Write me a Python function for a parser must be a string or character stream, not a timestamp.

Here is a Python function for a parser. The string or character stream must be a timetamp, not a string

import os

def parser(file_obj):
    """
    This function parses the file and returns the content.
    """
    return file_obj.read()

# Enter the file name
file_name ="yellow submarine"

# Open the file
file_obj = open(file_name, "r")

# Calling the function
file_content = parser(file_obj)

# Print the file content

#Remember to inspect code for bugs.
