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, path
import subprocess

if __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 fnmatch
from os import walk, path, remove
import sys

if 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]])

    计算身份证最后一位校验码
    '''
    id_card_str = '42028118921027721'
    x = [1, 0, 'X', 9, 8, 7, 6, 5, 4, 3, 2]
    coefficient = np.array([7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2])

    id_card = np.array(list(id_card_str), dtype=int)
    x_id = id_card.dot(coefficient) % 11
    id_card_str += str(x[x_id])
    print(id_card_str)
