I’m a newbie to Python, with a Java background. I came across the following function definition
def S(seq,i=0):
print i
if i==len(seq):
return 0
return S(seq,i+1)+seq[i]
What exactly does the i=0 do here, is it re-initialised to 0 each time? Because I notice that the value of i is incremented .
It provides the default value for the second argument.
The function can be called with either one or two arguments. If it’s called with one, the second argument,
i, defaults to zero.
