open(img_file) out_img = in_img.resize(desktop_size) return out_img 在这里,我们有三种策略,每种策略都使用PIL来执行它们的任务。各个策略都有一个make_background方法,接受相同的参数集。一旦选择,就可以调用适当的策略来创建正确大小的桌面图像。TiledStrategy循环遍历可以适应图像宽度和高度的输入图像数量,...
readlines() :Reads all the lines and return them as each line a string element in a list. File_object.readlines() file.read() 读取文件的所有内容,并以变量的形式返回。如:f = file.read()。这里file是目标文件,打开时需要设置可读模式。
