Python :

rewrite the factorial function so that everytime it calls itself it adds an indentation $($see examples$)$

#here is our original definition

def factorial$($ n $)$:

if n $<=1$:

return $1$

return n $*$ factorial$($ n$-1)$

In the example $($below$)$ it is easy to see all the recursive calls to the factorial function.

your file must be called fact.py$.$

in that file you must define a function called factorial

end the file with the following line $($so that it asks for input$)$

for this to work your function must print something everytime it is called, and it must print something everytime it returns a value. factorial$($int$($input$("$enter an integer: $")))$

Examples

$\%$ python$3$ fact.py

enter an integer: $5$

factorial$(5)$

factorial$(4)$

factorial$(3)$

factorial$(2)$

factorial$(1)$

returns $1$

returns $2*1=2$

returns $3*2=6$

returns $4*6=24$

returns $5*24=120$

$\%$
