Pycharm error when using requests library?

Question

PyCharm

Hello, please help with the telegram bot, when compiling this code, it gives a lot of errors, and it's not clear what to do about it, maybe someone faced a similar problem when creating a bot?
Python itself works, there is a requests library.

Answer 1

Rest, hard workers, my ISP is just blocking telegrams

Answer 2

Wrapping in a function allows you to escape the context to separate internal variables from external ones.
For example:

var a = 3;
(function(a) {
  console.log(++a); // выведет 4
} (a));
console.log(a); // выведет 3

Answer 3

Self-calling function with "i" argument passed, executed immediately after startup
