Python puts the files in the folder into different folders according to the extension

Purpose: There are many files in a folder, and there are many kinds of extensions, it is very troublesome to copy and paste manually, I want to use code to achieve.
Create a new folder with some files for testing: The
code implements a new folder based on the extension, and puts all files with the same extension under this folder:

import shutil
import os
def classify(filespath,outpath):
    files=os.listdir(filespath)  # 获取所有的文件
    for x in files:
        srcname=os.path.join(filespath,x)  #每个文件的完整路径
        houzhui=x.split(".")[-1]  # 获取后缀名
        outfiles=os.path.join(outpath,houzhui) # 要放入的文件夹的路径
        if not os.path.exists(outfiles): # 路径不存在则创建
            os.mkdir(outfiles)
        filename=outfiles+"\\"+x
        print("复制文件---{}到--{}".format(srcname,filename))
        shutil.copyfile(srcname,filename)  # 复制文件


if __name__=='__main__':
    filespath = "E:/program/python/test"  # 存放文件的文件夹路径
    outpath = "E:/program/python/ffoutput" # 分类后的文件夹路径
    classify(filespath,outpath)

The code is mainly the shutil.copyfile(src,dst) module:

def copyfile(src, dst, *, follow_symlinks=True):
    """Copy data from src to dst.

    If follow_symlinks is not set and src is a symbolic link, a new
    symlink will be created instead of copying the file it points to.

    """

src and dst must be files, not directories. If dst already exists, it will be overwritten.
