Yes, True is an integer with value 1. Actually True is a bool but bool
is a subclass of int:
In [3]: type(True)
Out[3]:
In [4]: isinstance(True, int)
Out[4]: True
In [5]: int(True)
Out[5]: 1

Right, because 5 != 1

On a slightly different tangent from the other answers you've received
to this question, if you're using a conditional expression, don't
compare it explicitly with True or False, just state the condition:
if 2 in [1,2,

Well said, Kent.
Here's a generic tip to anyone learning Python.
I learned Python after working professionally with several languages
for many years, including Java

That's good news. I'd be worried if this wasn't the desired behaviour

No, not a bug. Don't be too quick to blame your tools!
The equivalent expression is
In [1]: (2 in [1,2,3]) and ([1,2,3]==False)
Out[1]: False
'in' is conside
Dear Python folks,
here is a sequence of commands (ipython) that lead to a question.
See my comments after leading '#':
In [1]: 2 in [1,2,3]
Out[1]: True
#nothing special here, of course 2 is in the list.
In [2]: 2 in [1,2,3] == True
Out[2]: False
#This is somewhat surprising, as one would ho
