如何将单个元素元组转换为字符串？

Question

我有这个代码:

 import nltk
 import pypyodbc

 text = raw_input()
 token = nltk.word_tokenize(text) //return a list value


def search(self, lists):
    if not self.connected:
        self.connect()
    for word in lists:
        self.cur.execute('SELECT Ybanag FROM Words WHERE English IN (%s)' % (','.join('?'*len(lists))), lists)
        result = self.cur.fetchall()
        return result

其中输出是单个元素元组的列表(例如,我输入we all there):( [('tore',), ('ngaming',), ('sittam',)]将输入翻译成母语).我想将输出转换为字符串以消除[],(),'','符号.如何将其转换为字符串？

Answer 1

你必须使用str.join方法.

>>> a = [('tore',), ('ngaming',), ('sittam',)]
>>> " ".join([x[0] for x in a])
'tore ngaming sittam'
