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.
Riding a bike is a lot of fun and great exercise for kids. Learning to ride a two-wheeled bicycle without training wheels is also an important milestone for kids. At what age will your child learn to ride a bike? Children usually learn to ride a bike sometime between the ages of 3 and 8, with an average of just over age 5.
