Updated my code to this:
curr.pgsql.execute('''
INSERT INTO my_table(name, age)
SELECT %s, %s
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name= name)
''', ('Scott', 23))
If I remove SELECT statement, I will get an error message: error : psycopg2.ProgrammingError: syntax error at or near "WHERE"
LINE 12: WHERE NOT EXISTS
Trying to coordinate with Lead Dev about adding Index On The Fly
I tried to figure how to make this work and could not, so I led you down a false path.

What I tried is
'''INSERT INTO my_table(name, age)
SELECT %s, %s,
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name=%s)''', ('Scott', 23, 'Scott'))
How about:
'''INSERT INTO my_table(name, age)
VALUES( %s, %s)
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name=%s)''', ('Scott', 23, 'Scott'))
