Mastering Python Programming (with Advanced Topics)

Gain In-Depth Core Python Skills | Learn File Operations, Regular Expressions, Binary Data, Network Services & More

Duration:

5 days

Audience:

Experienced Programmers and Systems Administrators that are employees of federal, state and local governments; and businesses working with the government.

This course is appropriate for advanced users, system administrators and web site administrators who want to use Python to support their server installations, as well as anyone else who wants to automate or simplify common tasks with the use of Python scripts.

Students should have basic development experience in any programming language, along with a working, user-level knowledge of Unix/Linux, Mac, or Windows.

Training Overview:

Geared for experienced users, Mastering Python Programming is an introductory and beyondlevel practical, hands-on Python training course that leads the student from the basics of writing and running Python scripts to more advanced features such as file operations, regular expressions, working with binary data, and using the extensive functionality of Python modules. Extra emphasis is placed on features unique to Python, such as tuples, array slices, and output formatting.  This comprehensive, practical course provides an in-depth exploration of working with the programming language, not an academic overview of syntax and grammar.  Students will immediately be able to use Python to complete tasks in the real world.

Course Topics Covered:

Throughout the course, students will explore and learn about:

  • Running Python Scripts
  • Getting Started
  • Flow Control
  • Sequence Data
  • Defining Functions
  • Working with Files
  • Dictionaries and Sets
  • Errors and Exception Handling
  • Using Modules
  • Regular Expressions
  • Highlights of the Standard Library
  • Introduction to Python Classes
  • Real-life programming
  • Special data types
  • Network services
  • Dates and times

Course Objectives:

Throughout the course students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review. This course is “skills-centric”, designed to train attendees in core Python and web development skills beyond an intermediate level, coupling the most current, effective techniques with best practices.

Working within in an engaging, hands-on learning environment, guided by our expert Python practitioner, students will learn to:

  • Create working Python scripts following best practices
  • Use python data types appropriately
  • Read and write files with both text and binary data
  • Search and replace text with regular expressions
  • Get familiar with the standard library and its work-saving modules
  • Use lesser-known but powerful Python data types
  • Create “real-world”, professional Python applications
  • Work with dates, times, and calendars
  • Know when to use collections such as lists, dictionaries, and sets
  • Understand Pythonic features such as comprehensions and iterators
  • Write robust code using exception handling

Skills-Focused, Hands On Learning: This course is about 50% hands-on lab to 50% lecture ratio, combining engaging instructor presentation, demos and practical group discussions with lab intensive, machine-based student exercises. Throughout the course students will learn to write essential Python scripts using the latest technical skills and best practices. Our Python courses include a wide range of complementary materials and labs to ensure all students are appropriately challenged – no matter their incoming skill level.
