用户登录后如何存储/打印用户 ID/用户名？

Question

I want to store userid in a variable after the users logged in and I am not sure how to do that. I used getpass.getuser() , but it gives me the username from my computer system. Does session work in tkinter? Can somebody give me an idea how should I approach this? The user id is increased automatically for new user

class data:
    def checks(name, password):
        conn = sqlite3.connect('login.db')
        cur = conn.cursor()
        if cur.execute('SELECT * FROM user WHERE name = ? AND password = ?', (name, password)):
            if cur.fetchone():
                window.destroy()
                login_backend.back()
            else:
                messagebox.showinfo('error', 'Username and password is wrong')
def login_student(self):
          if len(self.namee.get()) == 0 or len(self.password1e.get()) == 0:
                     messagebox.showinfo("ERROR", "Mandatory Field is empty")
          else:
            data.checks(self.namee_text.get(), self.password1e_text.get())

Do you want to get a password and user name on the command line? If so, the secure way to do this is with getpass.getpass(). This will prompt the user. getpass.getuser(), as you discovered, is for the system user.

You don't want to print the password on the command line because of the security risk. Generally, you want to consume the sensitive credentials only as long as needed to access the resource.
