Python Programming Malayalam Tutorial

Introduction

This tutorial provides a comprehensive guide to Python programming, tailored for Malayalam speakers. It covers everything from installation to advanced concepts like object-oriented programming. By following the steps outlined below, you'll gain foundational knowledge in Python, enabling you to start your programming journey.

Step 1: Install Python and PyCharm

• Download Python from the official website: Python.org.
• Install Python by running the installer and following the prompts. Ensure you check the option to add Python to your PATH.
• Download and install PyCharm, a popular IDE for Python development, from JetBrains.
• Open PyCharm and create a new project to start coding.

Step 2: Write Your First Python Program

• Open PyCharm and create a new Python file in your project.
• Type the following code to print "Hello, World!" on the screen:

  print("Hello, World!")
  

• Run the program by clicking the run icon or using the shortcut (Shift + F10).

Step 3: Understand Data Types and Variables

• Familiarize yourself with basic data types in Python:
  • Integers: Whole numbers (e.g., 5, 100)
  • Floats: Decimal numbers (e.g., 5.5, 100.0)
  • Strings: Text (e.g., "Hello")
  • Booleans: True or False values
• Declare variables using:

  age = 25  # Integer
  name = "John"  # String
  height = 5.9  # Float
  is_student = True  # Boolean
  

Step 4: Explore Python Operators

• Learn about different types of operators:
  • Arithmetic Operators: +, -, *, /, %
  • Comparison Operators: ==, !=, >, <, >=, <=
  • Logical Operators: and, or, not
• Example usage:

  a = 10
  b = 20
  print(a + b)  # Outputs 30
  

Step 5: Work with Python Strings

• Understand string manipulation techniques:
  • Concatenation: full_name = first_name + " " + last_name
  • String methods: upper(), lower(), replace(), split()
• Example:

  greeting = "Hello"
  print(greeting.upper())  # Outputs "HELLO"
  

Step 6: Learn About Lists

• Create and manipulate lists:
  • Definition: my_list = [1, 2, 3, 4]
  • Access elements: print(my_list[0]) # Outputs 1
  • Common methods: append(), remove(), sort()

Step 7: Understand Tuples

• Define tuples, which are immutable lists:
  • Example: my_tuple = (1, 2, 3)
• Access elements similarly to lists but remember they cannot be modified.

Step 8: Explore Sets

• Create sets to store unique items:
  • Example: my_set = {1, 2, 3}
• Common operations: add(), remove(), union(), intersection()

Step 9: Use Dictionaries

• Learn how to use dictionaries for key-value pairs:
  • Example: my_dict = {"name": "John", "age": 25}
• Access values using keys: print(my_dict["name"]) # Outputs "John"

Step 10: Control Flow with If Else Statements

• Implement conditional logic:
  • Example:

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

Step 11: Utilize Loops

• Understand while and for loops for iteration:
  • While loop example:

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

  • For loop example:

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

Step 12: Define and Use Functions

• Create reusable pieces of code:
  • Function definition:

  def greet(name):
      return f"Hello, {name}!"
  

• Call the function:

  print(greet("Alice"))
  

Step 13: Understand Recursion

• Explanation of recursion as a function calling itself.
• Example:

  def factorial(n):
      if n == 0:
          return 1
      else:
          return n * factorial(n - 1)
  

Step 14: Explore Lambda Functions

• Use lambda functions for concise function definitions:
  • Example:

  square = lambda x: x * x
  print(square(5))  # Outputs 25
  

Step 15: Learn About Object Oriented Programming

• Grasp the basics of classes and objects:
  • Example:

  class Dog:
      def bark(self):
          return "Woof!"
  
  my_dog = Dog()
  print(my_dog.bark())
  

Step 16: Understand Inheritance in OOP

• Learn how inheritance allows a class to inherit attributes and methods from another class:
  • Example:

  class Animal:
      def speak(self):
          return "Animal speaks"
  
  class Cat(Animal):
      def speak(self):
          return "Meow"
  
  my_cat = Cat()
  print(my_cat.speak())  # Outputs "Meow"
  

Step 17: Utilize Math Functions

• Import and use the math module:

  import math
  print(math.sqrt(16))  # Outputs 4.0
  

Step 18: Work with Python Modules

• Organize code into modules for better structure.
• Example of importing a module:

  import my_module
  

Step 19: Handle User Inputs

• Get input from users using the input() function:

  name = input("Enter your name: ")
  print(f"Hello, {name}!")
  

Step 20: Master File Handling

• Learn to read from and write to files:
  • Writing to a file:

  with open("example.txt", "w") as file:
      file.write("Hello, World!")
  

  • Reading from a file:

  with open("example.txt", "r") as file:
      content = file.read()
      print(content)
  

Conclusion
