python_sys.argv的使用

# sys.argv练习

# 写一个python脚本,在cmd里执行

# python xxx.py 用户名 密码 cp 文件路径 目的地址

# python xxx.py alex sb cp D:\python_22\day22\1.内容回顾.py D:\python_22\day21

# python xxx.py alex sb rm D:\python_22\day22

# python xxx.py alex sb rename D:\python_22\day22  D:\python_22\day23

import os

import sys

import shutil

if len(sys.argv) >= 5:

    if sys.argv[1] =='alex' and sys.argv[2] == 'sb':

        if sys.argv[3] == 'cp' and len(sys.argv) == 6:

            if os.path.exists(sys.argv[4]) and os.path.exists(sys.argv[5]):

                filename = os.path.basename(sys.argv[4])

                path = os.path.join(sys.argv[5],filename)

                shutil.copy2(sys.argv[4],path)

        elif sys.argv[3] == 'rm' and len(sys.argv) == 5:

            if os.path.exists(sys.argv[4]):

                if os.path.isfile(sys.argv[4]):

                    os.remove(sys.argv[4])

                else:

                    shutil.rmtree(sys.argv[4])

        elif sys.argv[3] == 'rename'and len(sys.argv) == 6:

            if os.path.exists(sys.argv[4]):

                    os.rename(sys.argv[4],sys.argv[5])

else:

    print('您输入的命令无效')

将脚本改写成下面的样子：

import os

import sys

import getopt

import shutil

class Fileoperation(object):

    def __init__(self,username,psw,func_name,path1='',path2=''):

        self.username=username

        self.psw=psw

        self.func_name=func_name

        self.path1=path1

        self.path2=path2

    def cp(self):

        if os.path.exists(self.path1) and os.path.exists(self.path2):

            filename = os.path.basename(self.path1)

            target_path = os.path.join(self.path2,filename)

            shutil.copy2(self.path1,target_path)

        else:

            print('path1或path2不存在')

    def rm(self):

        if os.path.exists(self.path1):

            if os.path.isfile(self.path1):

                os.remove(self.path1)

            else:

                shutil.rmtree(self.path1)

        else:

            print('path1目录不存在')

    def rename(self):

        if os.path.exists(self.path1):

            os.rename(self.path1,self.path2)

    def main(self):

        if self.func_name == "cp":

            Fileoperation.cp(self)

        elif self.func_name == "rm":

            Fileoperation.rm(self)

        elif self.func_name == "rename":

            Fileoperation.rename(self)

        else:

            print('func_name有误')

if __name__ == '__main__':

    username=''

    psw=''

    func_name =''

    path1=''

    path2=''

    argv = sys.argv[1:]

    try:

        opts, args = getopt.getopt(argv, "h", ["username=","psw=","func_name=", "path1=", "path2="])

    except getopt.GetoptError:

        print('有错误发生','collin_file_operation.py --username username --psw psw --path1 source path --path2 target path')

        sys.exit(2)

    for opt, arg in opts:

        if opt == "-h":  # 提示，帮助功能

            print('collin_file_operation.py --username username --psw psw --path1 source path --path2 target path')

            sys.exit()

        elif opt == "--username":

            username = arg

        elif opt == "--psw":

            psw = arg

        elif opt == "--func_name":

            func_name = arg

        elif opt == "--path1":

            path1 = arg

        elif opt == "--path2":

            path2 = arg

    # print(process_name + "--"+log_path+"--"+excel_path+"--"+new_excel_path+"")

    handle = Fileoperation(username,psw,func_name,path1,path2)

    handle.main()

cmd 执行的命令：

复制文件：

C:\Users\12078\PycharmProjects\OldBoy\Day22>

python collin_file_operation.py --username=alex --psw=123 --func_name=cp --path1=C:\Users\12078\PycharmProjects\OldBoy\Day22\test\targethaha.py --path2=C:\Users\12078\PycharmProjects\OldBoy\Day22\test2

移除文件：

C:\Users\12078\PycharmProjects\OldBoy\Day22>

python collin_file_operation.py --username=alex --psw=123 --func_name=rm --path1=C:\Users\12078\PycharmProjects\OldBoy\Day22\test\targethaha.py

重命名文件：

C:\Users\12078\PycharmProjects\OldBoy\Day22>

python collin_file_operation.py --username=alex --psw=123 --func_name=rename --path1=C:\Users\12078\PycharmProjects\OldBoy\Day22\test2\targethaha.py --path2=C:\Users\12078\PycharmProjects\OldBoy\Day22\test2\target_hihi.py
