How can I handle errors in Python when attempting to read a file more than two times?

While working with files, I am encountering errors when I am trying to use the read functions like read(), readline() or readlines(). The functions work fine the first time I use them after opening the file, but they don’t work when I use them again. I am unaware what to do in this case as I am new to file processing in Python, if anyone can help me in this by providing some example codes, I would highly appreciate it.
