Tkinter SQlite – Search Function not working

Good evening,

This is a simple function reading the value of an entry widget and searching in the database for it. It won´t run.
Could someone kindly point me to my rookie mistake?

This is the Function:

def find_search_term(self, search_term):
    search_term = self.search_entry.get()
    conn=sqlite3.connect("KTRmini.db")
    c = conn.cursor()
    c.execute("SELECT * FROM KTRmini_table WHERE discription LIKE "%search_term%",")
    data=c.fetchone()[0]
    print(discription)
    conn.close()

This is the Error:

c.execute("SELECT * FROM KTRmini_table WHERE discription LIKE "%search_term%",")
TypeError: not all arguments converted during string formatting

>Solution :

c.execute("SELECT * FROM KTRmini_table WHERE discription LIKE %?%", search_term)
