我遇到以下问题，当 python 脚本运行时，用户在命令窗口上一直按“回车键”...以下是在命令窗口上运行的内容，但用户一直按回车键，最终输入密码和脚本失败，我该如何防止这种情况？

  **Password: //asks for password but user had multiple enter key presses above which is taken as passoword and fails**

Python代码：-

url='http://wiki.com/'+wikiName+'/w/index.php?title='+hId +'_'+rId+'&action=edit'
cookiehand = urllib2.HTTPCookieProcessor()
password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_mgr.add_password(user=getpass.getuser(),passwd=getpass.getpass(),uri=authhost,realm=realm)
auth_handler = urllib2.HTTPBasicAuthHandler(password_mgr)
opener = urllib2.build_opener(auth_handler, cookiehand)
urllib2.install_opener(opener)
# make the request
req = urllib2.Request(url=url)
try:
    f = urllib2.urlopen(req)
    txt = f.read()
    f.close()
except urllib2.HTTPError, e:
    txt = ''
    print 'An error occured connecting to the wiki. No wiki page will be generated.'//eventually gets this error

您需要做的是验证输入。像这样的东西：

user = ""
pass = ""

while not user and not pass:
    user = getpass.getuser()
    passwd = getpass.getpass()

请注意，如果允许使用空白密码，这将不起作用。如果您可以控制 getpass 库，则将验证移到这两个方法中可能更有意义，并且可能使用默认参数使它们成为可选参数，例如validate=False
