[root@linux-node1 src]# nova list ERROR (UnicodeEncodeError): 'ascii' codec can't encode character u'\uff08' in position 9: ordinal not in range(128) python在安装时,默认的编码是ascii,当程序中出现非ascii编码时,python的处理常常会报这样的错,python没办法处理非ascii编码的,此时需要自己设置将pyt...
Using the Python ord() function gives you the base-10 code point for a single str character. The right hand side of the colon is the format specifier. 08 means width 8, 0 padded, and the b functions as a sign to output the resulting number in base 2 (binary). This trick is ...
