python-2.7

问题 I am trying to set the default python in my docker container to be python3 and have set the aliases in the dockerfile. When I open the .bashrc file, they show up. As far as I can tell, it should work but the default python version is still 2.7. if I run which python, it will still point to usr/bin/python rather than python3. Same with pip. Can anyone tell me what the problem is? Here is the command I'm using to alias: RUN \ echo 'alias python="/usr/bin/python3"' >> /root/.bashrc && \ echo

问题 I know that the encoding can be declared this way: # -*- coding: utf-8 -*- But when i try to write 'ñ' in a file, is write 'Ã' instead. I also try of this way (like is write here in the docs) import codecs f = codecs.open('output', encoding='utf-8') f.write("ñÑ") but it raise: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128) 回答1: You are using codecs.open() , producing a file object that expects unicode objects . You are, however, passing in a
