        cur.execute(insrt,sql1)
    insrtDirector(uuid.uuid4(), (SELECT "UName" from University WHERE "UName" = 'University College London') , (SELECT "DName" from Department WHERE "DName" ='English') , 'Christopher (3)', 'Nolan (3)', 1970, 'Westminster, London, United Kingdom' )

 insrtDirector(uuid.uuid4(), (SELECT "UName" from University WHERE "UName" = 'University College London') , (SELECT "DName" from Department WHERE "DName" ='English') , 'Christopher (3)', 'Nolan (3)', 1970, 'Westminster, London, United Kingdom' )
                                        ^^^^^^^
SyntaxError: invalid syntax

Answer

You need to properly use subqueries (google it!). Try something like this, it might work (and please fix your variable names, qwertyu is not good, should be descriptive like unique_id, uname, dname, first_name, etc.)

def insrtDirector(q,w,e,r,t,y,u):
    # Assume w and e are always subqueries with one result
    # Also assume no outside source can supply w and e (must be sanitized to not be subject to sql injection)
    insrt = "INSERT INTO Director VALUES (%s,{uname_subquery},{dname_subquery},%s,%s,%s,%s)".format(
        uname_subquery=w,
        dmane_subquery=e,
    )
    # This print command is just temporary so you can see what it looks like
    print("insert command:", insrt)
    sql1 = (q,r,t,y,u)
    cur.execute(insrt, sql1)

insrtDirector(
    uuid.uuid4(),
    "(SELECT UName from University WHERE UName = 'University College London')",
    "(SELECT DName from Department WHERE DName = 'English')",
    'Christopher (3)',
    'Nolan (3)',
    1970,
    'Westminster, London, United Kingdom',
)
