Dear all,
I'm a newbie in python and would be acknowledge if somebody could shed
some light on associative arrays.
More precisely, I would like to create a multi-dimensional associative
array. I have for example a list of students which are identified
uniquely by their student IDs. Additionally, for each student I have
some information: FirstName, LastName, etc.
The array would have then the following form:
[StudentID] => [FirstName][LastName][Telephone]...[ ... ]
I would like to be able to access a field directly by using a
StudentID
[StudentID][FirstName]
[StudentID][LastName]
How could I manipulate such an array (create the array, add elements,
access data)?
Best wishes
Create a class for student with attributes for ID, FirstName, LastName, etc.
class Student:
def __init__(self, id, FirstName, ...):
self.id = id
self.FirstName = FirstName
...
then whenever you create a student object, use a dictionary to associate
the object with its is
AA = {} # An empty dictionary
s = Student(...)
AA[s.id] = s
... and repeat for many students...
Then to access a student's object given an id:
s = AA[id]
print s.id, s.FirstName, s.LastName, ...
I'd *not* call this a multi-dimension association, but rather just an
association between student objects and their ids.
Hope that helps,
Gary Herron
