Writing your own functions (4/5)
By this time we always returned some information in the function body. But rarely we don't need to return and save any values after function execution, for example, if we need to just print something.
Remember our dictionary with some countries' information? Let's write a function that will print all the information we needed with only two arguments: dictionary and country name.
