如何更改此 Python 程序的输出

Question

我写了一个简单的python密码生成器：

import string
import random

print "Password generator will create a random customizable password."
print "Choose your options wisely."

number = int(raw_input("How many letters do you want in your password?"))
caps = str(raw_input("Do you want capital letters in your password? Y/N:"))
symbols = str(raw_input( "Do you want punctuation and other symbols in your password?    Y/N:"))
otherchoice = str(raw_input( "Do you want numbers in your password? Y/N:"))

punctuation = ("!", ".", ":", ";", ",", "?", "'", "@", "$", "~", "^","%", "#", "&", "/")
numbers = map(str,range(0,10))
stringpunctuation = "".join(punctuation)
stringnumbers = "".join(numbers)
lowercase = string.ascii_lowercase
uppercase = string.ascii_uppercase

if caps == "Y":
    characters = lowercase + uppercase
else:
    characters = lowercase

if symbols == "Y":
    characters += stringpunctuation
if otherchoice == "Y":
    characters += stringnumbers

password = random.sample(characters, number)
print "The password is", password

这是我运行终端时出现的示例：

Password generator will create a random customizable password.
Choose your options wisely.
How many letters do you want in your password?15
Do you want capital letters in your password? Y/N:Y
Do you want punctuation and other symbols in your password? Y/N:Y
Do you want numbers in your password? Y/N:Y
The password is ['x', 'p', 'E', 'X', 'V', '#', ',', '@', 'q', 'N', 'F', 'U', 'b', 'W', '.']

我怎样才能使输出是这样的（在示例中使用密码）： xpEXV#,@qNFUbW.

我真的不需要知道答案，实际结果会一样，我只是超级好奇。

Answer 1

将字符与str.join() method一起加入；选择一个连接字符串并在其上调用方法，传入您的列表：

password = ''.join(password)

这将字符与空字符串 ('') 连接起来：

>>> password = ['x', 'p', 'E', 'X', 'V', '#', ',', '@', 'q', 'N', 'F', 'U', 'b', 'W', '.']
>>> ''.join(password)
'xpEXV#,@qNFUbW.'

对于其他用途，您可以选择不同的连接器：

>>> '->'.join(password)
'x->p->E->X->V->#->,->@->q->N->F->U->b->W->.'
>>> '...'.join(password)
'x...p...E...X...V...#...,...@...q...N...F...U...b...W....'
