Unrecognized token in SQLite statement

I am inserting data from one table to another, however for some reason I get "unrecognized token". This is the code:

cur.execute("INSERT INTO db.{table} SELECT distinct latitude, longitude, port FROM MessageType1 WHERE latitude>={minlat} AND latitude<={maxlat} AND longitude>= {minlong} AND longitude<= {maxlong}".format(minlat = bottomlat, maxlat = toplat, minlong = bottomlong, maxlong = toplong, table=tablename))

This translates to the following, with values:

INSERT INTO db.Vardo SELECT distinct latitude, longitude, port FROM MessageType1 WHERE latitude>=69.41 AND latitude<=70.948 AND longitude>= 27.72 AND longitude<= 28.416

The error code is the following:

sqlite3.OperationalError: unrecognized token: "70.948 AND"

Is the problem that there is three decimal points?

This is the create statement for the table:

cur.execute("CREATE TABLE {site} (latitude, longitude, port)".format(site = site))
