def oneLess(x:int):

     return x-1

1. The function is defined with keyword "def ",
2. Then the name of the function is passed ( in this example oneLess)
3. After the name, the parameter and the type of the parameter is defined between the parantheses.(here the parameter is x of type int)
4. Finally the function returns one less then the value passed with the "return x-1" command.
