Telegram bot optimization) Can you help?

Question

Python

Hello. Faced the problem of optimizing my telegram bot. He parses and searches for weather on demand online in 44 cities of my country. For each city in the class, a parser is written as a class method.
Now I want to simplify the task and redo the algorithm. I want to make a dictionary where the key is the city and the value is the link. From this question. Does a Python dictionary iterate faster than a class?
