How to set equal width of ASCII-characters in Code-Playground's Python-Output?

Question

In my code
https://code.sololearn.com/ch8o7903hzHT/?ref=app I have gathered all characters which can be obtained with the chr()-function in Python. As one can see, the width of the characters with numbers of 176 and above differ from the lower ones.

Is there a chance to set it to equal width for all of the printable characters, and how would I have to achieve this?

Answer 1

A note: Codes output to pipe (not a rendering device):

* So LunarCoffee's right; SoloLearn would have to change the app (perhaps not as simple as it appears). Instead...
* Python's detecting/set to ASCII (<128) when utf_16 works:

With the 2 lines for utf_16 you get more options like various Unicode spaces:

This may be the way, because we're missing variable-width-handling imports:
ftfy: https://github.com/LuminosoInsight/python-ftfy/blob/master/ftfy/formatting.py
wcwidth: https://pypi.org/project/wcwidth/

Answer 2

I'm pretty sure the widths of those characters are defined by the font. Either way, I'm pretty sure there isn't a way to fix this.

@ Kirk Schafer

Thank you very much for your information! It is amazing what characters can be displayed in code playground. But that's a little of hard stuff for me at the moment - perhaps tomorrow.

Answer 4

You just need these two lines at the top of your program:

import sys, codecs
sys.stdout = codecs.getwriter('utf_16')(sys.stdout.buffer, 'strict')

Then you can print any unicode character you want (in SoloLearn), including just pasting them in from a website.

At home/work for just aligning those ASCII (0-255) characters, you can try changing the font:

thank you, that's nice to read!
I will try this as soon as possible. :-)

Answer 6

@ Tim

Yes, that would be the best solution, I think. ;-)

Answer 7

@ tamaslud

I discovered the same today. When I opened code playground on my computer (at work on MS Internet Explorer), all characters have an identical width.
But on my Android phone that's not the case as I mentioned in my initial posting.

Answer 8

Programm your own Python Interpreter in an Web document, set the font of the output textfield to mono-space and run it in SL ;)

Answer 9

i am strugling with the same thing.
the char output is proper in PC environment, but not on my android phone. i received some notifications earlier, that on some phones the situation is not so critical, there are 2 incoherent chars altogether, which is bearable.
i don't know whether it is phone specific, SL version specific, or OS specific.
