Python addresses these problems and makes a compelling language for algorithms education. First, its indentation-based syntax is so similar to most textbooks that even students without much programming background have no trouble coding up algorithms just by following the book.Many useful algorithms are recursive in structure, i.e., to solve the given problem, they call themselves recursively one or more times to deal with closely related sub-problems. These algorithms typically follow a divide-and-conquer algorithm. The divide and conquer algorithm involves three steps at each level of recursion.Regarding to the order book, what you can do is create a simple two dimensional array. ask [price] [secondOfTheDay] = volume. This might not be very memory effective but usually it is enough if you play with it. if you make the first dimension (price) dynamic you would simply create the time arrays on the fly. The first step in learning Python is to see the Python equivalent of a Blockly program.
