Stocks X43847

Statement

Write a function @total_stock(stk1, stk2)@ that provided two product stocks returns the total stock. Each stock is a dictionary whose keys are strings representing product codes (or product names) and values are integers representing the number of available units. For instance, the dictionary $\{'orange':5, 'lemon':2, 'tangerine':1\}$ represents a stock of five oranges, two lemons and one tangerine.

>>> stock_alice_bob = total_stock(stock_alice, stock_bob)
>>> stock_alice_bob == {'tangerine': 2, 'orange':11, 'lemon':2, 'apple':3}
