废话不多说！上来就是精华

案例一:

业务场景: 一个文件夹中有很多图片,图片的格式有两种一个是TIF,一个是GIF，两两对应，如果有单独的存在,那么就需要把对应的给图片转换出来 例如：只有1.GIF 那么我就需要将1.TIF 给弄出来或者 只有2.TIF那就就需要将2.GIF给弄出来

方法一

import os from PIL import Image path = "C:\\Users\\Administrator\\Desktop\\tif" #文件夹目录 dirs= os.listdir(path) #得到文件夹下的所有文件名称 list2=[] list1=[] for file in dirs: if file.endswith(".tif"): list1.append(file.split(".")[0]) if file.endswith(".gif"): list2.append(file.split(".")[0]) imagesList=[] d=[i for i in list1 if i not in list2] for only_image in d: for images in dirs: if images.__contains__(only_image): imagesList.append(images) f=[i for i in list2 if i not in list1] for only_image in f: for images in dirs: if images.__contains__(only_image): imagesList.append(images) print(imagesList) def IsValidImage(img_path): """ 判断文件是否为有效（完整）的图片 :param img_path:图片路径 :return:True：有效 False：无效 """ bValid = True try: Image.open(img_path).verify() except: bValid = True return bValid def transimgTIF(img_path): """ 转换图片格式 :param img_path:图片路径 :return: True：成功 False：失败 """ if IsValidImage(img_path): try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".tif" print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False def transimgGIF(img_path): """ 转换图片格式 :param img_path:图片路径 :return: True：成功 False：失败 """ if IsValidImage(img_path): try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".gif" print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False if __name__ == '__main__': for ImagePath in imagesList: if ImagePath.__contains__(".tif"): # print(path+'\\'+ImagePath) a=transimgGIF(path+'\\'+ImagePath) print(a) if ImagePath.__contains__(".gif"): # print(path+'\\'+ImagePath) a=transimgTIF(path+'\\'+ImagePath) print(a)

方法二

import os,datetime from PIL import Image path = 'C:\\Users\\Administrator\\Desktop\\image' start = datetime.datetime.now() def IsValidImage(img_path): bValid = True try: Image.open(img_path).verify() except: bValid = False return bValid def transimgTIF(img_path): if IsValidImage(img_path): try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".tif" # print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False def transimgGIF(img_path): if IsValidImage(img_path): try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".gif" # print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False def fun(path):#含子文件夹 for (root, dirs, files) in os.walk(path): for filename in files: ImagePath=os.path.join(root,filename) if os.path.exists(ImagePath.split(".")[0]+'.tif')& os.path.exists(ImagePath.split(".")[0]+'.gif'): print() else: if ImagePath.__contains__(".gif"): transimgTIF(ImagePath) if ImagePath.__contains__(".tif"): transimgGIF(ImagePath) fun(path) end = datetime.datetime.now() print(end-start)

方法三

import os,datetime from PIL import Image path = 'C:\\Users\\Administrator\\Desktop\\tgif' start = datetime.datetime.now() def IsValidImage(img_path): bValid = True try: Image.open(img_path).verify() except: bValid = False return bValid #594，398 def transimgTIF(img_path): if IsValidImage(img_path): # print(img_path+"传递过来的是gif") try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".tif" print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False def transimgGIF(img_path): if IsValidImage(img_path): # print(img_path+"传递过来的是tif") try: str = img_path.rsplit(".", 1) output_img_path = str[0] + ".gif" print(output_img_path) im = Image.open(img_path) im.save(output_img_path) return True except: return False else: return False def fun(path):#含子文件夹 imagePath=[] for (root, dirs, files) in os.walk(path): for filename in files: ImagePath=os.path.join(root,filename) imagePath.append(ImagePath) conn=imagePath set_dir=set([ i.rsplit(".")[0] for i in conn]) # print(set_dir) for dir in set_dir: if dir+".tif" not in imagePath: # print(dir+".gif") transimgTIF(dir+".gif") if dir + ".gif" not in imagePath: # print(dir + ".tif") transimgGIF(dir + ".tif") fun(path) end = datetime.datetime.now() print(end-start)

