Working with files in Python An error occurs while reading the file. What is the reason?

Question

Python

Hello. I can not understand. Simple code :

with open('textfile_2.txt', 'tw', encoding='utf-8') as f1:
    f1.write("Привет русский текст")
    f1.read()

An error pops up:

Traceback (most recent call last):
  File "Диск:/Lessons/python-projects/book1/files/ИМЯ ФАЙЛА.py", line 69, in <module>
    f1.read()
io.UnsupportedOperation: not readable

Answer 1

Set file open mode to read

Answer 2

It confuses me a little that you open the flag for writing 'w', and then you try to read something on it. There are two ways out - either reopen the file for reading-writing, or refuse one of the operations.
PS: after a little thought, I came up with the idea that you are reprinting some kind of listing. And there the mode is not 'tw', but 'rw' (t and r are adjacent letters in the layout). And 'rw' is just the "read-write" mode.

Answer 3

Thank you. He fooled himself. Everything worked.
with open('text_1', 'r', encoding='utf-8') as f1:
print(f1.read())
or
f = open('text_1', encoding='utf-8')
print(f .read())
f.close()
