函数ord()将获得int值 的字符.如果你想 玩完后转换回来 数字，函数chr(​​)可以解决问题.

function ord() would get the int value of the char. And in case you want to convert back after playing with the number, function chr() does the trick.

>>> ord('a')
97
>>> chr(97)
'a'
>>> chr(ord('a') + 3)
'd'
>>>

在Python 2中，还有一个unichr函数，返回 Unicode 字符，序数是unichr参数:

In Python 2, there is also the unichr function, returning the Unicode character whose ordinal is the unichr argument:

>>> unichr(97)
u'a'
>>> unichr(1234)
u'\u04d2'

在Python 3中，您可以使用chr代替unichr.

In Python 3 you can use chr instead of unichr.
