How to loop through a folder containing a large number of files using Python?
Article Introduction:When processing training data for large models, it is often necessary to traverse large folders, which may include tens or hundreds of millions of files. At this time, general Python traversal functions will be very slow, such as os.walk, glob, path .rglob, etc. At the same time, the overall traversal time cannot be estimated. This article uses Python's os.scandir and based on the breadth-first search algorithm to achieve controllable and efficient traversal of files. At the same time, it outputs traversal logs, supports suffix filtering, removes hidden files, and realizes the function of traversing folders containing a large number of files. os.scandir is a directory iteration function that returns an iterator of os.DirEntry objects corresponding to the directories in the directory specified by path.

PHP glob() function usage example: traverse all files in a specified folder
Article Introduction:Example of using PHPglob() function: Traverse all files in a specified folder In PHP development, it is often necessary to traverse all files in a specified folder to implement batch operation or reading of files. PHP's glob() function is used to achieve this requirement. The glob() function can obtain the path information of all files that meet the conditions in the specified folder by specifying a wildcard matching pattern. In this article, we will demonstrate how to use the glob() function to iterate through all files in a specified folder
