关于python的文件清理操作,实际上我们使用标准模块os即可满足所有的文件操作。

一般在C盘的清理过程中,我们能够清理的文件类型主要如下:

'''
'.tmp': '临时文件',
    '._mp': '临时文件_mp',
    '.log': '日志文件',
    '.gid': '临时帮助文件',
    '.chk': '磁盘检查文件',
    '.old': '临时备份文件',
    '.xlk': 'Excel备份文件',
    '.bak': '临时备份文件bak'
'''
Copy after login

既然已经知道了需要清理的文件类型,那实现思路就是将这些文件找出来后删除掉即可。

将我们接下来代码块中使用到的os标准模块直接导入到代码块中。

# Importing the os module.
import os
Copy after login

现在可以将一些全局变量首先定义好,比如全局的系统操作路径、待清理的文件后缀名等等。

# 待清理的文件后缀名称
suffix_dict = {
    '.tmp': '临时文件',
    '._mp': '临时文件_mp',
    '.log': '日志文件',
    '.gid': '临时帮助文件',
    '.chk': '磁盘检查文件',
    '.old': '临时备份文件',
    '.xlk': 'Excel备份文件',
    '.bak': '临时备份文件bak'
}

# 用户缓存数据类型名称
user_profile_list = [
    'cookies', 'recent', 'Temporary Internet Files', 'Temp'
]

# windows系统路径文件类型
windir_list = [
    'prefetch', 'temp'
]

# 系统驱动路径
sys_drive = os.environ['systemdrive'] + '\\'

# 用户缓存路径
user_profile = os.environ['userprofile']

# windows系统路径
win_dir = os.environ['windir']
Copy after login

以上相关的C盘清理的全局变量已经设置完成了,接下来我们创建一个ClaenFilesUtil的类来完成对文件清理的业务操作过程。

# This class is used to clean up files in a directory
class CleanFilesUtil():
    def __init__(self):
        """
        A constructor. It is called when an object is created from a class and it allows the class to initialize the
        attributes of a class.
        """
        self.del_info = {}
        self.del_file_paths = []
        self.total_size = 0
        for suffix_name, comment in suffix_dict.items():
            self.del_info[suffix_name] = dict(name=comment, count=0)

    def scanf_files(self):
        """
        It takes a list of files, and returns a list of lists of the lines in each file
        """
        for roots, dirs, files in os.walk(user_profile):
            for files_item in files:
                file_extension = os.path.splitext(files_item)[1]
                if file_extension in self.del_info:
                    file_full_path = os.path.join(roots, files_item)
                    self.del_file_paths.append(file_full_path)
                    self.del_info[file_extension]['count'] += 1
                    self.total_size += os.path.getsize(file_full_path)

    def show_count_message(self):
        """
        It prints the number of messages in the inbox.
        """
        byte = self.format_size(self.total_size)
        for i in self.del_info:
            print(self.del_info[i]["name"], "共计", self.del_info[i]["count"], "个")
        return byte

    def format_size(self, byte):
        """
        It takes a number of bytes and returns a string with the number of bytes, kilobytes, megabytes, or gigabytes,
        depending on the size

        :param byte: The size in bytes
        """
        try:
            kb = byte // 1024
        except:
            print("传入字节格式不对")
            return "Error"
        if kb > 1024:
            M = kb // 1024
            if M > 1024:
                G = M // 1024
                return "%dG" % G
            else:
                return "%dM" % M
        else:
            return "%dkb" % kb

    def remove_file_or_dir(self):
        """
        > This function removes a file or directory
        """
        for full_path_one in self.del_file_paths:
            try:
                if os.path.isfile(full_path_one):
                    os.remove(full_path_one)
                    print("文件:", full_path_one, "已移除")
                elif os.path.isdir(full_path_one):
                    os.rmdir(full_path_one)
                    print("文件夹", full_path_one, "已移除")

            except WindowsError:
                print("错误:", full_path_one, "不能被移除")


if __name__ == "__main__":
    print("开始初始化C盘清理程序")
    clean_ = CleanFilesUtil()
    print('C盘清理程序初始化完成')
    print("开始扫描所有待清理文件路径")
    clean_.scanf_files()
    print("完成所有待清理文件路径扫描")
    print("扫描完成以下是需要待清理的文件路径:")
    clean_.show_count_message()
    print("开始执行C盘垃圾文件删除")
    clean_.remove_file_or_dir()
    print("所有C盘垃圾文件已清理完成")
    input("输入任意键关闭窗口...")
Copy after login

于是,我想到了前几天发布的文章[python不要再使用while死循环,使用定时器代替效果更佳!],可以通过定时器的方式来满足业务要求。

除了使用代码块来完成定时还可以通过配置windows或其他操作系统的定时任务来完成定时执行的需求。
