Online course Part-time course
Diploma in Python Programming

This Diploma in Python Programming course is targeted towards those with little or no experience in programming who are looking to begin their career in programming or advance their career with the Python programming language. Python is a general-purpose programming language that has a wide range of industry applications, from small single task scripts to complete desktop applications.

Python is a programming language which has recently begun to gain an ever-increasing market share. The cross-platform nature of Python allows it to be used for different tasks on any operating system. This allows Python developers to be utilised for many different IT related roles.

This course leads the students 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. Particular emphasis is placed on features unique to Python, such as tuples, array slices, and output formatting. Students should be comfortable using the basic operating system on their laptop (Linux, Unix, Windows, Solaris or Mac OS X, etc.) on which they will be running Python. While not mandatory, basic skills with at least one other programming language are desirable. Students receive a copy course notes and will be able to see the instructor’s screen simultaneously with working on their own.

CCT College Dublin Professional Certification confirms the successful completion of the Diploma in Python Programming. Professional Certification supports career advancement through verification of upskilling. This programme does not lead to an award on the National Framework of Qualifications (NFQ).

On completion of this course, the learner will have acquired the skills to:

  • Master the fundamentals of writing Python scripts
  • Learn core Python scripting elements such as variables and flow control structures
  • Discover how to work with lists and sequence data
  • Write Python functions to facilitate code reuse
  • Use Python to read and write filesMake their code robust by handling errors and exceptions properly
  • Work with the Python standard library
  • Explore Python’s object-oriented features
  • Search text using regular expressions

This section provides a detailed breakdown of all of the content covered during this course.
