Problem Statement

Write/display a language's name in 3D ASCII.

(We can leave the definition of "3D ASCII" fuzzy, so long as the result is interesting or amusing, not a cheap hack to satisfy the task.)

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Write language name in 3D ASCII step by step in the Python programming language

Code Explanation:

1. Initializing the Python String py:

  • The code defines a string py representing a text pyramid of the word "PYTHON".
  • '#' characters in py represent pyramid blocks, ' ' (spaces) represent empty spaces, and '\n' (newlines) represent line breaks.

2. Generating Lines for the Pyramid:

  • The string py is modified using string manipulation techniques to create a list of lines for the pyramid:
    • replace is used to replace '#' with '<<<', ' ' with 'X', 'X' with ' ', and '\n' with ' Y'.
    • split is used to divide the resulting string into lines by splitting on 'Y'.

3. Printing the Lines in a Pyramid Shape:

  • A for loop iterates through the lines in reverse order (from bottom to top).
  • For each line, it prints leading spaces to align the pyramid correctly.
  • The line is then printed with the appropriate white spaces and characters.

4. Character Table for 3D Letters:

  • Four character sets are defined, each representing a different row of a 3D letter.
  • The character sets are combined into a single charTable using a list comprehension.

5. Main Function with User Input:

  • The program enters the main function when executed.
  • It prompts the user for text to convert and stores it in text. If no input is provided, it defaults to "PYTHON".

6. Generating the 3D Character Pyramid:

  • For each row in the 3D character table, the program iterates through the characters in text.
  • It determines the character's position in the alphabet and calculates the corresponding beginning and ending string positions in the character table.
  • It then extracts the portion of the character table from the beginning to the ending position and appends it to the output line.

7. Printing the 3D Character Pyramid:

  • The output line is printed for each row in the character table.
  • This creates a 3D pyramid representation of the input text.

8. Using an Online ASCII Art Generator:

  • The program makes an HTTP request to a website that generates ASCII art from text.
  • It specifies the text ("Python") and font ("larry3d") as parameters.
  • The response is parsed to extract the ASCII art, which is then printed on the screen.
