The video tutorial guides viewers through creating a function called 'truncate' that shortens a string to a specified length, adding ellipses if the string exceeds this length. The instructor explains the logic behind the function, including conditional checks and string slicing, and demonstrates testing the function with different inputs. Viewers are encouraged to share their solutions and engage with the community.
