Thanks in advance for the help!

Answer 1

You are opening the file with the mode parameter for open() set to "a" which is for writing only.

Here is a summary of the different parameters: from: https://docs.python.org/3/library/functions.html#open

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

So for use case to read and write to the file try changing it to:

f = open("demoofile1.txt", "r+")
