Python, MySQLdb and escaping table names?

Question

I may be missing something obvious, but I can\'t figure out how my code is different from various examples I see in the online documentation for MySQLdb.

Interesting. But in the manual there are a couple of examples. Maybe it is something similar.

c=db.cursor()
max_price=5
c.execute("""SELECT spam, eggs, sausage FROM breakfast
          WHERE price < %s""", (max_price,))

In this example, max_price=5 Why, then, use %s in the string? Because MySQLdb will convert it to a SQL literal value, which is the string '5'. When it's finished, the query will actually say, "...WHERE price < 5".

And

c.executemany(
      """INSERT INTO breakfast (name, spam, eggs, sausage, price)
      VALUES (%s, %s, %s, %s, %s)""",
      [
      ("Spam and Sausage Lover's Plate", 5, 1, 8, 7.95 ),
      ("Not So Much Spam Plate", 3, 2, 0, 3.95 ),
      ("Don't Wany ANY SPAM! Plate", 0, 4, 3, 5.95 )
      ] )

Here we are inserting three rows of five values. Notice that there is a mix of types (strings, ints, floats) though we still only use %s. And also note that we only included format strings for one row. MySQLdb picks those out and duplicates them for each row.
