CleverObjectArray

Overview

The CleverObjectArray class provides an object array that can be indexed and manipulated just like a typical array. This class allows for the addition, deletion, and searching of entries, ensuring efficient handling of data in object format while maintaining index-based sorting when necessary.

Class Definition

class CleverObjectArray:
    def __init__(self):
        self.data = []
        self.index_map = {}

    def add(self, name=None, value=None):
        index = len(self.data) + 1
        entry = {"index": index, "date": 'dd/mm/yy', "name": name, "value": value}
        self.data.append(entry)
        if name:
            self.index_map[name] = index
        return entry

    def delete(self, name=None, index=None):
        if name:
            index = self.index_map.get(name, None)
            if index is None:
                return f"Error: '{name}' not found."
        if index is None or index > len(self.data):
            return f"Error: Invalid index '{index}'."
        self.data.pop(index - 1)
        return f"Deleted entry with index '{index}'."

    def find_by_index(self, index):
        if index <= len(self.data):
            return self.data[index - 1]
        return f"Error: Invalid index '{index}'."

    def __repr__(self):
        return str(self.data)

Methods

__init__

• Initializes the CleverObjectArray class.
• self.data: A list to store the object entries.
• self.index_map: A dictionary to map names to their respective indexes.

add

• Adds an entry to the object array.
• Parameters:
  • name (optional): The name of the entry.
  • value (optional): The value of the entry.
• Returns the added entry.

delete

• Deletes an entry from the object array by name or index.
• Parameters:
  • name (optional): The name of the entry to delete.
  • index (optional): The index of the entry to delete.
• Returns a message indicating the result of the deletion.

find_by_index

• Finds an entry by its index.
• Parameters:
  • index: The index of the entry to find.
• Returns the entry if found, or an error message if the index is invalid.

__repr__

• Returns a string representation of the object array.

Usage Examples

Adding Entries

obj_arr = CleverObjectArray()
print(obj_arr.add("one", "everything"))  # Add entry with name and value
print(obj_arr.add("two", "nothing"))     # Add another entry

Deleting Entries

print(obj_arr.delete(name="one"))  # Delete entry by name
print(obj_arr.delete(index=2))     # Delete entry by index

Finding Entries

print(obj_arr.find_by_index(1))    # Find entry by index

Displaying All Entries

print(obj_arr)  # Display all entries in the object array

Additional Handling

Updating Entries

You can extend the class to update entries by name or index.

def update(self, name=None, index=None, value=None):
    if name:
        index = self.index_map.get(name, None)
        if index is None:
            return f"Error: '{name}' not found."
    if index is None or index > len(self.data):
        return f"Error: Invalid index '{index}'."
    self.data[index - 1]['value'] = value
    return self.data[index - 1]

Usage:

print(obj_arr.update(name="two", value="something"))  # Update entry by name
print(obj_arr.update(index=1, value="anything"))      # Update entry by index

Searching by Name

You can add a method to search entries by name.

def find_by_name(self, name):
    index = self.index_map.get(name, None)
    if index is None:
        return f"Error: '{name}' not found."
    return self.data[index - 1]

Usage:

print(obj_arr.find_by_name("two"))  # Find entry by name
