Non-UTF-8 error in PyCharm, what to do about it?

Question

PyCharm

When I run the code, I get the error Non-UTF-8 code starting with '\xd0', what should I do about it? Explain, please, in more detail, because. I'm quite new and don't understand what coding is, all these types etc. (photo of error and code below)

Answer 1

Your source code is not typed in UTF-8 encoding, or Python did not understand what it is typed in.
a) See what encoding is selected in the Pycharm settings.
b) Add a line to the beginning of the file indicating the encoding, for example
# -*- coding: utf-8 -*-
if the file is still in utf-8 or
# -*- coding: windows-1251 -*-
if the file is typed in Windows default encoding.
