[web2py] How to call a Table using a variable? db.VarName.update_or_insert(school_name = 'ABC High School')

[Alberto Plata]

I have a table,   db.define_table('schools', Field('school_name', 
'string')).  I've been adding data to the table by,    
db.schools.update_or_insert(school_name = 'ABC High School'). 
My question is... Is there anyway I can call my 'schools' table with a 
variable?? As an example, when I try:

school_table_variable = 'schools'
db.school_table_variable.update_or_insert(school_name = 'ABC High School')

The program crashes. Is there a way around this?
