#Using recursion to get fibonacci numbers
#Our getFib function, needs a whole number
def getFib(number):
#assert the number is whole
assert(isinstance(number,int)),"Needs a whole number"
#Base case. When the number is 1
#we know what we want to return
#so there is no need for more recursion
#we can just return our value
if number == 1 or number ==0:
return 1
#For any number apart from 1
#we do another recursion of the program
#this will happen until number == 1
else:
return getFib(number-1)+getFib(number-2)
print("10th fibonacci number: %i" %getFib(10))
print("20th fibonacci number: %i" %getFib(20))
