在上面的示例中,我们定义了一个名为 get_disk_usage 的函数,该函数返回根文件系统的磁盘使用率。该函数使用 subprocess.run 函数来执行 df 命令,并将其输出解析为 Python 对象。然后,我们从输出中提取出磁盘使用率,并将其作为整数返回。 要使用此函数,只需调用 get_disk_usage 并将其结果打印到控制台上即可。
Gigabytes (GB), Terabytes (TB), and so on. The file sizes can be measured using a binary system (where kilo means 1024) or metric system (kilo means 1000). We can follow different approaches to get the file size in Python. It’s important to get the file size in Python to monitor...

SciencePlots是一款用于科学绘图的Python工具包。 当我们看学术期刊、论文时会看到各种各样高大上的图形。会好奇,这么好看的图到底怎么画的?是不是很困难? 的确,现在很多Python绘图工具只是关注图形所表达的数据信息,而忽略了样式。 SciencePlots则弥补了这片空白,它是一款专门针对各种学术论文的科学绘图工具,例如,scien...
/proc 文件虚拟系统是一种内核和内核模块用来向进程(process)发送信息的机制(所以叫做“/proc”),这个伪文件系统允许与内核内部数据结构交互,获取有关进程的有用信息,在运行中(on the fly)改变设置(通过改变内核参数)。与其他文件系统不同,/proc 存在于内存而不是硬盘中。proc 文件系统提供的信息如下:...
my_file = open(“C:/Documents/Python/test.txt”, “r”) print(my_file.readline()) Output: Hello World Using this function we can read the content of the file on a line by line basis. Output: Example 5: my_file = open(“C:/Documents/Python/test.txt”, “r”) ...
Much of the text on the Web is in the form of HTML documents. You can use a web browser to save a page as text to a local file, then access this as described in the later section on files. However, if you’re going to do this often, it’s easiest to get Python to do the ...
