python获取一组汉字拼音首字母的方法_Python

本文实例讲述了python获取一组汉字拼音首字母的方法。分享给大家供大家参考。具体实现方法如下：
									#!/usr/bin/env python 

									# -*- coding: utf-8 -*- 

									def multi_get_letter(str_input): 

									  if isinstance(str_input, unicode): 

									    unicode_str = str_input 

									  else: 

									    try: 

									      unicode_str = str_input.decode('utf8') 

									    except: 

									      try: 

									        unicode_str = str_input.decode('gbk') 

									      except: 

									        print 'unknown coding'

									        return

									  return_list = [] 

									  for one_unicode in unicode_str: 

									    return_list.append(single_get_first(one_unicode)) 

									  return return_list 

									def single_get_first(unicode1): 

									  str1 = unicode1.encode('gbk') 

									  try:     

									    ord(str1) 

									    return str1 

									  except: 

									    asc = ord(str1[0]) * 256 + ord(str1[1]) - 65536

									    if asc >= -20319 and asc <= -20284: 

									      return 'a'

									    if asc >= -20283 and asc <= -19776: 

									      return 'b'

									    if asc >= -19775 and asc <= -19219: 

									      return 'c'

									    if asc >= -19218 and asc <= -18711: 

									      return 'd'

									    if asc >= -18710 and asc <= -18527: 

									      return 'e'

									    if asc >= -18526 and asc <= -18240: 

									      return 'f'

									    if asc >= -18239 and asc <= -17923: 

									      return 'g'

									    if asc >= -17922 and asc <= -17418: 

									      return 'h'

									    if asc >= -17417 and asc <= -16475: 

									      return 'j'

									    if asc >= -16474 and asc <= -16213: 

									      return 'k'

									    if asc >= -16212 and asc <= -15641: 

									      return 'l'

									    if asc >= -15640 and asc <= -15166: 

									      return 'm'

									    if asc >= -15165 and asc <= -14923: 

									      return 'n'

									    if asc >= -14922 and asc <= -14915: 

									      return 'o'

									    if asc >= -14914 and asc <= -14631: 

									      return 'p'

									    if asc >= -14630 and asc <= -14150: 

									      return 'q'

									    if asc >= -14149 and asc <= -14091: 

									      return 'r'

									    if asc >= -14090 and asc <= -13119: 

									      return 's'

									    if asc >= -13118 and asc <= -12839: 

									      return 't'

									    if asc >= -12838 and asc <= -12557: 

									      return 'w'

									    if asc >= -12556 and asc <= -11848: 

									      return 'x'

									    if asc >= -11847 and asc <= -11056: 

									      return 'y'

									    if asc >= -11055 and asc <= -10247: 

									      return 'z'

									    return '' 

									def main(str_input): 

									  a = multi_get_letter(str_input) 

									  b = '' 

									  for i in a: 

									    b= b+i 

									  print b 

									if __name__ == "__main__": 

									  str_input=u'欢迎你'

									  main(str_input)
