ord() and chr() Function in Python.

In Python, the ord() and chr() functions are essential tools for working with Unicode, they allow you to convert an integer to Unicode and Unicode to an integer respectively. Let's dive deeper into these functions.

What is Unicode?

Unicode is a standardized character encoding system that assigns a unique number, known as a code point, to every character in almost every script and language in the world. It is designed to be a universal character set, encompassing characters from different writing systems. For example, 'A' is assigned the code point 65, and '❤' is assigned the code point 2764.

What is ord() in Python?

The ord() function in Python is a built-in function that returns an integer representing the Unicode character. It stands for "ordinal," and its primary use is to obtain the Unicode code point of a given character.

Syntax:

ord(character)

Python Code:

# Using ord() to get the Unicode code point of a character

unicode_value = ord('A')

print(f"The Unicode code point of 'A' is {unicode_value}")

Output:

The Unicode code point of 'A' is 65

In this example, ord('A') returns 65, which is the Unicode code point for the character 'A'.

What is chr() in Python?

In Python, chr() is a built-in function that converts an integer representing a Unicode code point into the corresponding character. The name chr stands for "character." This function is the inverse of the ord() function, which converts a character to its Unicode code point.

Syntax: 

# i is an integer representing an integer point
chr(i)

Python Code:

# Using chr() to convert a Unicode code point to a character
unicode_code_point = 65  # Unicode code point for 'A'
character = chr(unicode_code_point)

# Printing the result
print(f"The character to the Unicode code point {unicode_code_point} is: {character}")

In this example, chr(65) returns the character 'A' because 65 is the Unicode code point for the uppercase letter 'A.'

In this article, we have discussed ord() and chr() functions which help us in working with Unicode. It is an important concept to learn for solving many real-life coding problems.

Python Program To Find ASCII Value of a character.

Finding the ASCII value of a character in Python programming is useful for solving many coding problems. In this tutorial, we will learn different ways to find the ASCII  value of any given character.

What is ASCII Value?

ASCII, which stands for American Standard Code for Information Interchange, is a character encoding standard used for representing text and control characters in computers and other devices that use text.

In ASCII, each character is assigned a unique numeric value. The standard ASCII set uses values ranging from 0 to 127, representing basic characters such as letters, digits, punctuation, and control characters.

Example:

• The ASCII value for the uppercase letter 'A' is 65.
• The ASCII value for the lowercase letter 'a' is 97.
• The ASCII value for the digit '0' is 48.
• The ASCII value for the exclamation mark '!' is 33.

Python Code to Find ASCII Value of a Character.

In Python, the ord() function can be used to find the ASCII value of a character.

Here's a simple Python program to get ASCII value:

character = input("Enter a character: ")

# ASCII value of character
ascii_value = ord(char)

print(f"The ASCII value of {character} is {ascii_value}")

Output:

Enter a character: D
The ASCII value of D is 68

The ord() function in Python is a built-in function that returns an integer representing the Unicode character. 

Python Program to Find Character from ASCII Value.

The chr() function is the inverse of ord(). It converts an ASCII value to its corresponding character. 

Here is a simple Python Code to get a Character from an ASCII value:

ascii_value = int(input("Enter an ASCII value: "))

character = chr(ascii_value)

print(f"The character for ASCII value {ascii_value} is {character}")

Output:

Enter an ASCII value: 65
The character for ASCII value 65 is A

These approaches showcase the simplicity and flexibility of Python when working with ASCII values.

Hash Table Chaining in C++.

One of the key challenges in hash table implementation is handling collisions, where two keys hash to the same index. Chaining and Open Addressing are two techniques that help us to manage these collisions gracefully. In this tutorial, you will learn how to handle collisions using the Chaining method in detail. 

What is Hash Table Chaining?

In chaining collision, each bucket or index of the hash table contains a linked list or another data structure. When a collision occurs, the colliding elements are appended to the linked list at the corresponding index. Chaining allows multiple elements with the same hash value to coexist at the same index.

Advantages of Chaining in Hash Table.

• Chaining handles collisions effectively, ensuring that no data is lost.

• Chaining facilitates dynamic resizing, accommodating varying numbers of elements.

• Implementing chaining is straightforward, making it an attractive option for hash table design.

Disadvantages of Chaining in Hash Table.

