Dancing with Python

By: Robert S. Sutor

Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

8.4 Lists of files and folders

If I have the five file names,,,, and,

then I can use wildcard characters to match some of the names. Here are some examples:

  • The pattern “*.py” matches all of them since the pattern means “the name may start with any characters but must end in “.py’.”
  • The pattern “*01*” matches and
  • unipoly_0?.py” matches and The “?” is a single character wildcard and matches anything in that one position.

Using patterns like these to match file names is called “globbing” and goes back to the early days of UNIX in the late 1960s and early 1970s. The glob module implements globbing in Python.
