Question

这是程序。它在IDLE上工作得很好但是在询问你是否知道密码长度后崩溃了。我似乎无法弄清楚我是否想要失踪。我很乐意帮忙。

import itertools
import string
import sys, os, cmd

from datetime import datetime
FMT = '%Y-%m-%d %H:%M:%S'
passwordstried = 0


numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0,]
#symbols = [
lowercaseletters =  ["q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","g","h","j","k","l","z","x","c","v","b","n","m"]
uppercaseletters = ["Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","G","H","J","K","L","Z","X","C","V","B","N","M"]


stuff = lowercaseletters + uppercaseletters + numbers

if (input("Do you have the length of the password?") == 'y'):
    lengthstartingvalue = int(input("Password length: "))
else:
    lengthstartingvalue = 0


starttime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
print(starttime)





starttime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
for L in range(lengthstartingvalue, len(stuff)+1):
    for subset in itertools.combinations_with_replacement(stuff, L):
        print(subset)
        passwordstried = passwordstried + 1
    if (L>lengthstartingvalue-1):
        break

endtime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
elapsed = datetime.strptime(endtime, FMT) - datetime.strptime(starttime, FMT)
print ('Time elapsed:',elapsed)
print ('Passwords tried:',passwordstried)

@ 275365是对的，你应该使用

if (raw_input("Do you have the length of the password?") == 'y'):

而不是

if (input("Do you have the length of the password?") == 'y'):

使用input()会导致崩溃，

In [11]: run tt.py
Do you have the length of the password?y
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
C:\Program Files (x86)\ipython-0.12.1\IPython\utils\py3compat.py in execfile(fname, glob, loc)
    166             else:
    167                 filename = fname
--> 168             exec compile(scripttext, filename, 'exec') in glob, loc
    169     else:
    170         def execfile(fname, *where):

D:\Users\sp\Desktop\tt.py in <module>()
     16 stuff = lowercaseletters + uppercaseletters + numbers
     17
---> 18 if (input("Do you have the length of the password?") == 'y'):
     19     lengthstartingvalue = int(input("Password length: "))
     20 else:

D:\Users\sp\Desktop\<string> in <module>()

NameError: name 'y' is not defined

将其更改为raw_input()时会运行完成而不会崩溃。

Answer 2

似乎你可能正在运行一个不同于IDLE的IDLE版本。如果我理解正确，raw_input（）可以在你的CMD上运行但是在IDLE中断，而input（）在IDLE中工作并在CMD中断。您可能需要为Python 3下载适当版本的IDLE，或者如果您拥有它，则只需访问Python 2的版本。

否则，Windows中的Path变量可能会出现问题。在系统 - ＆gt;高级系统设置 - ＆gt;环境变量 - ＆gt;路径 - 需要设置为Python 3.3安装。

对我来说，似乎你的Path可能仍然停留在以前的安装上。
