#Python find file in directory with pattern code

The glob method is much faster and the code for it is shorter. > oswalk_files = get_filepaths_with_oswalk(root_path,'filename_(.*).csv') On using the above two functions to find 5076 files matching the regex filename_*.csv in a dir called root_path (containing 66,948 files): > glob_files = get_filepaths_with_glob(root_path, 'filename_*.csv') Return glob.glob(os.path.join(root_path, file_regex))Ĭomparing runtimes of the above functions Your code lacks a if name 'main': starting section. glob Unix style pathname pattern expansion Python 3.11.4 documentation Basic usage of glob() Wildcards available in glob(). If you're going to write python, PEP8 states snakecase should be used as the expected style. In Python, the glob module allows you to get a list or an iterator of file and directory paths that satisfy certain conditions using special characters like the wildcard. It is also predicted that according to benchmarks it is faster than other methods to match pathnames in directories. Return get_filepaths_with_glob(root_path: str, file_regex: str): Firstly some tips: Your code uses a mixture of snakecase and camelCase, you should stick to a specific style. The pattern rules of glob follow standard Unix path expansion rules. Return get_filepaths_with_oswalk(root_path: str, file_regex: str):įor root, directories, files in os.walk(root_path):įiles_paths.append(os.path.join(root, file)) The snippet also contains a 'stopwatch' function to time the two functions. Snippet import os for (root, dirs, file) in os. You can iterate the files list and access the files in the directory. It’ll return two separate lists of files and folders. The below snippet contains two file-regex searching functions (one using glob and the other using a custom file-walking-regex matcher). To display only the files in a directory, you can use the os.walk () method.

Snippets of functions using glob and a file-walking-regex matcher

Given that you are a beginner, I would recommend using glob in place of a quickly written file-walking-regex matcher.
