Programming Skills: Complete the function egg_category which returns a str describing an egg's category given its int weight in grams. Here is a table specifying the weight ranges if an egg's weight is on the boundary between two category ranges, it is assigned the smaller category. Category Small Meduim Weight no more than 50 grams 50-57 grams Category Large Jumbo Weight 57-64 grams more than 64 grams def egg_category (weight): %# Return a str describing the category of an egg of the specified int weight.
