python实现快速文件格式批量转换的方法

// 导入PIL，os，glob
from PIL import Image
import os,glob

// 创建输出文件夹
def batch_change(in_path,out_path): 
  if not os.path.exists(out_path):
    print(out_path,'is not existed.')
    os.mkdir(out_path)
  if not os.path.exists(in_path):
    print(in_path,'is not existed.')
    return -1

// 浏览遍历输入文件夹
  for files in glob.glob(in_path+'/*'):
    filepath,filename=os.path.split(files)
    out_file = filename[0:9]+'.jpg' #转换成最终格式为.jpg，可以在这里改为.png
    im = Image.open(files)
    new_path=os.path.join(out_path,out_file)
    print(count,',',new_path)
    count = count+1
    im.save(os.path.join(out_path,out_file))

// 浏览遍历输入文件夹
  if __name__=='__main__':
  batch_change(r'C:\Users\80610\Desktop\in_path',r'C:\Users\80610\Desktop\out_path') 
  #你想转化文件所在文件夹输入和输出的路径

#encoding = utf-8
#author = itinerary,hui

from PIL import Image
import os,glob

def batch_change(in_path,out_path): #参数：输入与输出文件夹路径
  if not os.path.exists(out_path):
    print(out_path,'is not existed.')
    #创建输出文件夹
    os.mkdir(out_path)
  if not os.path.exists(in_path):
    print(in_path,'is not existed.')
    return -1
  count = 0
  for files in glob.glob(in_path+'/*'):
    filepath,filename=os.path.split(files)
    out_file = filename[0:9]+'.png' #转换成最终格式为png
    im = Image.open(files)
    new_path=os.path.join(out_path,out_file)
    print(count,',',new_path)
    count = count+1
    im.save(os.path.join(out_path,out_file))

if __name__=='__main__':
  batch_change(r'C:\Users\80610\Desktop\in_path',r'C:\Users\80610\Desktop\out_path') #你想转化文件所在文件夹输入和输出的路近
