## 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复制到另一个文件夹

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遍历和删除指定目录下所有的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文件对应的目录删除其中所有的pyc文件。如果是直接运行（而不是在下面的tools中运行），则删除E:\\mine\\python\_workspace\\WebSite目录下的pyc文件。[

## python代码出错重启 ##

执行python代码某个片断出错，可以重启本代码继续执行

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

其它方法\[[python实现自动重启本程序的方法][python]\]

## 计算身份证最后一位校验码 ##

def identifier():
        '''
        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)
