Python file close() usage and example

Python File (File) Method

Overview

close() This method is used to close an opened file. After closing, the file can no longer be read or written. Otherwise, it will trigger ValueError Error. The close() method can be called multiple times.

When the file object is referenced to operate another file, Python will automatically close the previous file object. It is a good habit to close the file using the close() method.

Syntax

The syntax of the close() method is as follows:

fileObject.close();

Parameter

• None

Return value

This method does not return any value.

Example

# Open the file
fo = open("w3codebox.txt, "wb")
print("The file name is:　", fo.name)
# Close the file
fo.close()

The output result of the above example is:

The file name is:　　w3codebox.txt
