This may be happening with other numbers, but I got weird results with the modulus and division operators, after I imported the math module. I tried to do 7/200 and got 0, and 200%7 yielded 7, an impossibility with modulus. |

The result of 7 / 200 is easy to explain -- this is how integer division works in Python 2. (To get a floating result, one of the numbers must be a float.) 200 % 7 giving 7 however is strange. Are you sure this is what you calculated? |

Which version of python? Could you run this from the command line and paste the complete session, including the version info that python prints on startup? |

Seconding Eric's comment. This is what I get on my machine; can you cut and paste the equivalent output on yours (including whatever else is required to reproduce the results you describe) Python 2.6.1 (r261:67515, Feb 11 2010, 15:47:53) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> 200 % 7 4 In any case, please let us know which version of Python you're using, and where you got it from. |

The bug title interestingly says "7%200", which does result in 7. I therefore think the OP just confused the order of operands for "%". |
