PermissionError: [Errno 13] Permission denied: 'name.pdf'
目录
PermissionError: [Errno 13] Permission denied: 'name.pdf'
问题：
因为我们在使用fpdf生成pdf的时候前面相同位置的同一个pdf正处在被打开的状态，所以无法创建。
解决：
我们可以关闭这个打开的同位置同名的pdf或者使用浏览器打开我们需要调试的pdf;
from fpdf import FPDF
from PIL import Image
import os
now = datetime.now() # current date and time
date_time = now.strftime("%Y-%m-%d")
