Python for Scientists and Engineers
Dates for Open Courses
|Leipzig||Python for Scientists and Engineers||10.06.-12.06.2013|
Also available as in-house course.
Scientists and Engineers with basic knowledge of Python. This course can be combined with introductory courses (see Recommended Module Combinations) to achieve appropriate Python skills.
Many problems that scientists and engineers need to solve require some kind of programming. Python is getting increasingly popular among this kind of users. One reason is the relatively little effort compared to the results. For people who only program occasionally Python is also a good choice. Even after a longer time without touching Python source it can still be read and understood with little effort.
Overview of scientific and technical libraries for Python
There is a great variety of Python libraries for scientific purposes. A short overview is presented and selected example libraries are briefly introduced.
Numerical Calculations with NumPy
The library NumPy is the defacto standard for the work with arrays and linear algebra.
Array-Construction and Array-Properties
There are different ways to construct arrays with NumPy. The most useful way to create an array for a specific purpose is demonstrated with examples. The properties of array objects are explained.
In contrast to Python data types that are dynamically determined at run time, data types of NumPy arrays have to be explicitly specified. This is one prerequisite to achieve the speed advantages of NumPy compared to pure Python. There are considerably more data types in NumPy than in Python. The course covers the usage of those data types and in particular their correspondence with C data types.
Slicing and Broadcasting
The technique of slicing allows read and write access to arbitrary parts of arrays. Since it works with multidimensional arrays it often allows for short and elegant programs without loops. Experience shows that the first steps with slicing need getting used to it. Therefore, numerous exercises are included in the course to cover different types of applications.
The so called broadcasting is applied in NumPy for arrays with different shapes when thy are used in computations. Missing parts of arrays are filled in if possible. A good understanding of this mechanism is a basic requirement for an effective work with NumPy.
NumPy allows to apply many operations on whole arrays independent from their dimensions. Examples are use to demonstrate the usage of these universal functions.
NumPy provides basic functionality for solving problems in numerical algebra. Examples are used to demonstrate its usage.
Storage and Processing of Large Amounts of Data
Applications in the scientific and engineering domain often have to deal with large amounts of data. There are several ways to store data in Python. Some of them are presented in the course.
The simplest way to store data is the use of ASCII files. It is shown how ASCII files can be read and written efficiently. Techniques for conversion of column based data in Python data structures are given.
Many data are stored in Excel files. Python offers several ways of reading and writing data in Excel files. Access via Microsofts COM interface are applied as well as direct binary reading and writing of files as a platform independent solution.
The file format NetCDF can be used to store large amounts of array data up to several terabytes. Python offers an interface for NetCDF. Its handling will be covered in the course.
The HDF5-Format is used for very similar purposes as the NetCDF-Format. In fact, the new version, NetCDF4, is based on HDF5. HDF stands for hierarchical data format and offers better opportunities to organized data. The module PyTables offers a mature and comfortable interface to HDF. In the course examples for it are given.
Frequently, data are stored in databases. Python offers a uniform API for accessing all major databases. The use of this API is taught in the course.
Pickling and Shelving
Python offers ways to conveniently store Python objects with the built-in modules pickle and shelve. Complex data structures can be stored on disk for later usage without the need to come up with a file format for storage. Application as well as advantages and disadvantages are presented in the course.
Objectoriented Programming for Scientific and Technical Projects
The object-oriented paradigm is currently prevailing in software engineering. Many scientists and engineers are more familiar with procedural programming. The course uses examples to show that object orientation can be advantageous also for typical scientific or engineering problems.
Graphical Presentation of Scientific Data
Results of scientific and technical calculations regularly need to be presented graphically. Although there are many applications available an automated production of graphics can be especially useful if many graphics need to be produced or the same graphics needs to be frequently updated.
The library matplotlib provides many different types of diagrams from within Python with only a few lines of code. Examples are used to exercise the use of this library.
Three-dimensional visualization and animation can be easily achieved with MayaVi. The standalone usage is taught in the course as well as the automation from within a Python program.
Application Integration with Python
Python is often termed as "glue language" because it proves to be especially useful for the connection of heterogeneous applications. This features makes it particularly attractive tool for scientific and technical tasks. Several different possibilities to connect very different applications into one uniform program are shown in the course.
Open Time for Solving Participant's Problems
The participants are asked before the course to provide tasks that they usually need to solve at work. Solution strategies with Python are attempted in the course.
The participants can follow all steps directly on their computers. There are exercises at the end of each unit providing ample opportunity to apply the freshly learned knowledge.
Every participant receives comprehensive printed materials that cover the whole course content as wells a CD with all source codes and used software.
