Python 3 ... Blocks of Stock. A block of stock as a number of attributes, including a purchase date, a purchase price, a number of shares, and a ticker symbol. We can record these pieces of information in a tuple for each

block of stock and do a number of simple operations on the blocks.

Consider the following portfolio.

We can represent each block of stock as a 5-tuple with purchase date, purchase price, shares, ticker

symbol and current price.

portfolio= [ ( "25-Jan-2001", 43.50, 25, 'CAT', 92.45 ),

( "25-Jan-2001", 42.80, 50, 'DD', 51.19 ),

( "25-Jan-2001", 42.10, 75, 'EK', 34.87 ),

( "25-Jan-2001", 37.58, 100, 'GM', 37.58 )

]

Develop a function that examines each block, multiplies shares by purchase price and determines the

total purchase price of the portfolio.

Develop a second function that examines each block, multiplies shares by purchase price and shares by

current price to determine the total amount gained or lost.
