#利用python生成一个随机10位的字符串
import string
import random
import re
list = list(string.lowercase + string.uppercase) + [ str(i) for i in range(10)]
FH = ('!','@','#','$','%','&','_')
for f in FH:
    list.append(f)
num = random.sample(list,10) 
'''随机取出10个数'''
str=''
value = str.join(num) #将取出的十个随机数进行重新合并
if not value[0].isdigit():
    print value
