示例1: pic_to_ppt
# 需要导入模块: from pptx import util [as 别名]
# 或者: from pptx.util import Inches [as 别名]
def pic_to_ppt(filename): #前提是图片文件名全为数字，否则还需要修改
if not os.path.exists(filename):

ppt = pptx.Presentation()
pic_path=[]
for i in os.walk(filename).__next__()[2]:
if i.endswith('.png'):
pic_path.append(i)
#若是不全为数字，则可尝试运行下列代码
# ls=[]
# for png in pic_path:
# s=''
# for item in png:
# if item<='9' and item>='0':
# s+=item
# ls.append(s+'.png')
# pic_path=ls
pic_path.sort(key=lambda item:int(item.split('.')[0]))
for i in pic_path:
i='{}/{}'.format(filename,i)
