Error if call.data == "1": NameError: name 'call' is not defined why does it occur?

Question

Python

Here is the code:

This is the calculator code
. The error, as I understand it, is due to the fact that the code is large and it does not see the library

Answer 1

Before creating anything, it is better to read some books / watch videos. And also familiarize yourself with the library with which you work. If you ask a question for every mistake, things will not go further, learn the basics.
