Python: Incident causing wrong result? -

-

the following code expected return 'none', however, seems i've done wrong incident:

def function_that_prints():     print "i printed"     f1 = function_that_prints()     print f1

i've tried putting 3rd line left aligned it's still not happening. please correct me, thanks!

with third line indented part of function, function_that_prints() recurses (it calls itself) indefinitely , python raise runtimeerror complaining maximum recursion depth has been exceeded.

if not indent third line have following code snippet:

def function_that_prints():     print "i printed" f1 = function_that_prints()  print f1  # running produce: # printed # none

the statement f1 = function_that_prints() print "i printed" , set f1 none, suggested.

then statement print f1 print value of f1, none.
