"WebThe same kind of diagram can help interpret a recursive function. Every time a function gets called, Python creates a frame to contain the function’s local variables and parameters. For a recursive function, there might be more than one frame on the stack at the same time. Figure [fig.stack2] shows a stack diagram for countdown called with n = 3. " - Recursion's 2k
