what's wrong with my setEchoMode code

I create a QLineEdit in PyQt, and i want to hide or show the charactor of password, so i use the code below
Here is my login_ui py file Attachment 11205, you can use it to test my code within the py or import it from other py.

Code:

---

#in the init function, ck_pwd and ck_pay_pwd are QCheckBox, password and pay_password are QLineEdit
def init(self):
    QtCore.QObject.connect(self.login_ui.ck_pwd, QtCore.SIGNAL("stateChanged(int)"), lambda : self.show_or_hide_pass(self.login_ui.password))
    QtCore.QObject.connect(self.login_ui.ck_pay_pwd, QtCore.SIGNAL("stateChanged(int)"), lambda : self.show_or_hide_pass(self.login_ui.pay_password))
 
 
def show_or_hide_pass(self, password_obj):
    if password_obj.EchoMode()!=QtGui.QLineEdit.Normal:
        print 'normal'
        password_obj.setEchoMode(QtGui.QLineEdit.Normal)            
    else:
        print 'password'
        password_obj.setEchoMode(QtGui.QLineEdit.Password)

---

but in the function show_or_hide_pass, the password_obj.EchoMode() always be the 0 (value of QtGui.QLineEdit.Normal), it doesn't make any sense.
what's wrong with my code, Is there somebody can help?

Line 8, the property name is echoMode() not EchoMode().

oh, what a fuck!!
that is the problem.
thanks a lot

Perhaps PyChecker or Pylint would have flagged this for you.
