@staticmethod
def reverse_binary_string_list() -> list[str]:

Description

• Returns a list with 64 items, where each item is a 6‑bit binary string reversed from right to left.

Details

• Output type: list[str]
• Total items: 64
• String length: always 6 characters
• Characters used: '0' and '1'
• Order: sequential binary representation of numbers 0–63
• Transformation: each binary string is reversed
• Mapping: index → "reversed_binary_string"

0004-D - Braille Unicode

@staticmethod
def unicode_list() -> list[str]:

Description

• Returns a list with 64 Unicode strings, each representing the hexadecimal Unicode code point of a braille character.
• The values follow the standard Unicode Braille Patterns block, from U+2800 to U+283F.

Details

• Output type: list[str]
• Total items: 64
• Format: hexadecimal Unicode strings (e.g., "2800", "2801", … "283F")
• Unicode block: Braille Patterns
• Order: strictly sequential from U+2800 to U+283F
• Mapping: index → "unicode_hex_string"

0004-E - Number of Points Per Braille

@staticmethod
def dot_count() -> list[int]:

Description

• Returns a list with 64 integers, where each value represents the number of active dots (1–6) in the corresponding braille character.
• The count is computed from the binary pattern of each braille cell.

Details

• Output type: list[int]
• Total items: 64
• Value range: integers from 0 to 6
• Order: sequential braille index (0–63)
• Mapping: index → active dot count

0004-F - Braille Dot Numbering List

@staticmethod
def dot_numbering_list() -> list[list[int]]:

Description

• Returns a list with 64 items, where each item is a list containing the active dot numbers (1–6) of the corresponding braille character.
• Dot numbering follows the standard braille convention:
• 1 4
• 2 5
• 3 6

Details

• Output type: list[list[int]]
• Total items: 64
• Dots per item: variable (0 to 6)

• Mapping: index → [dot_numbers]

0004-G - Braille Dot Numbering String List

@staticmethod
def dot_numbering_string_list() -> list[str]:

Description

• Returns a list with 64 strings, where each string contains the active dot numbers of the corresponding braille character, separated by hyphens.
• This format is commonly used in educational material and documentation.

Details

@staticmethod
def get_braille_to_index(braille: str) -> int:

Description

• Returns the numeric index (0–63) of a given braille Unicode character.

@staticmethod
def get_index_to_braille(index: int) -> str:

Description

• Returns the braille Unicode character corresponding to the given index (0–63).
• The index maps directly to the Unicode Braille Patterns block, from U+2800 to U+283F.

Details

• Input type: int
• Valid range: 0 to 63
• Output type: str (a single braille Unicode character)
• Unicode block: Braille Patterns
• Mapping: index → braille_character

0003-B - Receives a List of Braille Characters and Returns a List of Indices

@staticmethod
def get_braille_list_to_index_list(braille_list: list[str]) -> list[int]:

Description

• Converts a list of braille Unicode characters into a list of their corresponding numeric indices (0–63).

Details

• Input type: list[str]
• Output type: list[int]
• Valid index range: 0 to 63
• Unicode block: Braille Patterns
• Mapping: [braille_char1, braille_char2, ...] → [index1, index2, ...]
