比如把[['cola', 'juice', 'coffee', 'tea'],['cola', 'juice', 'tea', 'coffee'],['cola', 'juice', 'coffee', 'tea']]轉換成{('cola', 'juice', 'coffee', 'tea'): 2,('cola', 'juice', 'tea', 'coffee'): 1}在編譯器中for i in a:if(b.has_key(tuple(i))==False):b[tuple(i)]=1else:b[tuple(i)]+=1是可行的
可是不讓用 print, input..怎么寫函數來實行?
