“EBCDIC single-byte encoding scheme An 8-bit-per-byte structure. The EBCDIC single-byte structure has a valid code-point range for 00 to FF Control characters have a range from 00 to 3F. Graphic characters have a range from 41 to FE. The space character is 40.”

Printable range. This is obtained by using cp500:

string.printable.encode('cp500')

Which gives:

class TotalDepth.util.EBCDIC.EbcdicAsciiTableEntry¶

A single entry in the EBCDIC table.

decimal_str¶: Alias for field number 0

hex_str¶: Alias for field number 1

ctrl_char¶: Alias for field number 2

ascii¶: Alias for field number 3

ascii_meaning¶: Alias for field number 4

ebcdic¶: Alias for field number 5

ebcdic_meaning¶: Alias for field number 6

value¶: Returns the decimal value of the entry.

is_ctrl¶: Returns True if this is a control character, False otherwise.

ctrl_symbol¶: The single control character or ‘’. For example decimal value 3 returns ‘C’.

ebcdic_printable¶: Returns True if this is a printable character, False otherwise.

__getnewargs__()¶: Return self as a plain tuple. Used by copy and pickle.

static __new__(_cls, decimal_str: str, hex_str: str, ctrl_char: str, ascii: str, ascii_meaning: str, ebcdic: str, ebcdic_meaning: str)¶: Create new instance of EbcdicAsciiTableEntry(decimal_str, hex_str, ctrl_char, ascii, ascii_meaning, ebcdic, ebcdic_meaning)

__repr__()¶: Return a nicely formatted representation string

TotalDepth.util.EBCDIC.ebcdic_all_printable(byt: bytes) → bool¶: True if all character codes are printable EBCDIC.

TotalDepth.util.EBCDIC.ebcdic_ascii_description(byt: bytes) → TotalDepth.util.EBCDIC.EbcdicAsciiTableEntry¶: Look up the first character in the given bytes and return the EBCDIC table entry.

TotalDepth.util.EBCDIC.ebcdic_to_ascii(byt: bytes) → str¶: Convert EBCDIC to ASCII.

TotalDepth.util.EBCDIC.ascii_to_ebcdic(ascii_str: str) → bytes¶: Convert ASCII to EBCDIC.
