what is this error?

[shahram555]

c={'a':1,'b':2}
c.has_key('a')

Traceback (most recent call last):
File "<pyshell#3 2>", line 1, in <module>
c.has_key('a')
AttributeError: 'dict' object has no attribute 'has_key'


Why does this fail?

[bvdet]

>>> c={'a':1,'b':2}
>>> c.has_key('a')
True

I can't explain it. 'has_key' is a read-only attribute of a dict object.

What version of Python are you useing? has_key() was removed in Python3.x I think. Use "in",

c={'a':1,'b':2}
print 'a' in c
