[python] Something neat

[Raknarg]

This didn't seem to fit anywhere in the python section, but apparently this is valid:

True = False

Now True will equate to False.

[Tony]

although

code:

>>> True = False >>> print True False >>> print 1==1 True

[Raknarg]

How strange. Any idea how this is?

[Tony]

there's a difference between "True" the variable and "True" the value. It kind of looks like there's a variable called True and it initially holds a value that has a string representation of "True".

[Raknarg]

Right, I was thinking something along that, maybe it was a built in function that returns true

Not a function, its an object of type bool.The object has a value of True in expressions but as Tony says it has a string representation (what you see when you print it) of 'True'.
You can see this

Python:

>>> int(True) 1 >>> type(True) <type 'bool'> >>> type(True.__repr__()) <type 'str'> >>> True.__repr__() 'True'

EDIT: Interesting note, True = False is illegal in python 3 (at least in my version). It seems that they are now keywords.

Ah. Thanks for that.
