Can someone help me fix this dumb question?

Question

u=list()
def CalculFiboTupleIt( (a,b),(u,u1),n):
global u
for i in range(2,n):
u[i]=-a*u[i-1]-b*u[i-2]
return u[n-1]
print(CalculFiboTupleIt((-1,-1),(0,1),6))
My computer shows an error message when I try to run this code... Why?
The error message is:
File "<tmp 4>", line 1
def tuple((a,b),n):
^
SyntaxError: invalid syntax

Answer 1

You can't have function parameters within tuples, or lists, etc. You can do this, however:
def tuple(a,b,n):
...
where a and b are tuples. Of course, you'd need to use a[0], a[1], etc. to access the elements within them in the function.
