Why is 00100 = 64 in python?

Why, like in the following python code, does 00100 equal 64?

>>> i = 00100
>>> i
64
>>> type(00100)
<type 'int'>
>>> str(00100)
'64'
>>> str("00100")
'00100'
>>> int(str("00100"))
100
>>>

1 is 01, 2 is 02, ..., 7 is 07, 8 is 10 (yes!), 9 is 011, etc.

In Python (and other languages too) when a number begin with 0 is interpreted as an octal number.
