Good software is tested software. Testing our code can help us catch bugs or unwanted behavior.
Test Driven Development (TDD) is a software development practice that requires us to incrementally write tests for features we want to add. It leverages automated testing suites, like pytest - a testing framework
As serialized data structures, Python programmers intensively use arrays, lists, and dictionaries. Storing these data structures persistently requires either a file or a database to work with. This article describes how to write a list to file, and how to read that list back into memory.
To work with stored data, file handling belongs to the core knowledge of every professional Python programmer. Right from its earliest release, both reading and writing data to files are built-in Python features. In comparison to other programming languages like C or Java it is pretty simple and only requires
When it comes to using Python to copy files, there are two main ways: using the shutil module or the os module. All of the os methods we show here are methods that allow us to execute shell commands from our Python code, which we'll use to execute the
Computer programs are written with a specific purpose in mind. Tools on UNIX/Linux systems follow the idea of specialization - one tool for one task, but to do it as perfect as possible, then. Nethertheless, as with other tools, this allows you to combine single programs, and to
