在我的代码中,我不知道如何转到已存在或刚刚创建的文件夹并重复 IF。 import os MYDIR = ("test") CHECK_FOLDER = os.path.isdir(MYDIR) if not CHECK_FOLDER: os.makedirs(MYDIR) print("created folder : ", MYDIR) else: print(MYDIR, "folder already exists.") ...
Here, we'll check for the existence of thelog.txtfile in a similar way to the first example of theossection, but this time usingpathlibto do the job: frompathlibimportPath log_file=Path('log.txt') ifnotlog_file.exists(): # log file doesn't exist, create a blank one ...
CreateFolder(if not exists) section 覆盖已存在文件夹 OverrideFolder(Check if new_folder exists) OverrideFolder(Delete new_folder) OverrideFolder(Create new_folder) 假设我们需要在当前目录下创建一个名为data的文件夹,用来存放数据文件。我们可以通过以下代码来实现: importosimportshutil dir_name="data"ifos....
ha = args.hash_algorithmprint("File hashing enabled with {} algorithm".format(ha))ifnotargs.log:print("Log file not defined. Will write to stdout") 当组合成一个脚本并在命令行中使用-h参数执行时,上述代码将提供以下输出: 如此所示,-h标志显示了脚本帮助信息,由argparse自动生成,以及--hash-algorit...

在本章中,我们将讨论数学形态学和形态学图像处理。形态图像处理是与图像中特征的形状或形态相关的非线性操作的集合。这些操作特别适合于二值图像的处理(其中像素表示为 0 或 1,并且根据惯例,对象的前景=1 或白色,背景=0 或黑色),尽管它可以扩展到灰度图像。 在形态学运算中,使用结构元素(小模板图像)探测输入图像...
