Hi Group,
I just went through this article
http://docs.python-guide.org/en/latest/writing/gotchas/
written a Fibonacci program like this
def fibonacci(next=[1], prev=[0]):
data = prev.pop()
prev.append(next.pop())
next.append(prev[0] + data)
return data
for i in range(10):
print fibonacci()
It actually works, it prints first 10 fibonacci numbers
My question is the following code doesn't work the same way as i expected
it to work.
def fibonacci(next=1, prev=0):
data = prev
prev = next
next = data + next
return data
for i in range(10):
print fibonacci()
Instead of printing Fibonacci, it just prints 10 zeros
means.. does python only remembers the list in default argument?
