1 Introduction to Python Python1 is a general-purpose, high-level programming language, which is widely used in scienti c computations when performance is not a factor. This course will be taught using the python programming language. Most problems are expected to be solved by writing python programs, and examples will be given in python.

The simplest way to represent vectors in Python is using a list structure. A vector is constructed by giving the list of elements surrounded by square brackets, with the elements separated by commas. The assignment operator =is used to give a name to the list. The len()function returns the size (dimension). In [ ]: x=[-1.1,0.0,3.6,-7.2] len(x) Out[ ]: 4 Some common mistakes. Don’t forget the ...

To distinguish between scalars and vectors we will denote scalars by lower case italic type such as a, b, c etc. and denote vectors by lower case boldface type such as u, v, w etc. In handwritten script, this way of distinguishing between vectors and scalars must be modified. It is customary to leave scalars as regular hand written script and ...
