python如何将汉字转换成数字，对汉字进行编码
使用了ord函数，但是报错

Answer 1

Chinese characters cannot be represented by ascii codes, because the ord function can only convert characters into ascii codes! If you need to compare, you can use unicode codes to compare Chinese characters;

Answer 2

This problem disappears after changing to python3~

Answer 3

python2

s=u'山'
ord(s)

python3

s='山'
ord(s)
