import osdef 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')
