Question

我试图找出如何将散列对象存储为字符串。我有一段代码可以比较用户输入的内容与存储在Sqlite3数据库中的内容，然后允许他们访问或不访问，具体取决于用户名和密码是否正确。为了安全起见，我在数据库中对密码进行了哈希处理，并且用户输入的内容也是经过哈希处理的，它们是要进行比较的，但是当它进行检查时，它会给出shell中的行;

sqlite3-interfaceerror-error-binding-parameter-0-probably unsupported type

我被告知这是因为哈希不是字符串，所以我如何将哈希对象变成字符串？任何帮助，将不胜感激。谢谢，山姆。

此外，如果有帮助，这也是代码的完整部分。

def点击（按钮）：如果按钮==“取消”： login.stop（）

if button == "Register":
   login.stop()
   register.go()



else:
   usr = login.getEntry("Username")
   pwd = login.getEntry("Password") #collects entry of password & username

###MD5 HASHING###
pwdencypt = hashlib.md5(pwd.encode('utf-8')) #makes the encypted password using md5 hashing
print(pwdencypt.hexdigest())
pwd2 = pwdencypt

conn = sqlite3.connect("uHubDatabase.db")
cursor = conn.cursor() #connects to database

###USERNAME SECTION###
find_user=("SELECT Username FROM UserTable WHERE Username = ?") #sets the finding of the username from the database as a varaible 
cursor.execute(find_user,[(usr)])


founduser = str(cursor.fetchall())
print(founduser)
removechars = "'(),[]" #Avoids the error of special characters caused by the database outputting strings (Text)
for char in removechars:
    founduser = founduser.replace(char,'')

###PASSWORD SECTION###
find_pass=("SELECT Password FROM UserTable WHERE Password = ?") #sets the finding of the password from the database as a varaible 
cursor.execute(find_pass,[(pwd2)])

foundpass = str(cursor.fetchall())
print(foundpass)
removechars = "'(),[]" #Avoids the error of special characters caused by the database outputting strings (Text)
for char in removechars:
    foundpass = foundpass.replace(char,'')

###DATA VARIABLE CHECKS###
print("This is from Database(Username)",founduser) 
print("This is whats inputed",usr) 
print("This is from Database(Password)",foundpass) 
print("This is whats inputed",pwd)
print("This is pwd but encypted",pwdencypt.hexdigest())

if founduser == usr and foundpass == pwdencypt: # If correct
    print("SUCESS")
    login.stop()
    home.go()

else: #if incorrect
    print("FAIL")
    login.retryBox("INCORRECT LOGIN", "The Username or Password entered are incorrect. Please try again.")
print("User:", usr, "Pass:", pwd)

conn.close() #closes connection

由于某种原因，当我将代码粘贴到此处时代码不对齐所以忽略它，在我的程序中不是这种情况。导入的模块包括sqlite3和Appjar，就像tkinter。
