Python：從不同的循環打印變量

Question

for synset in wn.synsets(wordstr): 
    len_lemma_names = len (synset.lemma_names) 
    #print len_lemma_names, synset.lemma_names 
    count_lemma = count_lemma + len_lemma_names 
for synset_scores in swn_senti_synset: 
    count_synset = count_synset + 1 
    #print count_synset, synset_scores 

我想在count_synset前面打印len_lemma_names，但它不起作用。有沒有辦法將它們打印在一起？謝謝...

Answer 1

我認爲你想要一起迭代兩者。如果是這種情況，您希望使用zip，或者避免將它全部變成一個大列表，itertools.izip。

from itertools import izip 

for synset, synset_scores in izip(wn.synsets(wordstr), swn_senti_synset): 
    # Now you can deal with both at once in this loop. 
    len_lemma_names = len(synset.lemma_names) 
    count_lemma += len_lemma_names 
    count_synset += 1 
    # Mix to taste. 
    print len_lemma_names, count_synset 

注意，count_synset一部分也可以用enumerate可以做得更好（我不知道它的初始值，或無論你想使用它的代碼外）。
