  • 批量处理文件的Python程序

    经常批量处理文件,这里有个python的模板,保存一下

    这个例子是把目录里面所有子目录的mp3文件放慢0.85倍并保存到./processed/目录下面。

    #coding=utf-8
    import sys,os ,shutil
    import struct
    import glob
    import time
    import subprocess
    
    
    def slow(file_name,to_file):
        command='ffmpeg -i {} -af atempo=0.85 {} '.format(file_name,to_file)
        print(command)
        os.system(command)
    
    def process_file(file_name,dest_node):
        if not file_name.endswith('.mp3'):
            return;
        slow(file_name,dest_node)
    
    def process_dir(folder):
        for sub_node in glob.glob ( folder+'/*' ):
            dest_node=sub_node.replace(node,"../processed/")
            if os.path.isdir(sub_node):
                if not os.path.isdir(dest_node):
                    os.mkdir(dest_node)
                process_dir(sub_node)
            else:
                process_file(sub_node,dest_node)
    
    node=sys.argv[1]
    if os.path.isdir(node):
        process_dir(node)
        for pcm_file in glob.glob ( node+'/*' ):
            process_file(pcm_file)
    if os.path.isfile(node):
        with open(node, 'r') as file_to_read:
            for line in file_to_read.readlines():
                process_file(line)
