Reading notes on the book "Python Programming Quick Start (2nd Edition)" 5. File Operations (1) [Copy link]

This study document related operations.

1. Folder separator of the path

In Windows, path writing uses backslashes as separators between folders. However, in macOS and Linux operating systems, forward slashes are used to separate paths.

In order to uniformly handle the file path differences between different systems, Python provides a pathlib module (the Path() method in it) that can easily handle this problem.

The Path() method returns a string representing the file path.

2. Use the / operator to connect paths

Python can directly use / to connect paths, but the prerequisite is that the previous path uses the Path() method.

For example:

It is particularly important to note that when using the / operator to connect paths, the / must be preceded by a Path object.

3. Current working directory

Python can use the Path.cwd() function to get the string of the current working path, and can use the os.chdir() function to change it, as shown in the following example:

Alternatively, you can also use the os.getcwd() function to get the current working directory, but this is an older method.

4. Main Directory

Each user on the computer has his own folder, which is called the home directory. The home directory can be obtained through the Path.home() function.

5. Create a new folder

Python can create new folders using the os.makedirs() function.

This method can create multiple directories at one time.

There is more knowledge related to file operations, which I will continue to learn next time.

Brother, are you also learning? I have just started learning and I don’t know how long I can stick with it.

Building a Linux virtual machine makes learning more interesting.

You need to find a way to apply this knowledge to actual projects, otherwise you won’t be able to remember it and it’s easy to give up.

Haha, Linux is all files, it's OK

Python is indeed very convenient, mainly at the application level

Uh-huh, yes
