frange(), a range function with float increments (Python recipe) by Dinu Gherman ActiveState Code (http://code.activestate.com/recipes/66472/) Sadly missing in the Python standard library, this function allows to use ranges, just as the built-in function range(), but with float arguments. All thoretic restrictions apply, but in practice this is more useful than in theory.
When I worked at a daycare we would have bike day during the summer when kids, aged 3-5, could bring in their bikes and ride them, most of the kids were on big bikes with training wheels and a few of the 4-5 year olds were without training wheels.
If you are a cyclist in the Bay Area, we strongly encourage you to take the following steps to prevent accidents. 1  Wear a helmet. All children under the age of 18 in California must wear a helmet when riding a bicycle. 2  Equip your bike. Cyclists should equip their bikes with mirrors to assist with safe lane changes. 3  Wear bright gear.
