and widely used in various fields, from web development to data science. If you are just starting out with Python and want to learn the basics, this guide is for you. Let’s explore the fundamentals of Python programming, one step at a time, all in one video tutorial, explained in Nepali!

---

1. Print Statement (प्रिन्ट स्टेटमेन्ट)

In Python, the print statement is used to display output on the screen. This is one of the first things you’ll learn.

python
print("नमस्ते, Python!")

Output:

नमस्ते, Python!

The print() function helps you show any message, numbers, or even the result of calculations.

---

2. Input Statement (इनपुट स्टेटमेन्ट)

The input statement is used to take input from the user. You can prompt users to type something and store that value in a variable.

python
name = input("तपाईको नाम के हो? ")
print("नमस्ते, " + name)

This will ask the user for their name and greet them.

---

3. Variables (भेरिएबल्स)

Variables are like containers that hold data. You can store different types of values such as numbers, strings, or lists in them.

python
age = 25
name = "Ram"
height = 5.8

In Python, you don’t need to specify the data type explicitly. Python will figure it out.

---

4. Operators (अपरेटरहरू)

Operators in Python allow you to perform operations on variables and values. There are different types of operators:

• Arithmetic Operators: +, -, *, /

  python
  result = 5 + 3  # Adds two numbers
  print(result)
  

• Comparison Operators: ==, !=, >, <

  python
  print(5 > 3)  # True
  

• Logical Operators: and, or, not

  python
  print(5 > 3 and 2 < 3)  # True
  

---

5. Lists (लिस्ट)

Lists are used to store multiple items in a single variable. A list can contain different data types.

python
fruits = ["apple", "banana", "mango"]
print(fruits[0])  # Accessing the first item

You can add, remove, and modify items in a list.

---

6. Dictionary (डिक्सनरी)

A dictionary in Python is a collection of key-value pairs. It’s great for storing related data together.

python
student = {"name": "Sita", "age": 21, "grade": "A"}
print(student["name"])  # Accessing value using a key

This allows you to map one set of values to another.

---

7. Tuples (टपल्स)

Tuples are similar to lists, but they are immutable, meaning you cannot change them after they are created.

python
colors = ("red", "green", "blue")
print(colors[1])  # Accessing the second item

Tuples are useful for fixed data that shouldn’t be altered.

---

8. Sets (सेट)

A set is an unordered collection of unique items. Sets are great for storing data without duplicates.

python
numbers = {1, 2, 3, 3, 4}
print(numbers)  # Output will be {1, 2, 3, 4}

Sets are also useful for set operations like union, intersection, etc.

---

9. Conditionals (कन्डिसनल्स)

Conditional statements allow you to execute code based on certain conditions. In Python, you can use if, elif, and else.

python
age = 18
if age >= 18:
    print("वयस्क")
else:
    print("नाबालिग")

This checks the condition and prints accordingly.

---

10. Loops (लूप्स)

Loops help in running the same code multiple times. Python supports for and while loops.

• For Loop: Used to iterate over a sequence.

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

• While Loop: Keeps running until a condition is true.

  python
  count = 0
  while count < 5:
      print(count)
      count += 1
  

---

11. Try Except (त्राई-एक्सेप्ट)

The try and except blocks are used to handle errors in Python. This prevents the program from crashing.

python
try:
    x = int(input("कुनै संख्या टाइप गर्नुहोस्: "))
    print(x)
except ValueError:
    print("संख्या टाइप गर्नुहोस्!")

This handles the case where the user enters something other than a number.

---

12. File Handling (फाइल ह्यान्डलिङ)

Python allows you to open, read, write, and close files using built-in functions.

python
file = open("data.txt", "w")  # Open a file in write mode
file.write("This is a sample text.")
file.close()

You can also read data from files:

python
file = open("data.txt", "r")
content = file.read()
print(content)
file.close()
