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.
Forget training wheels and other funky gadgets. All you need is a child who's ready to learn; a bike; a gently sloping, grassy hill; and a wrench. There's no set age for taking off on two wheels, but usually by 4 or 5 years of age children have enough balance and coordination.ow to Learn to Ride a Bike in 15 Minutes. If you've got two wheels and 15 minutes, you can teach your child to ride a bike.
