在python中,return()和print()会对以下代码产生不同的影响.有什么不同？为什么？

def count_wins(teamname):
    wins = 0
    for team in nfl:
        if team[2] == teamname:
            wins +=1
    return wins

def count_wins(teamname):
    wins = 0
    for team in nfl:
        if team[2] == teamname:
            wins +=1
    print wins

nfl = [[''2009','1','Pittsburgh Steelers','Tennessee Titans'],['2009','1','Minnesota Vikings','Cleveland Browns']]
