如何在python中的一行中打印列表？

Question

如果我有这个代码，我需要在一行打印输出我怎么能这样做？

L = [('the', 'the'),('cat', 'cow'),('sat', 'sat'),('on', 'on'),('mat', 'mat'),('and', 'a'),('sleep', 'sleep')]

def getParaphrases(L):
   pre_match = 0
   mis_match = 0
   after_match = 0
   paraphrase = []
   newpar = []
   for x in L:
      if x[0] == x[1]:
         if not paraphrase == []:
            print '\n Paraphrase:', paraphrase
            paraphrase = []
         pre_match += 1
         mis_match = 0
      else:
         if pre_match >= 1:
            if mis_match == 0:
               paraphrase = []
            paraphrase.append(x)
         mis_match += 1
         if after_match >= 1:
            paraphrase.append(x)
            after_match += 1

输出是：

 Paraphrase: [('cat', 'cow')]

 Paraphrase: [('and', 'a')]

但是，如何在一行中获得输出，例如，

 Paraphrase [('cat', 'cow'), ('and', 'a') ]

Answer 1

您可以使用列表推导替换整个函数

L = [('the', 'the'),('cat', 'cow'),('sat', 'sat'),('on', 'on'),('mat', 'mat'),('and', 'a'),('sleep', 'sleep')]

[(i,j) for i, j in L if i != j]

输出

[('cat', 'cow'), ('and', 'a')]
