I have created a list of dictionary in a format as below:

[{u'PLAN_A': True, u'PLAN_B': True, u'PLAN_C': True, u'PLAN_D': True, 
  u'PLAN_E': True, u'PLAN_F': True, 'date': u'2011-08-01', u'PLAN_G': True}
 {u'PLAN_A': True, u'PLAN_B': True, u'PLAN_C': True, u'PLAN_D': True, 
  u'PLAN_E': True, u'PLAN_F': True, 'date': u'2011-08-01', u'PLAN_G': True}]

A little explanation here:

The list contains information to check whether information regarding the investment plans is already provided for a particular month, if information is available, it will be TRUE, if not it will be FALSE
– PLAN_A is the name of an investment plan, which means there are 7 of them here
– True/False refers to whether information is entered for that particular month

I want to create a HTML output using django like the one below:

DATE    PLAN_A  PLAN_B  PLAN_C
2010-01 TRUE    FALSE   TRUE
2010-02 TRUE    FALSE   TRUE
2010-03 TRUE    FALSE   FALSE

I don’t want to hard-code the column name (i.e. PLAN_A, PLAN_B, PLANC), as there maybe increasing number of plans in the future.

I think that will be a for-loop for creating <tr> and <td>. If I am working this as R, I will rearrange the column of the dataframe to the way I like (maybe I want PLAN_A to be at the third column, but not the first column), but having known that dictionary cannot be sorted, I don’t know how to arrange the keys inside, as you can see in my dataset, the date key is at the 7th column.

Can anyone help? Thanks.

    Here’s some code that given a list in the above format (with the missing comma in the right place) produces something you can work with:

    bydate = []
planNames = set()
for d in data:
    ddict = {'date': d['date']}
    plans = d
    del plans['date']
    planNames = planNames.union(plans.keys())
    ddict['plans']=plans
    bydate.append(ddict)

    after that, ‘bydate’ is:

    [{'date': u'2011-08-01', 'plans': {u'PLAN_B': True, u'PLAN_C': True, u'PLAN_A': True, u'PLAN_F': True, u'PLAN_G': True, u'PLAN_D': True, u'PLAN_E': True}}, {'date': u'2011-08-22', 'plans': {u'PLAN_B': False, u'PLAN_C': True, u'PLAN_A': True, u'PLAN_F': False, u'PLAN_G': True, u'PLAN_D': True, u'PLAN_E': True}}]

    which you can sort by the date key. And ‘planNames’ is:

    set([u'PLAN_B', u'PLAN_C', u'PLAN_A', u'PLAN_F', u'PLAN_G', u'PLAN_D', u'PLAN_E'])

    which is a set (like a list, but unique elements) of all the plan names mentioned in the data.
