Printing Extended ASCII characters in Python

Question

I'd like to create menu boxes in Python with the following ascii characteres:

ASCII code 200 = ╚ ( Box drawing character double line lower left corner )

ASCII code 201 = ╔ ( Box drawing character double line upper left corner )

ASCII code 202 = ╩ ( Box drawing character double line horizontal and up )

ASCII code 203 = ╦ ( Box drawing character double line horizontal down )

ASCII code 204 = ╠ ( Box drawing character double line vertical and right )

ASCII code 205 = ═ ( Box drawing character double horizontal line )

ASCII code 206 = ╬ ( Box drawing character double line horizontal vertical )

However it seems that these are not supported. When I use chr() the system prints something totally different.

Do you have any advise on how to print the mentioned characters using Python 3?

Thank you.

None of those are ascii, ascii only goes up to 127, and "extended ascii" doesn't mean anything. — Josh Lee

May depend on which OS and terminal emulator/shell/command prompt you are using (and what character sets you can get), but on Windows 7 print('\xc8') thru print('\xce') display those 7 characters for me (╚ to ╬) — chickity china chinese chicken

It seems to work with string literals:

>>> symbs = [u'\u255a', u'\u2554', u'\u2569', u'\u2566', u'\u2560', u'\u2550', u'\u256c']
>>> for sym in symbs:
...     print(sym)
... 
╚
╔
╩
╦
╠
═
╬

This appears to work on all platforms I've tried it on, Windows 7, Mac OS , Linux, etc.

Codes gotten from http://svn.python.org/projects/stackless/trunk/Lib/encodings/cp720.py

Hope this helps.

Thanks a lot. This is what I was looking for.

Actually, in general Codepage 437 is a better choice. The codepage you link to is specific for Arabic systems; 437 is the semi-official "original" extended ASCII set.

It was little troublesome to look for all unicodes in the shared link and pick required ones. So, for quick look up, here are unicodes for single& double lined box: DOUBLE_LEFT_TOP = u'\u2554' ╔ DOUBLE_VERTI_PIPE = u'\u2551' ║ DOUBLE_LEFT_BOTTOM = u'\u255a' ╚ DOUBLE_RIGHT_TOP = u'\u2557' ╗ DOUBLE_RIGHT_BOTTOM = u'\u255d' ╝ DOUBLE_HORIZ_PIPE = u'\u2550' ═ SINGLE_LEFT_TOP = u'\u250c' ┌ SINGLE_VERTI_PIPE = u'\u2502' │ SINGLE_LEFT_BOTTOM = u'\u2514' └ SINGLE_RIGHT_TOP = u'\u2510' ┐ SINGLE_RIGHT_BOTTOM = u'\u2518' ┘ SINGLE_HORIZ_PIPE = u'\u2500' ─

def draw_box (width, height, box):
    span = width-2
    line = box.horizontal * (span)
    print (box.top_left + line + box.top_right)
    body = box.vertical + (' '*span) + box.vertical
    for _ in range (height-1):
        print (body)
    print (box.low_left + line + box.low_right)

draw_box (20, 10, Borders1)
