Today's article let's look at the close in Python , before we go into the article we first need to know what pythonclose is, what does close mean , It can be used in Python programming where it can play a role. These things we can all learn in today's article.

Overview :

The close () method is used to close an open file. The closed file can no longer read or write, or it will trigger a valueerror error. The close () method allows calls multiple times.

When the file object is referenced to manipulate another file, Python automatically shuts down the file object before it. Using the Close () method to close a file is a good habit.

The close () method syntax is as follows:

Fileobject.close ();

(The method has no return value)
