python 3.0, how to make print() output unicode?

unicode console printing python-3.x stdout

Solution 1

The Windows command prompt (cmd.exe) cannot display the Unicode characters you are using, even though Python is handling it in a correct manner internally. You need to use IDLE, Cygwin, or another program that can display Unicode correctly.

See this thread for a full explanation: http://www.nabble.com/unable-to-print-Unicode-characters-in-Python-3-td21670662.html

Solution 2

You may want to try changing the environment variable "PYTHONIOENCODING" to "utf_8." I have written a page on my ordeal with this problem.

Solution 3

Check out the question and answer here, I think they have some valuable clues. Specifically, note the setdefaultencoding in the sys module, but also the fact that you probably shouldn't use it.

Solution 4

The problem of displaying Unicode charaters in Python in Windows is known. There is no official solution yet. The right thing to do is to use winapi function WriteConsoleW. It is nontrivial to build a working solution as there are other related issues. However, I have developed a package which tries to fix Python regarding this issue. See https://github.com/Drekin/win-unicode-console. You can also read there a deeper explanation of the problem. The package is also on pypi (https://pypi.python.org/pypi/win_unicode_console) and can be installed using pip.

Solution 5

Here's a dirty hack:

# works
import os
os.system("chcp 65001 &")
print("юникод")

However everything breaks it:

simple muting first line already breaks it:

# doesn't work
import os
os.system("chcp 65001 >nul &")
print("юникод")

checking for OS type breaks it:

# doesn't work
import os
if os.name == "nt":
    os.system("chcp 65001 &")

print("юникод")

it doesn't even works under if block:

# doesn't work
import os
if os.name == "nt":
    os.system("chcp 65001 &")
    print("юникод")

But one can print with cmd's echo:

# works
import os
os.system("chcp 65001 & echo {0}".format("юникод"))

and here's a simple way to make this cross-platform:

# works

import os

def simple_cross_platrofm_print(obj):
    if os.name == "nt":
        os.system("chcp 65001 >nul & echo {0}".format(obj))
    else:
        print(obj)

simple_cross_platrofm_print("юникод")

but the window's echo trailing empty line can't be suppressed.

thanks for your answer but that is not what i want to know... have u seen the image i have attached? i have a table and i want drop down i the first coulmn.
Sean about 6 years

Yes I looked at your image. Do you want <td contenteditable="true" class="item_name"></td> to be a dropdown? Or do you just want to put a dropdown inside -> <td contenteditable="true" class="item_name"><select>....</select></td>? If the 1st, then use the link I suggested (you have to change the <p> to <td>. If the 2nd, not sure what your issue is.
