How to list files under the specified directory in a list (multiple conditions / subdirectory search)

Assume the directory where the files are located as shown below.

c:\pics\
	a.png
	b.jpg
	subfolder\
		c.png
		d.jpg

code

I made a function like this. "Exts" is a file extension, but I think it will work even if you specify conditions other than the extension.


from pathlib import Path


def file_search(file_path, exts, search_subfolder):
    """
    # file_path:Directory to search
    # exts:File extension(Example:['*.jpg', '*.png']
    """
    files = []
    p = Path(file_path)
    for ext in exts:
        if search_subfolder:
            files.extend(list(p.glob('**\\'+ext)))
        else:
            files.extend(list(p.glob(ext)))
    return files

I will call it from main like this.


def main():
    file_path = r'C:\pics' + '\\'
    exts = ['*.jpg', '*.png']

    files = file_search(file_path, exts, True)
    pprint(files)

Execution result

py searchpic.py

[WindowsPath('C:/pics/b.jpg'),
 WindowsPath('C:/pics/subfolder/d.jpg'),
 WindowsPath('C:/pics/a.png'),
 WindowsPath('C:/pics/subfolder/c.png')]

That's why I was able to search for files with multiple extensions under the subfolder. In this case, the contents of the returned files are WindowsPath, not a string. For files, if strings are more convenient


files_str = list(map(lambda x: str(x), files))

You can make a list of character strings by converting it like this.
