Just two clicks and you can convert a bunch of JPGs into a single PDF, with the PDF file named after the folder where the JPGs are located.
現在遇到一個問題，這個問題是要將一堆的JPG轉成一個PDF，並且這個PDF的檔名為一堆JPG所在的資料夾名稱。
I am currently facing an issue where I need to convert a bunch of JPGs into a single PDF, and the PDF file should be named after the folder where the JPGs are located.
在資料來源1.Convert Images to PDF using Python，發現程式碼如下：
In data source 1, "Convert Images to PDF using Python," I found the following code:
from PIL import Image
image_1 = Image.open(r'path where the image is stored\file name.png')
im_1 = image_1.convert('RGB')
im_1.save(r'path where the pdf will be stored\new file name.pdf')
所以我需要安裝套件 Pillow、jpg檔案位置。
So I need to install the Pillow package and provide the location of the JPG files.
Here is the website where you can download the program and find instructions:

以下是開發過程與原始碼 (Development process and code)：
安裝Pillow套件(Install the Pillow suite)
安裝套件指令(command)：pip install Pillow
程式名稱(Program name)：jpg2pdf.py
程式內容(Code)：
from PIL import Image
import os
#取得當前目錄
Path = os.getcwd()
#取得input路徑
InputPath = Path+'\\input\\'
#取得input資料夾下的目錄或檔案
dirs = os.listdir(InputPath)
# 建立字典與串列
pdfname = dict()
pdfadds = []
jpglist = []
#逐一檢查input資料夾下的目錄或檔案
for dir in dirs:
#print(dir)
#目錄的處理
if os.path.isdir(InputPath+'\\'+dir+'\\'):
pdfadds = os.listdir(InputPath+'\\'+dir)
pdfname[dir] = pdfadds
#檔案的處理
elif os.path.isfile(InputPath+'\\'+dir):
#檢查檔案副檔名為jpg
if dir.split('.')[1] == 'jpg':
jpglist.append(dir)
# 目錄-> jpglist
pdfname['input'] = jpglist
#jpg 轉 pdf
for key in pdfname.keys():
TempIm_list = []
Tempk = 0
TempPdfName = str(key+'.pdf')
for i in pdfname[key]:
if key != 'input':
# 處理放在資料夾內的jpg
ImagePath = InputPath+'\\'+key+'\\'+i
elif key == 'input':
# 處理放在input 的jpg
ImagePath = InputPath+'\\'+i
Tempk = Tempk + 1
if Tempk == 1:
TempImage_1 = Image.open(ImagePath)
TempIm_1 = TempImage_1.convert('RGB')
else:
TempImage = Image.open(ImagePath)
TempIm= TempImage.convert('RGB')
TempIm_list.append(TempIm)
TempIm_1.save(TempPdfName,save_all=True,append_images=TempIm_list)
4.