• Each element requires additional memory for the linked list pointers, contributing to increased memory overhead.

• In scenarios with high collision rates, the performance of the linked lists might degrade, impacting overall hash table performance.

Implementation of Chaining.

Instead of storing multiple elements at the same index, chaining involves maintaining a linked list (or another data structure) at each index to store all colliding elements.

Hash Function: The hash function calculates the hash value for each key. The hash value determines the index at which the key's corresponding value will be stored.

Index Calculation: Calculate the hash value using the hash function: index = hash(key) % table_size.

Collision Occurs: If two keys hash to the same index, a collision occurs. In chaining, this is not a problem.

Linked List Handling: Each index in the hash table contains a linked list. If the linked list is empty, insert the key-value pair at the corresponding index and if the linked list is not empty, append the key-value pair to the end of the list.

Searching: When searching for a key, calculate its hash and navigate the linked list at the corresponding index. If the key is found in the linked list, return its associated value and if the linked list is empty or the key is not found, the key is not in the hash table.

Deleting: To delete a key, calculate its hash and search for it in the linked list. If found, remove the node from the linked list. If the linked list becomes empty after deletion, update the index in the hash table.

C++ code to implement Chaining in Hash Table:

// C++ code of chaining in hash table
#include <iostream>
#include <list>
using namespace std;

// HashTable class with Chaining
class HashTable {
private:
    int table_size;  // Size of the hash table
    // Array of linked lists
    list<pair<int, int>>* table;  

    // Hash function to determine the index
    int hash(int key) {
        return key % table_size;
    }

public:
    // Constructor to initialize the hash table
    HashTable(int size) {
        table_size = size;
        table = new list<pair<int, int>>[table_size];
    }

    // Function to insert a key-value pair into the hash table
    void insert(int key, int value) {
        int index = hash(key);
        table[index].push_back(make_pair(key, value));
    }

    // Function to search for a key and return its value
    int search(int key) {
        int index = hash(key);
        for (auto& it : table[index]) {
            if (it.first == key) {
                return it.second;  // Key found, return its value
            }
        }
        return -1;  // Key not found
    }

    // Function to delete a key from the hash table
    void remove(int key) {
        int index = hash(key);
        for (auto it = table[index].begin(); it != table[index].end(); ++it) {
            if (it->first == key) {
                table[index].erase(it);  // Remove the key-value pair
                break;
            }
        }
    }

    // Function to display the hash table
    void display() {
        for (int i = 0; i < table_size; ++i) {
            cout << "[" << i << "] -> ";
            for (const auto& it : table[i]) {
                cout << "(" << it.first << ", " << it.second << ") -> ";
            }
            cout << "nullptr\n";
        }
    }
};

// Main function for testing
int main() {
    // Create a hash table with a size of 5
    HashTable hashTable(5);

    // Insert key-value pairs
    hashTable.insert(25, 250);
    hashTable.insert(14, 140);
    hashTable.insert(7, 70);

    // Display the hash table
    cout << "Hash Table after Insertion:\n";
    hashTable.display();

    // Search for a key
    int searchResult = hashTable.search(14);
    if (searchResult != -1) {
        cout << "Value for key 14: " << searchResult << "\n";
    } else {
        cout << "Key 14 not found.\n";
    }

    // Remove a key
    hashTable.remove(14);
    cout << "\nHash Table after Removal:\n";
    hashTable.display();

    return 0;
}

Output:

Hash Table after Insertion:
[0] -> (25, 250) -> nullptr
[1] -> nullptr
[2] -> (7, 70) -> nullptr
[3] -> nullptr
[4] -> (14, 140) -> nullptr
Value for key 14: 140

Hash Table after Removal:
[0] -> (25, 250) -> nullptr
[1] -> nullptr
[2] -> (7, 70) -> nullptr
[3] -> nullptr
[4] -> nullptr

This C++ code defines a HashTable class with chaining. It includes functions for inserting, searching, removing keys, and displaying the hash table. The main function demonstrates the usage of the hash table with a few key-value pairs.

        else:
            print("Invalid month. Month should be between 1 and 12.")
    except ValueError:
        print("Please enter valid numeric values for year and month.")

# Call the function to print the calendar
print_month_calendar()

Output:

Enter the year (e.g., 2023): 2024
Enter the month (1-12): 2
