Accessing Security Holdings Information (QP->QC Migration)

I desparately need help replacing my Quantopian language with QuantConnect language. Can anyone advise how I can replace items 1 through 5 below? See the log below the code to see the result.

#The following code has been adapted to ask the above question in forum.
for stock in context.portfolio.positions:
avg_price = context.portfolio.positions[stock].cost_basis
shares_qty = context.portfolio.positions[stock].amount
total_cost = avg_price * shares_qty
context.do[stock] = 1
print "1-" #Identifier to aid with reading log.
print context.portfolio.positions #Outputs dictionary, with info on stock and related info
print "2-"
print context.portfolio.positions[stock].cost_basis # Average cost per share for stock.
print "3-"
print context.portfolio.positions[stock].amount # Number of shares owned of this stock
print "4-"
print context.portfolio.positions[stock].last_sale_date #When did this position open? (my algo only opens and closes, no rebalancing, so it will be the date when position opened)
print "5-"
print context.portfolio.portfolio_value #Whats the total account value? = Cash + Current value of positions.

2017-07-24 08:45 PRINT {Equity(3496 [HD]): Position({'last_sale_date': Timestamp('2017-07-21 14:01:00+0000', tz='UTC'), 'amount': 24, 'last_sale_price': 146.6, 'asset': Equity(3496 [HD]), 'cost_basis': 146.42667096119587})}

(bump) Can anyone offer advice on this? If you are reading this, but don't have time to answer right now, can you advise a simple yes, no, or sort-of, on whether the replacement (Python) code exists?

I can't help with Python specifically, but have a look at the class SecurityHolding accessible from Portfolio property of algorithm. In C# I can e.g. do

Log("Average cost of SPY: " + Portfolio["SPY"].AverageCost);

Search for SecurityHolding and SecurityPortfolioManager here, I couldn't get correct links to them for some reason:

 the SecurityHolding class is the core model under the surface. You can see all the supported properties on there: this is a link to the class -
