hi guys/gals...got a basic question that i can't get my hands around. i'm trying to programatically create/use a list/tuple (or whatever the right phrase in pyton is!!) basically, something like: foo = [] foo.append('cat') foo.append('dog') foo[1] = [] (and in this case, i really want to have a list called 'cat' to be created!!)
This doesn't "create a list called 'cat', it replaces the second element (remember, sequences are zero-based) of list 'foo' with an empty list.
when i've tried this, i don't get a list called 'cat', instead (as i expected) the foo[1] is now a [] (list)) so foo is now ['cat', [] ]
Indeed.
ultimatelly , i want to be able to dynamically create a number of lists that i name/create/manipulate on the fly, within the test app. ie, be able to then create a list/array cat = ['a','b','c',....] a dict doesn't seem to work, as it is essentially a series of key/values, which isn't exactly what i want...
Why do you think it's not what you want ? lists = dict() lists['cat'] = [] lists['cat'].extend(['a', 'b', 'c', 'd'])
thoughts/comments/code samples would be reatly appreciated.
Please provide more informations about your use case. -- http://mail.python.org/mailman/listinfo/python-list
