I read few topics about implementation of switch case statement in Python (it is deprecated in Python btw...) and found out that people like it... really. Frankly speaking, I couldn't join them because I think that this statement is redundant. Effect of switch case could be reached by Python's instruments. It could be considered like a little design pattern. So, let's implement it in python... at least this is interesting. Main idea is make dictionary with options -> function and get function like value.
