input: Write a function to convert a given SQL query to its equivalent Python code using SQLite3. The function should take the SQL query as a string input, connect to a SQLite database named 'movies.db', execute the query, fetch all results, print each row, and then close the connection. The function should return None.
  assert convert_sql_to_python("SELECT * FROM Movies WHERE category = 'horror'")==None
  assert convert_sql_to_python("SELECT title FROM Movies WHERE rating > 8.5")==None
output: def convert_sql_to_python(sql_query):
      import sqlite3
      conn = sqlite3.connect('movies.db')
      cursor = conn.cursor()
      cursor.execute(sql_query)
      rows = cursor.fetchall()
      for row in rows:
          print(row)
      conn.close()
      return None
