I have already create tkinter window in which i am having a TypeError : not enough arguments to format string

What I have tried:

def update():

    a = Emp_NO.get()
    b = Name.get()
    c = Address.get()
    d = Attendance.get()
    e = Bank_Name.get()
    f = Account_NO.get()
    g = Basic_Pay.get()
    h = Net_Pay.get()

    # Create a database or connect to one
    mydb = pymysql.connect(host="localhost",user="root",passwd="mypasswd",db="mydb")
    # Create cursor
    mycursor = mydb.cursor()
    
    sql = "UPDATE Payslip SET Emp_NO=%s , Name=%s , Address=%s , Attendance=%s , Bank_Name=%s , Account_NO=%s , Basic_Pay=%s , Net_Pay=%s WHERE Emp_NO=%s"


     val = (a,b,c,d,e,f,g,h)

    mycursor.execute(sql,val)
    
    #Commit Changes
    mydb.commit()

    #Close connection
    mydb.close()

    editor.destroy() #to disappear the update window

Python

sql = "UPDATE Payslip SET Emp_NO=%s , Name=%s , Address=%s , Attendance=%s , Bank_Name=%s , Account_NO=%s , Basic_Pay=%s , Net_Pay=%s WHERE Emp_NO=%s" # 9 placeholders

val = (a,b,c,d,e,f,g,h) # 8 parameters

As the error says, you haven't provided enough parameters.

You could append the Emp_NO parameter a second time:

Python

val = (a,b,c,d,e,f,g,h,a)

But it doesn't make sense to update a column to the same value it's already set to.

Python

sql = "UPDATE Payslip SET Name=%s , Address=%s , Attendance=%s , Bank_Name=%s , Account_NO=%s , Basic_Pay=%s , Net_Pay=%s WHERE Emp_NO=%s"

val = (b,c,d,e,f,g,h,a)
