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.

4.1 Single, double, and triple quotes

You may use single quotes or double quotes to delimit a literal string. Python usually prints a string with single quotes.


If your string contains one kind of quote, use the other as the delimiter or escape the quote mark.

"That is Franz's cat toy."
"That is Franz's cat toy."
'The ball is Ferdinand\'s.'
"The ball is Ferdinand's."

Use the character '\n' character to embed a newline in your string.

"You can see the\nnewline character here."
'You can see the\nnewline character here.'
print("But 'print' breaks\nthe line at the character.")
But 'print' breaks
the line at the character.

For very long strings, you can concatenate them together...
