windows compiled into exe
1. Using py2exe
Establish setup.py
from distutils.core import setup
import py2exe
setup(console=['app.py'])
carried out
python setup.py py2exe
2. Use pyinstaller
carried out
pyinstaller --distpath .dist_pyinstaller --workpath .build_pyinstaller -F app.py -n out.exe

Chinese garbled 3 recommendations
- All text string should be unicode type, rather than str, if you are in operation text, but it is the type str, that is, in the manufacturing bug.
- When you want to convert, explicit conversion. Decodes into text, with var.decode (encoding), from the text encoded into bytes, with var.encode (encoding).
- When reading data from the outside, it is the default byte, and then decode the text into the desired; the same, when it is desired to send a text to the outside, to encode byte retransmission.
