getFolder.py

import os
def getFolder(path):
    folders = []
    all = os.listdir(path)
    for some in all:
        get = os.path.join(path, some)
        if os.path.isdir(get):
            folders.append(get)
    return folders
# print(getFolder("./")) #debug

getFiles.py

import os

def getFiles(path):
    files = []
    all = os.listdir(path)
    for some in all:
        get = os.path.join(path, some)
        if os.path.isdir(get) == False:
            files.append(get)
    return files
# print(getFiles("./")) #debug

pngtopdf.py

from PIL import Image
from breakpointResumption import  goahead

    if goahead(output):
        pngs = []
        for file in inputs:

            pngs.append(img)
        pngs[0].save(output, save_all=True, append_images=pngs[1:], quality=95)
        print(f"{output}已完成")

breakpointResumption.py

import os

    if os.path.exists(path):
        return False
    else:
