File Systems and File Processingng and closing files, for both reading and writing, using Python. Lastly, we describe iterating through the lines of a file (both textual and comma-separated value) to extract data, and JSON file processing tools.

Python Native Data Structures two-dimensional data. We discuss the pros and cons of each representation, and common patterns for creating them, filtering and mutating them, and extracting data from them. This discussion includes list comprehensions, accumulation, lambda functions, and mapping functions onto lists and dictionari

Regular Expressionsing, wildcard characters, matching a particular number of repetitions, disjunction, capture groups, and the use of anchors to control where a match occurs. We illustrate each concept with a Python example and describe applications where regular expressions are commonly used.

Data Systems Modelsh model: via its structure, operations, and constraints. For each of the three models, we give a high-level summary of its design, common operations (e.g., to access, mutate, or aggregate data), and rules that data in the model must satisfy.

Tabular Model: Structure and Formatsriables to dependent variables, and file formats. We introduce the “pandas” module and the concept of a “DataFrame.” We illustrate how to read data from a comma-separated value file using Python programming, and using “pandas.” Lastly, we introduce basic “pandas” methods that operate on an entire “D

Relational Model: Database Programmingdatabase, be it in a local SQLite file, or over a network interacting with a DBMS such as MySQL. Topics include establishing connections with the database, issuing SQL queries and retrieving results, and incorporating local variables in the construction of queries. The programming also ties back to
