在Python中將fetch_all數組轉換爲單個數組

Question

在python中，我從數據庫獲取了fetchall數據。

SENTENCE = "It is wonderful. I'am happy" 
sent= (word_tokenize(SENTENCE)) 

cursor = conn.cursor() 
format_strings = ','.join(['%s'] * len(sent)) 
cursor.execute("SELECT emotion_type FROM emotion WHERE key_word IN (%s)" % format_strings,tuple(sent)) 
results = cursor.fetchall() 
for i in results: 
     z= (i) 

輸出是

('happy',) 
('happy',) 

但我希望得到這個結果作爲

['happy','happy'] 

如果有任何可能的方式來獲得輸出，因爲我想。請幫幫我 ！

Answer 1

如果結果只會是從一列，那麼你可以隨時做

results = [res[0] for res in cursor.fetchall()]
