You’ll learn about built-in modules from the standard library and popular third-party packages that enhance Python’s capabilities for both basic and advanced programming tasks. Protip: Use pip list or pip freeze to list all installed Python packages and modules. For tree-like visualization, fir...

In addition to alternative list implementations, the library also offers other tools such as the bisect module with functions for manipulating sorted lists:>>> >>> import bisect >>> scores = [(100, 'perl'), (200, 'tcl'), (400, 'lua'), (500, 'python')] >>> bisect.insort(scores...

The copytree() function alleviates a particularly irritating behavior of the standard library’s shutil.copytree() function: Boltons’ copytree() will not complain if some or all of the destination file-system tree already exists.The boltons.fileutils.AtomicSaver context manager helps to make sure...
