What is the use of the "read" method in a Python file?

The "read" method in Python is used to read the contents of a file. It is a method of a file object and takes one optional parameter, the number of characters to be read from the file. If the parameter is not specified, the entire contents of the file are read. The "read" method returns a string that represents the contents of the file. For example:

f = open("example.txt", "r")
contents = f.read()
f.close()

print(contents)

This opens the file "example.txt" in read mode, reads the contents of the file into a string called "contents", closes the file, and then prints the contents of the file.
