>>> from xpinyin import Pinyin
>>> p = Pinyin()
>>> # default splitter is `-`
>>> p.get_pinyin(u"上海")
'shang-hai'
>>> # show tone marks
>>> p.get_pinyin(u"上海", tone_marks='marks')
'shàng-hǎi'
>>> p.get_pinyin(u"上海", tone_marks='numbers')
>>> 'shang4-hai3'
>>> # remove splitter
>>> p.get_pinyin(u"上海", '')
'shanghai'
>>> # set splitter as whitespace
>>> p.get_pinyin(u"上海", ' ')
'shang hai'
>>> p.get_initial(u"上")
'S'
>>> p.get_initials(u"上海")
'S-H'
>>> p.get_initials(u"上海", u'')
'SH'
>>> p.get_initials(u"上海", u' ')
'S H'
如果方法中傳入變量，那么直接加前綴是不可以了。而是要將變量轉(zhuǎn)為utf-8編碼：
>>> wordvalue = '中國'
>>> wordvalue= unicode(wordvalue,'utf-8')
>>> s = p.get_initials(wordvalue, u'').lower()
'zg'
