python - difference between print and return -

this question has answer here:

• why use return statement in python? 12 answers

if print result of for loop in function:

def show_recommendations_for_track(tracks = [], *args):      results = sp.recommendations(seed_tracks = tracks, limit=100)     tracks = results['tracks']     track in tracks:         print track['name'] 

it prints 1 hundred track names.

if swap print return track['name'],

it prints 1 track name.

why?

return stops execution of whole function , gives value callee (hence name return). because call in loop, executes on first iteration, meaning runs once stops execution. take example:

def test():     x in range(1, 5):         print(x)         return x  test() 

this give following output:

1 

this because loop starts @ 1, prints 1, stops execution @ return statement , returns 1, current x.

---

return near same print. print prints output, return returns given value callee. here's example:

def add(a, b):     return + b 

this function returns value of a+b callee:

c = add(3, 5) 

in case, c, when assigning, called add. result returned c, callee, , stored.
