I've just started learning Python a couple of weeks ago, and I started writing a text-based adventure game. I'm having some trouble finding a good way to convert strings into instances of a class, other than using eval(), which I've read isn't safe. For reference, here's what I'm working with:
class Room(object):
"""Defines a class for rooms in the game."""
def __init__(self, name, unlocked, items, description, seen):
self.name = name
self.unlocked = unlocked
self.items = items
self.description = description
self.seen = seen
class Item(object):
""" Defines a class of items in rooms."""
def __init__(self, name, actions, description):
self.name = name
self.actions = actions
self.description = description
def examine(input):
if isinstance(eval(input), Room):
print eval(input).description
elif isinstance(eval(input), Item):
print eval(input).description
else:
print "I don't understand that."
If input is a string, how do I safely make it a class object and access the data attribute .description? Also, if I'm going about this in entirely the wrong way, please feel free to suggest an alternative!
