🔍 Code Extractor

Retrieves a document status code from a dictionary lookup using the provided full name, returning the name itself if not found.

Purpose

This function serves as a lookup utility to convert human-readable document status names into their corresponding status codes. It uses a predefined DOCUMENT_STATUSES dictionary to perform the mapping. If the provided name doesn't exist in the dictionary, it returns the input name unchanged, providing a safe fallback behavior. This is commonly used in document management systems to normalize status representations.

Source Code

def get_document_status_code(name):
    """Get document status code from full name."""
    return DOCUMENT_STATUSES.get(name, name)

Parameters

Parameter Details

name: The full name of the document status to look up. Expected to be a string representing a document status (e.g., 'Draft', 'Published', 'Archived'). Can be any value; if not found in DOCUMENT_STATUSES dictionary, the function returns this value unchanged.

Return Value

Returns the status code corresponding to the provided name from the DOCUMENT_STATUSES dictionary. If the name is not found in the dictionary, returns the input 'name' parameter unchanged. The return type is typically a string or the same type as values stored in DOCUMENT_STATUSES dictionary.

Usage Example

# Assuming DOCUMENT_STATUSES is defined as:
# DOCUMENT_STATUSES = {'Draft': 'DRF', 'Published': 'PUB', 'Archived': 'ARC'}

status_code = get_document_status_code('Draft')
print(status_code)  # Output: 'DRF'

# If status name not found, returns the input
unknown_status = get_document_status_code('Unknown')
print(unknown_status)  # Output: 'Unknown'

Best Practices

• Ensure DOCUMENT_STATUSES dictionary is properly defined and accessible in the module scope before calling this function
• The function provides safe fallback behavior by returning the input if not found, preventing KeyError exceptions
• Consider validating the input 'name' parameter type if strict type checking is required
• Document the expected structure and contents of DOCUMENT_STATUSES dictionary for maintainability
• This function is stateless and thread-safe as long as DOCUMENT_STATUSES is not modified during execution