案例二：

业务场景：

方法一

import os,datetime import shutil from PIL import Image ''' @path: 所有图片字母里的父目录 例如: C:\\Users\\Administrator\\Desktop\\udev\\adcc\\dsdsds\\ccss\\group\\DDMS C:\\Users\\Administrator\\Desktop\\udev\\adcc\\dsdsds\\ccss\\group\\DDMA C:\\Users\\Administrator\\Desktop\\udev\\adcc\\dsdsds\\ccss\\group\\DDME @Parent_directory:为所有子文件的父文件夹的名称 父文件夹名称就为:group @new_path:要存放的新路径 ''' path = 'C:\\Users\\Administrator\\Desktop\\udev\\adcc\\dsdsds\\ccss\\group' Parent_directory='group' new_path='C:\\Users\Administrator\Desktop\ImageTIF' def fun(path):#含子文件夹 for (root, dirs, files) in os.walk(path): for filename in files: ''' ImagePath为所有图片的路径 ''' ImagePath=os.path.join(root,filename) ''' 判断A.tif和A.gif是否都存在 ''' if os.path.exists(ImagePath.split(".")[0]+'.tif')& os.path.exists(ImagePath.split(".")[0]+'.gif'): continue else: ''' 将对应不上的.tif取出来 ''' if ImagePath.__contains__('.tif'): ''' str为 ImagePath='C:\\Users\\Administrator\\Desktop\\udev\\caca\\3310A11.tif' str=[C:\\Users\\Administrator\\Desktop\\udev\\caca\\3310A11,.tif] str[0]=C:\\Users\\Administrator\\Desktop\\udev\\caca\\3310A11 new_ImagePath=每个子目录的文件名称 ''' str = ImagePath.rsplit(".", 1) new_ImagePath = str[0][str[0].index(Parent_directory) + len(Parent_directory + "\\"):-1].split('\\')[0] ''' 判断 new_path='C:\\Users\Administrator\Desktop\ImageTIF' new_ImagePath=‘DDMAK01’ new_path+new_ImagePath是否存在 存在直接将 ImagePath='C:\\Users\\Administrator\\Desktop\\udev\\caca\\3310A11.tif' 复制到 new_path+new_ImagePath 不存在先创建 再进行复制 ''' if os.path.exists(new_path+"\\"+new_ImagePath): shutil.copy(ImagePath,new_path+"\\"+new_ImagePath) else: os.mkdir(new_path + '\\' + new_ImagePath) shutil.copy(ImagePath, new_path + "\\" + new_ImagePath) fun(path)

很多层目录的图片该怎么办

import os from PIL import Image #原图片路径 path = 'C:\\Users\\Administrator\\Desktop\\group' Parent_directory="group" #GIF图片存放路径 new_Path='C:\\Users\\Administrator\\Desktop\\ce' def IsValidImage(img_path): bValid = True try: Image.open(img_path).verify() except: bValid = False return bValid def transimgGIF(img_path): if IsValidImage(img_path): try: str = img_path.rsplit(".", 1) new_ImagePath=str[0][str[0].index(Parent_directory) + len(Parent_directory+"\\"):-1] output_img_path = new_Path+'\\'+new_ImagePath+ ".jpg" im = Image.open(img_path) im.save(output_img_path,quality=100) return True except: return False else: return False def fun(path): for (root, dirs, files) in os.walk(path): for filename in files: ImagePath=os.path.join(root,filename) if ImagePath.__contains__('.tif'): new_ImagePath = root[root.index(Parent_directory) + len(Parent_directory + "\\"):] print(new_Path + '\\' + new_ImagePath) if os.path.exists(new_Path + '\\' + new_ImagePath): transimgGIF(ImagePath) else: os.makedirs(new_Path+'\\'+new_ImagePath) transimgGIF(ImagePath) if __name__ == '__main__': if os.path.exists(new_Path): fun(path) else: os.makedirs(new_Path) fun(path)
