Function calls in Clojure work the same as any mainstream languages, such as Python. The main difference is that the function name comes after the parenthesis in the Clojure version.

​ functionName(​param1,​ param2)
​ 
​ (​function-name​ param1 param2)

This difference can be explained very simply. The function call is just a list containing the function name and its parameters. In Clojure, a list is a special type of data structure reserved for creating callable expressions. To create a list data structure, we have to call the list function:

​ (list 1 2 3)
