    Nice one, thanks Steve
    Definitely time to dust off those old Python skills

    Easy one for me. Here is something cool to think about how list and dicts can work together.


    # Two dictionaries with two sets of rows and columns
    dictA = {'CustomerID': [1, 2, 3, 4, 5],  'FirstName': ['John', 'Joe', 'Sarah', 'Jane', 'Sam']}
    dictB = {'CustomerID': [1, 2, 3, 4, 5],  'FirstName': ['Sue', 'Aiden', 'Stephanie', 'Steve', 'Faye']}

    # List of my dictionaries
    myList = [dictA, dictB]

    # Being our dictionaries contain the same field names, we can use a list to help us keep track of each dict and iterate over them.
    # We can then use a forloop to iterate and list out each list within each dict.
    for records in myList:
         for customers in records['FirstName']:
              print customers

    Course, you could just combine the dicts too. But it's interesting to think about how they can be separate and reference each other too.

    I've never used python, so I guessed.  I guessed poorly.

    I've never used python, so I guessed.  I guessed poorly.

    I've never used it either,  but I have read odd bits of python code here and there (helping someone find his silly errors) and had a vague memory of hash tables being called dictionaries and using square brackets for keys.
    My son tells me I should learn the language, but I'm not convinced.
