The self keyword in Python refers to the instance of the class, allowing access to its attributes and methods.

• Used in instance methods to refer to the object itself.

• Allows access to instance variables: e.g., self.name = 'John'.

• Distinguishes between instance variables and local variables.

• Required as the first parameter in instance methods: def method(self):.

• Enables method chaining: self.method1().method2().

OOPs (Object-Oriented Programming) is a programming paradigm based on objects and classes, promoting code reusability and modularity.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class from an existing class, inheriting its properties (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present th...read more

Reversing a string involves rearranging its characters in the opposite order, which can be done using various programming techniques.

• Use built-in functions: In Python, use 'string[::-1]' to reverse a string. Example: 'hello' becomes 'olleh'.

• Iterative approach: Loop through the string from the end to the beginning and build a new string. Example: 'world' becomes 'dlrow'.

• Recursive method: Define a function that call...read more

An Armstrong number is a number that is equal to the sum of its own digits raised to the power of the number of digits.

• An example of a 3-digit Armstrong number is 153: 1^3 + 5^3 + 3^3 = 153.

• Another example is 9474: 9^4 + 4^4 + 7^4 + 4^4 = 9474.

• Armstrong numbers can be found in any number of digits, e.g., 0-9 are all Armstrong numbers.

• To check if a number is an Armstrong number, convert it to a string to count digi...read more

Code to check if a string is a palindrome or not

• Create a function that takes a string as input

• Reverse the string and compare it with the original string

• If they are the same, return true; otherwise, return false

Use a loop to iterate through each word in the string and compare their lengths to find the largest word.

• Split the string into an array of words using a space as the delimiter

• Initialize a variable to store the largest word found so far

• Iterate through the array of words and compare the length of each word to the length of the current largest word

• Update the largest word if a longer word is found

• Print the largest wor...read more
