psycopg2.errors.SyntaxError when instantiating a postgres database

Question

Here is the code

import os
import psycopg2

conn = psycopg2.connect(
host="localhost",
database="postgres",
user=os.environ['DB_USERNAME'],
password=os.environ['DB_PASSWORD'])


cur = conn.cursor()


cur.execute('DROP TABLE IF EXISTS user;')
cur.execute('CREATE TABLE user (id serial PRIMARY KEY,'
                                  'email varchar (100) UNIQUE,'
                                  'password varchar (100) NOT NULL,'
                                  'name varchar (1000) NOT NULL);'
                                 )
 
conn.commit()
 
cur.close()
conn.close()

and here is the error i'm getting

Traceback (most recent call last):
  File "/testApp/app/init_db.py", line 14, in <module>
    cur.execute('DROP TABLE IF EXISTS user;')
psycopg2.errors.SyntaxError: syntax error at or near "user"
LINE 1: DROP TABLE IF EXISTS user;

Do you have any ideas on why am i getting this error? I really can't see where is the syntax error. Thanks
