How to count function calls?

Question

I want to count the function calls of the Ackermann function:

def A (m,n,s="%s):

print (s% ("A (%d,%d)" % (m,n)))
if m==0:
return n+1
if n==0:
return A (m-1, 1, s)
n2= A (m,n-1,s% ("A (%d,%%s)" % (m-1)))
return A (m-1,n2,s)

print (A (2,2))

Answer 1

The function looks incorrect when I paste into the editor. Please refer to StackOverflow at https://stackoverflow.com/questions/23047680/find-number-of-times-ackerman-function-is-called-in-JUMP_LINK__&&__python__&&__JUMP_LINK
