從資料夾裡面找到最新的檔案

import os
def newest(path, suffix=None):
    """
    suffix: suffix for specific file, or default to find newest file but don't care about suffix.
    """
    if suffix:
        files = [i for i in os.listdir(path) if i.__contains__(suffix)]
    else:
        files = os.listdir(path)
    paths = [os.path.join(path, basename) for basename in files]
    return max(paths, key=os.path.getctime)
