python获取一组汉字拼音首字母的方法
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/envpython
#-*-coding:utf-8-*-
defmulti_get_letter(str_input):
ifisinstance(str_input,unicode):
unicode_str=str_input
else:
try:

except:
try:
unicode_str=str_input.decode('gbk')
except:
print'unknowncoding'
return
return_list=[]
forone_unicodeinunicode_str:
return_list.append(single_get_first(one_unicode))
returnreturn_list
defsingle_get_first(unicode1):
str1=unicode1.encode('gbk')
try:
ord(str1)
returnstr1
except:
asc=ord(str1[0])*256+ord(str1[1])-65536
