Q:
Iteration in a single line
I have some code of the form:
for i in range(nIterations):
y = f(y)
Where f is a function defined elsewhere. hopefully the idea of that code is that after it's run y will have had f applied to it nIterations times.
Is there a way in python to write this in a single line?
