实现了一种模拟windows排序的python方法，其排序规则为：
- 不处理浮点数
- 特殊字符（如：&、$、# 等）排在数字和字母之前；
- 数字优先于字母排序；
- 数字是连着的整数，应该按照整数进行排序；
- 小写字母排在大写字母前面；
- 英文字符按字母表顺序排序；

for c in str_value:
c_ascii = ord(c)
if c_ascii <= 57 and c_ascii >= 48:

if digital_flag:
digital_res = int(digital_res)
rank_value.append((1, digital_res))
digital_res = ""

if c_ascii <= 47 or (c_ascii >= 58 and c_ascii <= 64) or (c_ascii >= 91 and c_ascii <= 96) or c_ascii >= 123:
