Python3. 获取中文首字母

今天想获取中文首字母，网上一搜基本都是python2的脚本，试了几个不行，只得在原有脚本基础上改改。

python2的如下脚本在python3上运行是不能通过的

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

经过反复思考查证，最终解决了这个问题，现附上思考过程：


就是酱紫。所以下边附上python3支持的获取中文首字母的方法

def single_get_first(unicode1):
    str1 = unicode1.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:
            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:
