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)

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).

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'])

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.

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.

You need to use the output of f.read().
string = f.read()
I think your confusion is that f will be turned into a string just by calling its method .read(), but that's not the case. I don't think it's even possible for builtins to do that.
For reference, _io.TextIOWrapper is the class of an open text file. See the documentation for io.TextIOWrapper.
By the way, best practice is to use a with-statement for opening files:
with open("document.txt", "r", encoding='utf-8-sig') as f:
string = f.read()

This is good:
with open(file, 'r', encoding='utf-8-sig') as f:
data = f.read()
This is not good:
with open(file, 'r', encoding='utf-8-sig') as file:
data = file.read()

In the cell below, we open the file my_file.txt, storing the value returned into a variable named fin (which stands for file input). We then print the type of fin, and see that it has type _io.TextIOWrapper.

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.
