Crash report
What happened?
This code showing the first 20 Fibonacci numbers works fine:
from itertools import *
def Fibonacci():
parts = [(0, 1)]
whole = chain.from_iterable(parts)
output, feedback = tee(whole)
parts.append(map(sum, pairwise(feedback)))
return output
print(*islice(Fibonacci(), 20))Output (Attempt This Online!):
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181
But if I keep a reference, it crashes (after successfully printing the numbers):
from itertools import *
def Fibonacci():
parts = [(0, 1)]
whole = chain.from_iterable(parts)
output, feedback = tee(whole)
parts.append(map(sum, pairwise(feedback)))
return output
f = Fibonacci()
print(*islice(f, 20))The error output (Attempt This Online!):
