python实现拷贝指定图片到另一个路径

import os
import shutil

dir = os.getcwd()
print(dir)
filename = "path.txt"
path = os.path.join(dir,filename)
print(path)
f2 = open(path,'r')
for item in f2:
    res = item.split("=")
    if res[0] == "src":
        src = res[1]
        print(src)
    if res[0] == "dst":
        dst = res[1]
        print(dst)


mydir =src[:-1]
dstdir = dst[:-1]
if not os.path.exists(dstdir):
    os.makedirs(dstdir)

files = os.listdir(mydir)
for file in files:
    filepath = os.path.join(mydir,file)
    if os.path.isdir(filepath):
        jpgs = os.listdir(filepath)
        for jpg in jpgs:
            if "a_left" in jpg or "a_right" in jpg:
                dstpath = os.path.join(dstdir, file)
                if not os.path.exists(dstpath):
                    os.makedirs(dstpath)
                jpgpath= os.path.join(filepath,jpg)
                print(jpgpath)
                jpgdst = os.path.join(dstpath,jpg)
                print(jpgdst)
                shutil.copy(jpgpath, jpgdst)
