The file is already closed (when the previous with block finishes), so you cannot do anything more to the file. To reopen the file, create another with statement and use the read attribute to read the file.
with open('test_output.txt', 'r') as f2:
data = f2.read()
print(data)

io — Core tools for working with streams
It deals with streams whose bytes represent text, and handles encoding and decoding to and from strings. TextIOWrapper, which extends TextIOBase, is a buffered text interface to a buffered raw stream (BufferedIOBase).

TextIOWrapper‽ converting files to strings in Python - Python Morsels
February 5, 2024 - Ever encountered an _io.TextIOWrapper object when you wished you had a string? That's Python's version of a "text file" object!
TypeError: '_io.TextIOWrapper'
Opening a file creates a file object, or more specifically a _io.TextIOWrapper object, it doesn't magically create a dictionary as most files aren't dictionaries. You'll need to parse your file in some way to create a dictionary. I'd suggest saving your file as a JSON file and using the builtin json module. More on reddit.com

r/learnpython on Reddit: TypeError: '_io.TextIOWrapper'
November 28, 2022 -
I'm supposed to create a dictionary from the values in a file and search for 'Polly' and remove it if it's in the file,
I kept getting errors so I'm just trying to get it to print the value just so I can see what I'm doing wrong and even at the most simple level I keep getting errors,
I'm in my first semester so this is all still new to me
employees = {}
employees = open('dictionary_values.txt', 'r')
print(employees['Polly'])
Traceback (most recent call last):
File "main.py", line 3, in <module>
print(employees['Polly'])
TypeError: '_io.TextIOWrapper' object is not subscriptable

import json # this just loads a file object. It is best to use with syntax so it closes automatically. with open('dictionary_values.txt', 'r') as employees_file_object: # a very common method on file objects is to .read() which saves the text on the file as a single string. employees_file_text = employees_file_object.read() # now we have a JSON string. We need to convert the string into a JSON object using the json module we imported above. employees = json.loads(employees_file_text) # Now you can .pop() off the Polly key/value pair - if it doesn't exist it should be fine. employees.pop('Polly') # this will be an object with no Polly. print(employees) # if you need to then write it to the file, you will do the reverse process above, try to figure out which methods to convert object to string and write to the same file. Your txt file needs to be proper JSON string. Edit: a more educating answer.

Make io.TextIOWrapper/open support custom line terminators/record separators - Ideas - Discussions on Python.org
December 20, 2023 - My team routinely deals with all sorts of proprietary file formats from various customers. Many of those file formats are records with peculiar record separators that we have to use either str.split, re.split or re.finditer to parse. Wouldn’t it be nice if io.TextIOWrapper, and by extension, the open function, supports alternative characters as line terminator, so we can take advantage of one of the most beautiful idioms of Python, reading “lines” with a for loop over a file-like object?

Files and While Loops
This opens the file named story.txt from the current directory. It is open for reading (that's the r mode) and the type of object is io.TextIOWrapper. Don't stress about the type at all. Just think of it as an open file. The important conceptual idea here is that this object not only knows the contents of the file, but it knows our current position in the file.

That expression for line in file splits (streams more accurately) the file by the new line delimiter until it reaches EOF. Think of it a stream that reads until it's a new line, and then returns the characters it just read.

File-like objects are iterators that produce a line of text on each iteration. Iterators in general just means "things you can loop over exactly once"; files differ from this pattern on insofar as they can (depending on what the represent) be seeked, which would reset the iterator to a new position in the file.
To be clear, they are not sequences; the term "sequence" has specific meaning, and includes the ability to index it, iterate it multiple times in a row or in parallel, all without manually fixing up state.

The file object returned by open() function is an object of type _io.TextIOWrapper. The class _io.TextIOWrapper provides methods and attributes which helps us to read or write data to and from the file.

r/learnpython on Reddit: [Help] Why am I getting io.TextIOWrapper results in this ATBS project
June 21, 2018 -
I am doing one of the practice projects from chapter 9 of ATBS where you have to write a program that opens all text files in a folder and searches for any line that matches a regular expression.
here is my code
and here is the output
I am nowhere near finished with it yet and I'm sure there are other problems with what I've got so far, but I'm mainly concerned with the io.TextIOWrapper issue in the for loop.
It may be (probably is) caused by the way I'm trying to split the list and read each file, if that's the case, what is a better way to tackle opening each file individually? But I also want to know why the io.TextIOWrapper message is coming up for future reference.
Any help greatly appreciated! Sorry for making you look at hideous code!

Confused about documentation of io.TextIOWrapper encoding - Documentation - Discussions on Python.org
November 15, 2022 - Hi, The io.TextIOWrapper documentation claims that the default encoding is locale.getencoding(). The getencoding function ignores UTF-8 mode. But I thought the whole point of UTF-8 mode was to make UTF-8 encoding the default, especially for text IO. Example: $ LC_ALL=en_US.ISO8859-1 python -X utf8 Python 3.11.0rc2 (main, Sep 13 2022, 00:00:00) [GCC 12.2.1 20220819 (Red Hat 12.2.1-1)] on linux Type "help", "copyright", "credits" or "license" for more information.

A Python file object is created when a file is opened with the open() function. You can associate this file object with a variable when you open a file using the with and as keywords. For example: with open('somefile.txt') as file_object: You can then print the content of the file object, file_object with print(). print(file_object) You might see something like this on the output terminal: <_io.TextIOWrapper name='somefile.txt' mode='r' encoding='UTF-8'> To read only one line instead of multiple lines in a Python file, use the method .readline() on a file object that is returned from the open() function.
