写copy函数

import os
def copy(path1, path2):
    filename = os.path.basename(path1)
    if os.path.isdir(path2) and os.path.isfile(path1):
        path2 = os.path.join(path2, filename)
        if os.path.exists(path2):
            print("已有同名文件！")
        with open(path1, "rb") as f1, \
                open(path2, "wb") as f2:
            content = f1.read()
            f2.write(content)
copy(r‘G:\salar\day17\random模块.py‘, r‘G:\salar\day15‘)
