Flash is not working in flask

[sahilsiddharth]

my question here
I am doing a query from Mysql database and then flashing that value on the front-end. But that variable is not appearing

my code here

x=c.execute("SELECT TELLER_ID from TELM where email=(%s)", (email,))

c.close()
conn.close()

flash("The User ID is (%s)", (x) )

---It is showing output as "The User ID is (%s)"
