Python File Operations: Open and Release (Close) Files

The 'open' function in file operations is used to open a file and return a file object. It takes two parameters: the file name/path and the mode in which the file should be opened.

Example usage of 'open' function:

file = open('example.txt', 'r')

In the above example, the 'open' function is used to open the file named 'example.txt' in read mode ('r'). The returned file object is stored in the variable 'file'.

The 'release' function is not a built-in function in Python. It might refer to releasing system resources, such as closing a file or releasing a lock. In the context of file operations, the 'close' function is used to release system resources associated with a file object.

Example usage of 'close' function:

file.close()

In the above example, the 'close' function is called on the file object 'file' to release system resources associated with it.
