python之拷贝文件

使用python实现类似cp的功能

方式一： 文件with读写模式

#!/bin/python3
# -*- coding: utf-8 -*-
src_file=input('源文件路径：').strip()
dst_file=input('目标文件路径：').strip()
with open (r'%s' %src_file,mode='rb') as read_f,\
    open (r'%s' %dst_file,mode='wb') as write_f:
        for line in read_f:
            write_f.write(line)

# python3 4.py
源文件路径：1
目标文件路径：1.html
# ls 1.html
1.html

方式二： 使用sys模块实现

# cat 3.py
#!/bin/python3
# -*- coding: utf-8 -*-
import sys
src_file=sys.argv[1]
dst_file=sys.argv[2]
with open (r'%s' %src_file,mode='rb') as read_f,\
    open (r'%s' %dst_file,mode='wb') as write_f:
        for line in read_f:
                write_f.write(line)

# python3 3.py py.py  4.py
#cat 4.py
#!/bin/python3
# -*- coding: utf-8 -*-
@version: 3.0
