我正在做一个涉及用户名和密码输入框的项目，这两个输入框都必须是某个短语才能让用户进入程序的下一阶段。目前，当按下 PushButton 时，无论是否输入了正确的用户名和密码，用户总是会得到“对不起，您的用户名或密码不正确”的信息框，而不是成功的信息框。

到目前为止，我的程序如下。请忽略传递的变量，这对以后的事情很重要，所有的空白文本都是为了强制其他小部件进入正确的位置。

from guizero import App, Text, TextBox, PushButton, info, Picture

passed = False

def authenticate():
    if input_box1 == "a" and input_box2 == "b":
        passed = True
        info("Welcome", "Level 5 identification accepted. Welcome, Dr. Artyom.")
    else:
        info("Password", "Your username or password is incorrect.")


app = App(title="AppTest", width=900, height=600, layout="grid", bg=[255,255,255])

text = Text(app, text=" ", grid=[0,0])

text = Text(app, text="                                  ", grid=[1,1])

text = Text(app, text="Please enter a valid username and password.", grid=[2,1], color=[0,0,0])
    
text = Text(app, text="             ", grid=[2,2])

input_box1 = TextBox(app, grid=[2,3], height=1, width=25)

text = Text(app, text="Username", grid=[1,3], color=[0,0,0])

text = Text(app, text="             ", grid=[2,4])

input_box2 = TextBox(app, grid=[2,5], hide_text=True, height=1, width=25)

text = Text(app, text="Password", grid=[1,5], color=[0,0,0])

text = Text(app, text="        ", grid=[2,6])

submit = PushButton(app, enabled=True, command=authenticate, height=1, width=6, grid=[2,7])

text = Text(app, text="Submit", grid=[2,7], color=[0,0,0])

text = Text(app, text="          ", grid = [3,11])

picture = Picture(app, image="D:\python files\logtext.gif", grid=[2,12])


app.display()

我知道这有点乱，但非常感谢所有帮助。

input_box1andinput_box2是两个不同的TextBoxes，所以它们不会直接等于文本字符串。相反，您想比较它们的值：

def authenticate():
    if input_box1.value == "a" and input_box2.value == "b":
        passed = True
        info("Welcome", "Level 5 identification accepted. Welcome, Dr. Artyom.")
    else:
        info("Password", "Your username or password is incorrect.")
