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.
Choose the right size of bike. Because your child is a toddler, she should have a toddler-sized bike. If the bike is too big, your child wonât be able to reach the pedals, so take her to pick out the bike when you purchase it. To determine if the bike is the right size: Help your child to get on to the bike.
