python实现文件复制

利用windows copy命令实现将一个文件夹中的文件拷贝到还有一个文件夹

from os import listdir, pathimport subprocessif __name__ == "__main__":    INPUT_DIR = r'E:\Entertain\Videos'    OUTPUT_DIR = r'C:\Users\pi\Desktop\out'    all_output_dir_filenames = listdir(OUTPUT_DIR)    all_output_dir_filenames.append('desktop.ini')    for file_name in listdir(INPUT_DIR):        if file_name not in all_output_dir_filenames:            filename = path.join(INPUT_DIR, file_name)            # print(filename)            subprocess.Popen(["copy", filename, OUTPUT_DIR], shell=True)

python遍历和删除指定文件夹下全部的pyc文件

E:\mine\python_workspace\Utility\DelPyc.py:

#!/usr/bin/env python# -*- coding: utf-8 -*-"""__title__ = ''__author__ = 'pi'__mtime__ = '7/29/2015-029'"""import fnmatchfrom os import walk, path, removeimport sysif len(sys.argv) >= 3:    EXT = sys.argv[2]    DEL_DIR = sys.argv[1]elif len(sys.argv) >= 2:    EXT = 'pyc'    DEL_DIR = sys.argv[1]else:    EXT = 'pyc'    DEL_DIR = r'E:\mine\python_workspace\WebSite'if not path.exists(DEL_DIR):    print('error: DEL_DIR not found!!!')    exit()print('DEL_DIR: ', DEL_DIR, '\ndelete file extension: ', EXT)print('deleted files:\n')def del_pyc(DEL_DIR):    for filepath, _, filename_list in walk(DEL_DIR):        for filename in filename_list:            if fnmatch.fnmatch(filename, '*.' + EXT):  # unix shell风格匹配方式                # if filename.endswith('.pyc'):                print(filename)                remove(path.join(filepath, filename))if __name__ == '__main__':    del_pyc(DEL_DIR)

Note:上面的程序是针对当前pycharm中打开的py文件相应的文件夹删除当中全部的pyc文件。假设是直接执行（而不是在以下的tools中执行）。则删除E:\mine\python_workspace\WebSite文件夹下的pyc文件。

python代码出错重新启动

执行python代码某个片断出错。能够重新启动本代码继续执行

try:    ...except:    time.sleep(2)    subprocess.call(['python', sys.argv[0]])
