代碼如下:
#!/usr/bin/python  
# Filename: gen_salt.py  
import random  

salt =[]  
for i in range(0, 30):  
  salt.append( random.randint(-128, 127) )  

print salt

執行 $ python gen_salt.py 后結果形式如下

[4, 30, 42, -124, -120, -75, 77, 38, -112, 35, 4, -19, -9, -83, 122, -115, -34, 44, -95, -31, -102, -94, -85, -20, -73, 126, -16, 28, 20, -54]
