two-dimensional arrays arrays are not limited to single dimension some problems require the use of two-dimensional array which organizes data into rows and columns similar to table or grid the individual elements are accessed by specifying two indicesone for the row and one for the column[ ,jfigure shows an abstract view of both oneand two-dimensional array while computer architectures provide mechanism at the hardware level for creating and using one-dimensional arraysthey do not typically support arrays of higher dimensions insteadprogramming languages typically provide their own mechanism for creating and managing arrays that consist of multiple dimensions in this sectionwe explore two-dimensional arrays while arrays of higher dimensions are discussed later in the elements rows columns figure sample arrays(lefta - array viewed as sequential list and (righta - array viewed as rectangular table or grid the array abstract data type as we saw earlierpython does not directly support built-in arrays of any dimension butin the previous sectionwe were able to use the ctypes module to create one-dimensional hardware-supported array that we used to implement the array adt two-dimensional arrays are also very common in computer programmingwhere they are used to solve problems that require data to be organized into rows and columns since - arrays are not provided by pythonwe define the array abstract data type for creating - arrays it consists of limited set of operations similar to those provided by the one-dimensional array adt define array adt two-dimensional array consists of collection of elements organized into rows and columns individual elements are referenced by specifying the specific row and column indices (rc)both of which start at array dnrowsncols )creates two-dimensional array organized into rows and columns the nrows and ncols arguments indicate the size of the table the individual elements of the table are initialized to none numrows()returns the number of rows in the - array
