speed) but whose functions have the interfaces of a Python module (which lets us call it from Python). 10 Python arrays: lists of lists a 00 a 01 a 02 a 10 a 11 a 12 [ [ , , ] , [ , , ] ] a ... So our array is treated in Python as a list of rows. Each of those rows is a list of the values in that row. This makes it …

number (element) in an array: y = sin (x) This is an e cient way to do calculations in Python, but sometimes we need to do something more complicated on each element separately.
