字典的用处非常大，昨天在网上找了个能在linux跑的字典程序，分享一下。
#!/usr/bin/python
f=open(‘wordlist’, ‘w’)
 
def xselections(items, n):
    if n==0: yield []
    else:
        for i in xrange(len(items)):
            for ss in xselections(items, n-1):
                yield [items[i]]+ss
 
# Numbers = 48 – 57
# Capital = 65 – 90
# Lower = 97 – 122
numb = range(48,58)

low = range(97,123)
choice = 0
while int(choice) not in range(1,8):
    choice = raw_input(”’
    1) Numbers
    2) Capital Letters
    3) Lowercase Letters
    4) Numbers + Capital Letters
    5) Numbers + Lowercase Letters
    6) Numbers + Capital Letters + Lowercase Letters
    7) Capital Letters + Lowercase Letters
    : ”’)
