Course Summary
Python Fundamentals is a 4-day training course in the Python language and its many applications. The course covers the language itself, explains object-oriented as well as functional programming techniques, error handling, packaging, system and network programming, many of the Python extensions (libraries), as well as best practices. All concepts are explained through hands-on examples and exercises, so students learn by coding in Python.Duration
4 days.
Objectives
Upon completion of this course, you will be able to:
- Develop complex programs in Python
- Understand the best use-case applications for Python
- Use Python's modules for text and XML processing, networking, system process control, database/LDAP/HTTP communication, etc.
- Design your code in both object-oriented and procedural fashion using best practices
- Handle errors in Python
- Write lean Python code
Audience
This course is designed for programmers who need to develop software in Python as well as system administrators who wish to take advantage of Python's simple scripting abilities to automate back-end tasks.
Students should have some prior programming experience and be familiar with basic concepts such as variables/scopes, flow-control, functions, modularization, error handling, TCP/IP networking, and so forth.
Familiarity with object-oriented programming language (such as Java or C++) and/or scripting languages (such as Perl or Bash shell scripting) can be helpful.
Additional Notes
This course can be taught on most major operating systems, which support Python, such as Windows, Linux, Mac OS X, etc.
