Python 怎么获取拼音的首字母。
下面通过对字符串的判断，如果是中文，则获取首字母；
如果是数字或者字母，则保留下来。 如果想删除，去掉相关代码即可
下面就是 python 获取拼音首字母：
# 调用方法
str_zhongwen="获取拼音首字母"
print(getFirstLetter(str_zhongwen))
输出结果: hqpyszm
# 中文获取首字母(所有文字)
def getFirstLetter(string):
if string == None:
return None
lst = list(string)
charLst = []
for l in lst:
if is_Chinese(l):
charLst.append(get_first_code(l))
elif re.match('^[a-zA-Z0-9]+$', l):# 如果是0 ，字母和正整数，则直接拿过去
charLst.append(l.lower())
return ''.join(charLst)
# python 判断是否是中文字符
def is_Chinese(string):
for ch in string:
if '\u4e00' <= ch <= '\u9fff':
return True
return False
def get_first_code(one_word):
str1 = one_word.encode('gbk')
try:
ord(str1)
return str1
except:
asc = str1[0] * 256 + 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:

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 ''
