Defining a simple object

Create a file stock.py and define the following class:

class Stock: def __init__(self, name, shares, price): self.name = name self.shares = shares self.price = price def cost(self): return self.shares * self.price

Once you have done this, run your program and experiment with your new Stock object:

Note: To do this, you might have to run python using the -i option. For example:

python3 -i stock.py

>>> s = Stock('GOOG',100,490.10) >>> s.name 'GOOG' >>> s.shares 100 >>> s.price 490.1 >>> s.cost() 49010.0 >>> print('%10s %10d %10.2f' % (s.name, s.shares, s.price)) GOOG 100 490.10 >>> t = Stock('IBM', 50, 91.5) >>> t.cost() 4575.0 >>>
