This behaviour is shared by all programming languages that use floating point numbers. For example, this is Ruby:

    [steve@ando ~]$ irb
    irb(main):001:0> 10 * 3.14 == 31.4
    => false
    irb(main):002:0> 10 * 3.14 - 31.4
    => 3.5527136788005e-15

It's not a bug in Python or even in floating point numbers. See the link in the tutorial that xtreak gave and the FAQ
