8 7 sequences and series an introduction to python jupyter notebooks

Below is the list of topics that are covered in this section: In this module, we define a sequence as an arrangement of an infinite number of numbers written in a specific order. The common notations used for a sequence are \(\left\lbrace a_n\right\rbrace = \left\lbrace a_n\right\rbrace_{n=1}^{\infty} = \left\lbrace a_1, a_2, \ldots \right\rbrace\), where \(a_i\) denote the \(i^{\text{th}}\) term of the sequence. Write the first 5 terms of the following sequences: \(\left\lbrace \dfrac{1}{n} \right\rbrace = \dfrac{1}{1}, \dfrac{1}{2}, \dfrac{1}{3}, \dfrac{1}{4}, \dfrac{1}{5}, \ldots\) Sequences and series are fundamental concepts in mathematics.

A Sequence is an ordered list of numbers following a specific pattern, while a series is the sum of the elements of a sequence. This tutorial will cover arithmetic sequences, geometric sequences, and how to work with them in Python. An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant. This difference is called the common difference (d). Sum of the first n terms: Sn​ = (n/2)​ * (2 * a1​ + (n−1) * d) A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous term by a constant called the common ratio (r).

Sum of the first n terms (if r != 1): Sn​ = (a1/(​1−r^n))/(1−r)​ There was an error while loading. Please reload this page. Summary: in this tutorial, you’ll learn about the Python sequences and their basic operations. A sequence is a positionally ordered collection of items. And you can refer to any item in the sequence by using its index number e.g., s[0] and s[1].

In Python, the sequence index starts at 0, not 1. So the first element is s[0] and the second element is s[1]. If the sequence s has n items, the last item is s[n-1]. Python has the following built-in sequence types: lists, bytearrays, strings, tuples, range, and bytes. Python classifies sequence types as mutable and immutable. The mutable sequence types are lists and bytearrays while the immutable sequence types are strings, tuples, range, and bytes.

When I wrote the first edition of this book in 2011 and 2012, there were fewer resources available for learning about doing data analysis in Python. This was partially a chicken-and-egg problem; many libraries that we now take for granted, like pandas, scikit-learn, and statsmodels, were comparatively immature back then. Now in 2022, there is now a growing literature on data science, data analysis, and machine learning, supplementing the prior works on general-purpose scientific computing geared toward computational scientists, physicists, and professionals in other... There are also excellent books about learning the Python programming language itself and becoming an effective software engineer. As this book is intended as an introductory text in working with data in Python, I feel it is valuable to have a self-contained overview of some of the most important features of Python’s... So, I will only present roughly enough information in this chapter and Ch 3: Built-in Data Structures, Functions, and Files to enable you to follow along with the rest of the book.

Much of this book focuses on table-based analytics and data preparation tools for working with datasets that are small enough to fit on your personal computer. To use these tools you must sometimes do some wrangling to arrange messy data into a more nicely tabular (or structured) form. Fortunately, Python is an ideal language for doing this. The greater your facility with the Python language and its built-in data types, the easier it will be for you to prepare new datasets for analysis. Python is a widely used, high-level programming language known for its simplicity, readability, and versatility. One of the key aspects in Python programming is the concept of series, which is essential for handling sequences of data.

Whether you are a beginner taking your first steps in programming or an experienced developer looking to refresh your knowledge, this blog post will provide you with in-depth insights into Python series, their usage,... In Python, a sequence is an ordered collection of elements. Sequences are one of the fundamental data structures in the language. They provide a way to store and organize related data items. The elements in a sequence can be of different data types, such as integers, strings, or even other sequences. Slicing allows you to extract a portion of a sequence.

The syntax is sequence[start:stop:step]. - Lists: The generator uses less memory as it generates values on-the-fly instead of storing all values in memory. Python series, including lists, tuples, and strings, are essential data structures in Python programming. Understanding their fundamental concepts, usage methods, common practices, and best practices is crucial for writing efficient and reliable Python code. Whether you are building a simple script or a complex application, these concepts will serve as the foundation for your Python development journey.

You have already used the IPython shell to run the code line by line. This is good, but if you have a more lines of codes and want to run it block by block and share it easily with others, the Ipython shell is not a good option. In this section, we will introduce another option - Jupyter notebook, that we will use for the rest of the book. From the Jupyter notebook website: The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more.
