This example demonstrates how to gather full file paths for files in a directory that match user-defined criteria. It defines a `filter_files_in_dir` function that takes a base directory, an optional custom filter function, and an optional file extension. Using Python’s `os.listdir` and `itertools.filterfalse`, it iterates over directory entries, applying the filter and a suffix check via `str.endswith`. Matching filenames are joined with the directory using `os.path.join` and returned as a list. The code shows a reusable pattern for filtering file collections without external dependencies.

subdirectory files

This example demonstrates how to recursively traverse a directory structure using Python’s `os.walk` API to collect all file paths into a set, then prints the count and the set of relative paths. The visualization shows the logical hierarchy of files and folders, with the code relying on `os.path.relpath` to generate clean, relative file locations from the root directory. The rendering approach is text-based output rather than a graphical chart, emphasizing the data collection and enumeration process. The script’s behavior is limited to listing files, with no sorting, filtering, or graphical mapping applied.

[对生成器进行过滤] 生成器由于无法事先知道长度，因此无法直接使用切片操作，但是可以使用 itertools.islice() 来自动遍历；也可以使用 dropwhile 来过滤开头一部分元素 #python

This example demonstrates two techniques for working with Python generators when standard slicing and filtering are not directly available. It shows how `itertools.islice()` can apply slice-like operations to a generator by traversing it, converting the result to a list to extract values. It also illustrates `itertools.dropwhile()` to skip leading lines from a file that start with `#`, reading from `/etc/passwd` until the first non-comment line. Both approaches highlight the use of iterator utilities to handle streams without knowing their length beforehand.

[创建临时文件和文件夹] #python

This example demonstrates four Python recipes for creating temporary files and directories using the `tempfile` module. It shows anonymous temporary files via `TemporaryFile`, named temporary files with `NamedTemporaryFile` and its configurable `prefix`, `suffix`, and `dir` parameters, and temporary directories through `TemporaryDirectory`. The code also queries the system’s temporary file location with `gettempdir()`. Each use case is illustrated with a `with` block, emphasizing automatic cleanup, and the example writes and reads text to confirm functionality.

Renaming files in many sub-folders. Requirement: There is a huge directory list which has many sub-directories and one file in each sub-directory, which has to be renamed as sub-directory name with the original extension. Last sub-directory name is always 8 chars. After renaming is done, it has to be moved to a different folder. Wrote a small Python utility for this requirement.

This example demonstrates a Python utility that renames a single file inside each sub-directory to match the sub-directory name while preserving the original extension, then moves it to a destination folder. It shows how `os.walk` traverses the directory tree, identifies the last 8 characters of each sub-directory name via string slicing, and uses `os.rename` to relocate and rename the file to `D:/GBR/`. The code relies on the standard `os` library for file system operations.

search and read

This example demonstrates a file-searching utility that locates every `target.txt` file within a directory tree and prints its contents to the console. The code uses the `os.walk` API to traverse directories recursively, collecting paths where the target file exists, then opens and reads each matching file with Python’s built-in `open` function. The rendering approach is purely text-based, with output delivered as sequential lines from each located file. No external visualization libraries are employed; instead, the focus is on demonstrating filesystem traversal and conditional file matching through standard library functions.

[遍历直到遇到特定值]不断遍历，直到遇到一个特定值为止 #python

This example demonstrates how to iterate over data until a specific sentinel value is encountered, using Python’s built-in `iter` function with a callable and a sentinel argument. It shows reading a text file in fixed-size chunks—10 characters at a time—via `f.read(10)` inside a lambda, stopping when an empty chunk is returned. The visualization highlights the mechanism of `iter` with a sentinel: the first parameter must be callable when a sentinel is present, unlike the standard iterable-only form. This pattern is useful for terminating loops based on data content rather than a fixed count.

Gist 133cb61af931a08bbe20

This example demonstrates recursive directory traversal as a streaming pipeline in Haskell, yielding each file path as a producer. The code uses the `Pipes` library, with `getRecursiveContents` recursively descending into subdirectories via `getDirectoryContents` and filtering out `.` and `..`. Each file path is then piped through `P.map` to prefix `"Found file "` and sent to `P.stdoutLn` for output. The main function takes a starting path from command-line arguments via `getArgs`, illustrating a functional, lazy approach to filesystem enumeration.

Filter api example

This example demonstrates the process of requesting a filtered dataset from the UK Office for National Statistics (ONS) API and asynchronously retrieving the resulting CSV file. It uses Python with the `requests` library to POST a JSON payload specifying a dataset edition and a geography dimension filter, then polls the returned `filter_output` link until the data is ready. The code parses the JSON response with `json.loads` and reads the CSV into a pandas DataFrame using `pd.read_csv`, highlighting an API workflow for on-demand data extraction.
