Check each item in the overall list like this: # in an external method if type(item)==type([]): print "it's a list" # in a Python Script if same_type(item,[]): print "it's a list" -----Original Message----- From: Dianne Van Dulken [mailto:Dianne.VanDulken@team.ozemail.com.au] Sent: Monday, 16 September 2002 2:24 p.m. To: 'zope@zope.org' Subject: [Zope] ZClass question - array of arrays Hi, I'm having a little bit of a problem working out what ZClass property I should be setting. I want to record an array that can either contain strings or more arrays. eg: It can be ['a', 'b', 'c'] or ['a', ['b', 'c'], 'd'] or [['a','b'], ['c','d'], ['e','f']] The problem is that I can't work out what property type I should be setting this to be. I tried tokens, but tokens won't allow arrays to be saved, and both lines and strings assume that there will be a string (obviously), which means that I have to do a lot of splitting on [ and , before I can work with the data. The whole idea of the property is that if there is a scalar in position X, it shows the scalar, otherwise with an array, it shows a random value from that array. Is there an obvious type that I am missing?
