Question

I m writing a console program with Python under Windows.
The user need to login to use the program, when he input his password, I d like they to be echoed as "*", while I can get what the user input.
I found in the standard library a module called getpass, but it will not echo anything when you input(linux like).
Thanks.

。你们可以很容易地加以修改,以便做到这一点。事实上,这里是一份经过修改的“getpass.win_getpass()文本,你可以将其贴在你的法典中:

import sys

def win_getpass(prompt= Password:  , stream=None):
    """Prompt for password with echo off, using Windows getch()."""
    import msvcrt
    for c in prompt:
        msvcrt.putch(c)
    pw = ""
    while 1:
        c = msvcrt.getch()
        if c ==  
  or c ==  
 :
            break
        if c ==  03 :
            raise KeyboardInterrupt
        if c ==   :
            pw = pw[:-1]
            msvcrt.putch(  )
        else:
            pw = pw + c
            msvcrt.putch("*")
    msvcrt.putch( 
 )
    msvcrt.putch( 
 )
    return pw

You might want to reconsider this, however. The Linux way is better; even just knowing the number of characters in a password is a significant hint to someone who wants to crack it.

友好的答案是很接近的,但问题在于后天空,不能抹掉星号,而后天空能够回落到投入之外。

Try:

def win_getpass(prompt= Password:  , stream=None):
    """Prompt for password with echo off, using Windows getch()."""
    if sys.stdin is not sys.__stdin__:
        return fallback_getpass(prompt, stream)
    import msvcrt
    for c in prompt:
        msvcrt.putwch(c)
    pw = ""
    while 1:
        c = msvcrt.getwch()
        if c ==  
  or c ==  
 :
            break
        if c ==  03 :
            raise KeyboardInterrupt
        if c ==   :
            if pw ==   :
                pass
            else:
                pw = pw[:-1]
                msvcrt.putwch(  )
                msvcrt.putwch(" ")
                msvcrt.putwch(  )
        else:
            pw = pw + c
            msvcrt.putwch("*")
    msvcrt.putwch( 
 )
    msvcrt.putwch( 
 )
    return pw

注 put不与 p2.x合作,你需要使用 m。相反。

您可使用<条码>。这并没有确切地回答这个问题,因为绕行功能不给青少年带来任何结果,除非是迅速的。其原因是它增加了安全等级。如果有人看着你的肩子,那么他们就能够说出你的口号是多长的。

这里的例子就是如何使用:

from getpass import getpass
getpass( Enter your password:  )

这个例子将显示“你的密码:”,然后,你可以打上你的密码。
